Yes this is enough.

There are two issues that we need to investigate in order to resolve this:

1. What is the error occuring in the first place
2. Which component is not handling this failure correctly

For 1 enabling UsbDk tracing can give us a bigger picture on what's causing
this error, please refer to the following link for instructions on tracing
UsbDk:
https://github.com/daynix/UsbDk/blob/master/Documentation/Tracing.txt

For 2 It could be the usbredir (https://cgit.freedesktop.org/spice/usbredir)
component failing to handle libusb failures. I am not that familiar with
the usbredir code,
but inserting few debug prints in the main loop should give a good idea
where this bug lies.

Please do send traces back so we can further investigate the issue =)
