Interesting - the port is disabled and then you get the ugen message.
Are you shure that these messages belong together?
If the device really refuses set_config it is a very fundamental
USB violation.

I would like to know if the device is still processing requests.
What does usbdevs -v say?
usbdevs -v asks the device to descriptor string, so we will know if
is is running.
A hang device would hang output of usbdevs at a given for a few seconds
until timeout.
