Hey, I've only been able to just get around to setting up my UMDK boards. I've got a fresh install of ubuntu for simplicity sake on a netbook here and I've gone as far as trying to flash the firmware after testing voltages but receive an error in relation to LIBUSB. I'm not sure what really is wrong here. 

After running flcli -i 04b4:8613 -v 1d50:602b

i end up with flLoadStandardFirmware(): usbOpenDevice(): LIBUSB_ERROR ACCESS

It fails at [1] status from this [2].

If you could help us please put some breaks at the start of the usbOpenDevice function and from this we can determine what causes this.
I am not at UMDK presently and will not be this week so it may be faster if you could do this test for us.
Also, have a look at what messages appear from the USB driver and filter for UMDK.

Cheers,
Chris.
