Re: [Elecraft] Can not connect KIO3B USB with my MacMini
Open up a terminal window and type: ls -l /dev/tty.usb* You should see something like this: (the serial number will differ) crw-rw-rw- 1 root wheel 19, 0 Feb 25 13:13 /dev/tty.usbserial-A567JW3P If you're seeing that, then you should then be able tobring up the K3 Utility and "talk" to the K3. I just installedmy KIO3B about a month ago, and I'm running MacOS Sierra 10.12.3on a early 2015 13" Retina MacBook Pro. Under my "System Report",I see my USB disk (used for Time Machine) and the built-in BluetoothController plugged into the "USB 3.0 Bus", and then below that, Isee a "General Purpose USB Hub" as the next item plugged into the 3.0bus, and attached to the GP bus, I have a USB Audio CODEC and anFT232R USB UART. The CODEC is a TI device and it's reporting that 500mA is availableto it, and it's requiring 0mA. The FTDI FT232R UART is likewisereporting 500mA available to it, and it's drawing 90mA. Since the"hub" is inside the KIO3B and being powered by it, it should notbe causing the USB power complaint you're getting on the Mini. BUT,since the Mini is an older device, it is probably USB2, not USB3,and can't source as much current, etc., and its circuitry *may* besomewhat intolerant of sudden changes. (I've had problems with blowingexternally powered USB2 hubs, apparently caused by hot un/plugging,resulting in MacOS reporting devices seen that Parallels and Windowswould/could not talk to. I've now switched to the KIO3B and I'm notgoing to do any hot un/plugging, just to be on the safe side.) In fact, you might want to see if you can troubleshoot your problemby shutting everything down and powering it all down, configuring yourcabling, and then powering it all back up and booting it up. I knowit sounds like a nuisance, but it may give you a valuable indication. HTH, and 73, Bayard R.

Re: [Elecraft] Can not connect KIO3B USB with my MacMini
From the K3S manual, p. 18: *Set the CONFIG:RS232 menu parameter to USB. Exit the menu.* • With the USB cable plugged in and the K3S turned on, determine which COM or sound device ports have been assigned to the K3S. This can be done from within applications. On Windows PCs, an alternative is to locate the Device Manager (Start > Control Panel > System > Hardware), and view its list of Ports. When you plug in the USB cable from the K3S, a new COM port will appear in the list. If you don't have this item set, the K3 won't recognize the USB connection and will be expecting a serial port connection. In your MAC look for new connections after you set CONFIG:RS232 to USB. If it's already at USB and won't recognize, then you need to call Elecraft tech support. 73, Guy On Sat, Feb 25, 2017 at 1:42 PM, PHILIP GRAITCERwrote: > I am unable to connect the USB on my K3, modified with a KIO3B set of > boards, to my MacMini, running OS10.9.5.
