Can you give an exact output (maybe last 10 lines) of the error?

Did you do lsusb, did it give something like

mymachine:~ # lsusb
Bus 023 Device 042: ID 7070:1234

Did it say "no USB device" or some other error? Sometimes access rights
are an issue, use the files in conf/system.

You should get some debug info with 115200 8N1 on the serial if you
start the bootloader.
