All > that for just one piece of hardware on the N800! On my 770 if you loaded the usb_gadget module it works. It just don't have any power like a standard USB port is supposed to. But if you plug it into a powered hub, you'll have power. I haven't tried this on the N800. I would like to see USB charging and USB OTG support made standard. Almost all of the hardware is already in place to do this, but lack of power out on the USB jack prevents it from being turned on. To be USB standard compatible you have to supply some power to the OTG port. Get rid of the Noikia specific changer and move to a USB based one, now I only need to carry one charger for my phone and N800. Freescale has the MC13783 for doing all of this. TI probably has something similar. http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MC13783&nodeId=01J4Fs4881 -- Jon Smirl [EMAIL PROTECTED] ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

Today I tried to read an article on www.theregister.co.uk and this site is unfortunately floating a Flash-based advert over the top of each article. When I went to read one article the N800 browser hung while it tried to display the Flash advert, and after 20 minutes it still hadn't finished displaying the advert. A further 5 minutes of "back" button pressing later succeeded in extricating myself from the page and disabling the Flash plug-in entirely. About 30 minutes later the device shut down because the battery was low!! maps.yahoo.com with flash interface doesn't work www.zillow.com which uses flash doesn't work Neither of these display video. They seem to hang forever. It's not just video where the Flash player is woeful, it's even standard Flash adverts. I wish sites would not use them but they do, the only option is to leave Flash disabled - it may as well not have been shipped with the N800. The Flash player provided with OS 2006 is actually better than the Flash player provided with OS 2007 as the former will not play certain CPU intensive content whereas the latter will play such content and consequently sucks up 100% CPU and hangs the device.

With two power management settings you would specify much longer dim and blanking screen timeout values (perhaps even infinite) when the device is on AC power, but specify short values (perhaps 2 and 5 minutes) when on battery power. There is a significant application area being missed by not having two power settings. When you get to your desk and plug the device in it should, if you configure it to, leave the screen on and run a screen saver type application. This screen saver could work as a clock, music player with album art, show pictures of the kids, show your calendar, etc, etc. This passive behavior should be automatic as soon as the device is plugged into AC. This application area is what chumby, www.chumby.com, is all about.

It would be good if that was only available if the FM radio applet were on the home page, and if removing the applet told you it was reconfiguring any alarms to not use the radio. Just so it's really easy to turn it off, change station, etc when the alarm goes off. I'd like to see FM radio integrated with the Internet radio applet so that there is only one applet on the desktop. This would also allow coordinating muting of the radio streams, FM and Internet appear to be on two different audio paths. If you turn on the Internet radio the FM radio continues to play and is mixed in. That's probably not what you want, but your do want alerts from the desktop mixed in. Alarm functions would be nice. The radio app could also display a large clock when open. The alarm could be made smart too, if Internet or FM were not available it could try the other and then fall back to recorded music just to make sure the alarm is heard. Check out Chumby, http://www.chumby.com/ Chumby is a wifi clock radio that allows you to download various flash applets to customize your experience. It would be very easy to make the N800 emulate the Chumby. There are links to example widgets on the home page. I'd like to see a world clock for an alarm where is shows the current day/night line. Is the N800 smart enough to know when it is on AC and not blank the display? The N770 didn't appear to have this feature. The clock could be set as a screen saver when on AC power. -- Jon Smirl [EMAIL PROTECTED] ___ maemo-users mailing list maemo-users@maemo.org https://maemo.org/mailman/listinfo/maemo-users

I'm not sure how this is relevant since this power injector is meant to provide a tiny amount of current at 5V, just enough to tell the 770 something is plugged in. It doesn't actually power the 770. The OMAP3430 processor has a companion power management chip, the TWL4030. Is this used in the N800? If so, it's spec sheet says that it supports battery charging from USB. Hard to tell how it works with no doc. http://focus.ti.com/general/docs/wtbu/wtbugencontent.tsp?templateId=6123&contentId=4634&DCMP=WTBU&HQS=ProductBulletin+OT+twl4030 Maybe the next Nokia tablet will use something like the Freescale MX31 family which has public documentation. > (Link: > http://thoughtfix.blogspot.com/2006/01/usb-power-injector-2.html) This is > also the same method used by a whole slew of home made ipod and phone > chargers. All the phone chargers I've seen have a significant internal resistance-- they are _not_ designed the same way as devices that charge directly from USB. All the USB phone chargers I've seen have a inline adapter of some sort (including Nokia's new USB charger) to boost the voltage and limit the current. As mentioned, Thoughtfix's injector tells the 770 it has a USB device plugged in and does not power the 770. > > Simon's solution sounds like what I would do. Simon's solution scares me :-) I messed around enough to see how easy it is to start feeding far too much current in very quickly. USB ports are typically current-limited, but it still concerns me.

A Nokia dev mentioned a few days ago that the N800 definitely does *not* support Load the USB gadget driver and it will advertise OTG support. Works on the 770. I don't have an 800 yet. USB OTG. There were also a few threads (not sure if it was here or ITT) mentioning that the kernel included in the N800 firmware does not include the bits necessary to enable USB host mode so there is some doubts that the N800 hardware even supports USB host.

When you plug the USB cable, the Nokia tablets unmount the MMC card so that it could be exported via USB as a block device. It would be *very* annoying if I couldn't play mp3s from the MMC card while the tablet was being charged. Simply charging by USB does not count as an active USB connection. You can charge without unmounting the device. With some creative software you could also remove the need to have only one side using the MMC card. Doing that would probably require exporting the card vs NFS instead of as a USB block device. Plugging in the USB cable could automatically trigger loading/unloading the USB networking module and start the in-kernel NFS server. Another way would be to add a simple UI that pops up when an active USB host is connected. It would just ask if you wanted the MMC exported over USB and give you a chance to say no.

The only way to make it work is to plug a powered hub into the port and then plug the keyboard into the hub. I consider this a significant design flaw in the N800/770. It would really be nice if there was a small amount of power supplied to the USB port, just enough to run a keyboard or memory stick. Less than 100ma at 5V.
