I recently had cause to run an old/cheap oscilloscope with software
usb over ethernet using usbip on Linux[1].  This worked well as an
ad hoc setup which I only needed for an afternoon.

However, even in that time it was obvious that re-connection,
or recovery from USB device reset, are not handled well.
I had to manually unbind/re-bind, and restart my application, each
time to get things working again.  I wouldn't want to try to keep
a setup like this running for an extended period.

[1] as in 'apt-get install usbip'
