First make sure they are in the proper format including bit rate. I assume you know how to navigate the music folder with the dm-520. I find it helpful to turn play all files on in case there are sub folders. When you go to the music folder and press the right arrow one or more times you should hear one of them play if preview is on and if the files are compatible. .

Re: Laptop speakers question
It seems that with wifi, and things like it, you could use your laptop in, say, your living room, and use the speakers for your stereo or surround system.

Power from USB [was RE: Laptop speakers question]
I guess I have a different take on all of this. Contrary to what someone said early in the thread, the USB port was definitely designed to provide power to attached devices. Otherwise, the specification wouldn't have included this in the first place. In Wikipedia's definition of the Universal Serial Bus (USB) at http://en.wikipedia.org/wiki/Universal_Serial_Bus, it says The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire from which connected USB devices may draw power. Therefore, I don't see anything wrong with devices taking advantage of this and no one should worry about anything bad happening to their PC's or USB attached devices. In fact, Nokia, Samsung, Motorola, Sony Ericsson and LG have all settled on the micro USB port as their standard power port. China and the European Commission (EC) will also soon be requiring cell phones sold to use the USB port for power and charging. Of course, there are devices that pull more power than the USB port can provide. There are also non-standard devices, including a lot of USB decorations, such as lights, fans, cup warmers and so on that don't include the necessary electronics to support the USB specifications. These devices could potentially cause some erratic behavior on your PC. -- Christopher chalt...@gmail.com -Original Message- From: pc-audio-boun...@pc-audio.org [mailto:pc-audio-boun...@pc-audio.org] On Behalf Of DJ DOCTOR P Sent: Saturday, June 05, 2010 7:59 PM To: PC Audio Discussion List Subject: Re: Laptop speakers question Hello Bob, Again, I am in agreement with you on that one.

Re: Power from USB [was RE: Laptop speakers question]
That's where the problem lies with new consumer products coming on stream who's power source ends up being the USB port! It appears that there are no standards in place that dictates what can and what can not be used with this port! As I stated earlier I personally don't think that it was the intention of the manufacturer to have the consumer using this port to warm up a cup of coffee, power a hand massager, and other devices that demand a lot of electricity. The end result could easily end up being a potential fire hazard if that device is left on overnight and not fused and shorts out! We are already putting a significant amount of strain on portable laptop and notebook computers, as we are pushing them well beyond their limits. The more heat that is generated in the inner workings of these devices shortens their lifespand! Only in a bind would I use my USB port to charge a cell phone, a digital recorder etc. I have seen melted circuit boards, and blackened power packs, and believe me it is not a pretty sight!

Re: Power from USB [was RE: Laptop speakers question]
I have both my HP printer and my Microtek scanner plugged into USB ports on the back of my 6-year-old Dell desktop, leaving two USB ports in front of the tower for convenient docking of flash drives and such stuff. No problems at all. Those devices, I believe, were meant to be powered exactly this way. By contrast, my Norelco rechargeable electrickk razor was not.

Hello, your one-stop place is www.BagsUnlimited.com They have various sleeves for 78s, with various thicknesses of paper, center hole or not, and even cardboard or just paper. They also have inner static sleeves for 33s, as well as the mylar sleeves that fit over the record jacket, so that you could braille on the mylar sleeve with a labeling gun like I do, and you don't mark up the cover. You can also phone Bags Unlimited to make sure you're ordering exactly what you need, since it can sometimes be confusing.

RE: Power from USB [was RE: Laptop speakers question]
Ah well, I'm not going to tell anyone what he has to use his USB port for, and it's none of my business if someone chooses not to charge his cell phone with their USB port. I do hope though that people reading this thread don't get the wrong impression though. There are standards on how the USB port should be used. There are published specifications that PC manufacturers follow and devices using the USB port should also be following. That doesn't mean that there aren't USB port and devices that don't follow these specifications. It also isn't true that the USB wasn't intended to supply power to attached devices. That is obviously a big part of the USB standard. I also don't think we're pushing laptops well beyond their limitations. True, heat is a big enemy of electronics, and obviously not all laptops are created equal, but I don't think laptop manufacturers are intentionally building laptops that are far exceeding their limitations. There are specifications, standards and classical testing that are all used in the design and manufacture of laptops. My systems have USB ports on them, and I am going to use them for what they were intended for. I think virtually every device that doesn't have its own power source, uses at least a little power from the USB port. I don't have any USB decorations hooked up to my USB ports, but I do have devices that use a tiny bit of power such as keyboards, mice, sound cards attached. I also use devices like bluetooth dongles and hard drives that would take more power. I also attach MP3 players and cell phones to my USB ports that recharge themselves whenever they're plugged in. In fact, given what China, the EC, and most of the cell phone manufacturers and organizations have decided, I doubt there will be many cell phones manufactured from this point on that don't recharge themselves when hooked up to the USB port. Finally, if devices are left on leading to shorts and fires, that's obviously not the fault of the USB port and the specifications and standards that govern it. The same thing could be said of any power supply, such as the AC coming out of the socket on my wall. -- Christopher chalt...@gmail.com -Original Message- From: pc-audio-boun...@pc-audio.org [mailto:pc-audio-boun...@pc-audio.org] On Behalf Of Bob Seed Sent: Sunday, June 06, 2010 10:06 AM To: PC Audio Discussion List Subject: Re: Power from USB [was RE: Laptop speakers question] That's where the problem lies with new consumer products coming on stream who's power source ends up being the USB port! It appears that there are no standards in place that dictates what can and what can not be used with this port! As I stated earlier I personally don't think that it was the intention of the manufacturer to have the consumer using this port to warm up a cup of coffee, power a hand massager, and other devices that demand a lot of electricity. The end result could easily end up being a potential fire hazard if that device is left on overnight and not fused and shorts out! We are already putting a significant amount of strain on portable laptop and notebook computers, as we are pushing them well beyond their limits. The more heat that is generated in the inner workings of these devices shortens their lifespand!

HOW USB PORTS WORK
Hello all list members, I'm gonna try to explain how your USB ports work. And in the process of this, I'm also try to put away allot of misconceptions and myths about it. In 1986, the USB port was developed to transmit and receive digital information or if you will, data from the computer to other digital devices such as, printers scanners and fax machines. All of these devices usually have their own power supplies. Even though, 1.5 volts is needed to open up the data ports that are built in to the devices, the devices themselves, aren't powered by the USB ports. These days, the USB ports are used to open up the data ports on memory chips that are built in to storage devices such as, thumb drives external hard drives and MP3 players and IPods. As I said in an earlier post, your lab top and desk top computers have 12 volt power supplies powering them. In some electronic equipment, there are power/currant limiting resisters to reduce the voltage to what the engineer desires. But inside your computers, there is a chip that does a triple job. This chip cuts the high voltage down to what the storage devices can handle which is, 1.5 volts in to 135 MA. This chip also handles the transmitting and the receiving of data. This is why we're able to transfer audio/video files to our MP3 players and IPods. The same thing is also true about transferring pictures from digital cameras to our computers. The USB port was never mint to power devices alone. But in order to make the USB port a viable power supply, a couple of changes will have to be made. First, the voltage will have to be razed from 1.5 volts to pretty close to what the computers power supply is delivering. Next, the currant will have to be razed from 135 MA to about 1500 MA. But if we do this, the storage devices will overload and burn out. unless, you increase their capacity too as well. I hope I clarified the way your USB ports work. My best regards. John.

RE: HOW USB PORTS WORK
Interesting John, but some of what you say is contrary to what I'm finding on the web. For example, I'm reading that USB development didn't start until 1994. I'm also finding multiple sources where they say that USB can provide up to 5 V and 500 MA. I'll include some links and paste some text below. Note that one of the sources talks about how devices are connected in low power consumption mode and then negotiate for a higher power consumption. this may explain why you found that your USB port was only providing 1.5 V and 135 MA when you were testing it with your probe. From http://en.wikipedia.org/wiki/Universal_Serial_Bus, it says, among other things, that USB development wasn't started until 1994. Here's what it says in the history section of that web site: The Universal Serial Bus (USB) is a standard for peripheral devices. It began development in 1994 by a group of seven companies: Compaq, DEC, IBM, Intel, Microsoft, NEC and Nortel. USB was intended to make it fundamentally easier to connect external devices to PCs by replacing the multitude of connectors at the back of PCs, addressing the usability issues of existing interfaces, and simplifying software configuration of all devices connected to USB, as well as permitting greater bandwidths for external devices. The first silicon for USB was made available by Intel in 1995. [5] The USB 1.0 specification was introduced in January 1996. The original USB 1.0 specification had a data transfer rate of 12 Mbit /s. [5] The first widely used version of USB was 1.1, which was released in September 1998. It allowed for a 12 Mbps data rate for higher-speed devices such as disk drives, and a lower 1.5 Mbps rate for low bandwidth devices such as joysticks. [6] The USB 2.0 specification was released in April 2000 and was standardized by the USB-IF at the end of 2001. Hewlett-Packard, Intel, Lucent Technologies (now Alcatel-Lucent following its merger with Alcatel in 2006), NEC and Philips jointly led the initiative to develop a higher data transfer rate, with the resulting specification achieving 480 Mbit/s, a fortyfold increase over 12 Mbit/s for the original USB 1.0. data. I found another web site, http://www.wordiq.com/definition/USB, where it does a good job of explaining how the power supplied by the USB port works. Power supply The USB connector provides a single 5 volt wire from which connected USB devices may power themselves. A given segment of the bus is specified to deliver up to 500 mA. This is often enough to power several devices, although this budget must be shared among all devices downstream of an unpowered hub. A bus-powered device may use as much of that power as allowed by the port it is plugged into. Bus-powered hubs can continue to distribute the bus provided power to connected devices but the USB specification only allows for a single level of bus-powered devices from a bus-powered hub. This disallows connection of a bus-powered hub to another bus-powered hub. Many hubs include external power supplies which will power devices connected through them without taking power from the bus. Devices that need more than 500 mA or higher than 5 volts must provide their own power. When USB devices (including hubs) are first connected they are interrogated by the host controller, which enquires of each their maximum power requirements. The host operating system typically keeps track of the power requirements of the USB network and may warn the computer's operator when a given segment requires more power than is available (and will generally shut down devices or hubs in order to keep power consumption within the available resource). A number of devices use this power supply without participating in a proper USB network. The typical example is a USB-powered reading light, but fans, battery chargers (particularly for mobile telephones) and even miniature vacuum cleaners are available. In most cases, these items contain no electronic circuitry, and thus are not proper USB devices at all. This can cause problems with some computers - the USB specification requires that devices connect in a low-power mode (100 mA maximum) and state how much current they need, before switching, with the host's permission, into high-power mode. USB-powered devices attempting to draw large currents without requesting the power will not work with certain USB controllers, and will either disrupt other devices on the bus or fail to work themselves (or both). -- Christopher chalt...@gmail.com -Original Message- From: pc-audio-boun...@pc-audio.org [mailto:pc-audio-boun...@pc-audio.org] On Behalf Of Jörgen Hansson Sent: Sunday, June 06, 2010 8:53 PM To: PC Audio Discussion List Subject: Re: HOW USB PORTS WORK Hi there John! wow! that was the best info I have ever heard of, I didn't know that the USB port was in use in 1986.

RE: book sense. vs plextalk
For support of more audio formats such as m4a and Audible Enhanced, the Booksense is probably superior. and for sound output the Booksense is probably better, since there is a model with Bluetooth audio. For quality recording, the Plextalk Pocket is better.
