Package: usbip
Version: 2.0+4.9.144-3.1
Severity: normal
Tags: upstream

Dear Maintainer,

Attempting to pass a usbip device to qemu fails. Qemu resets the device
and it does not reappear. Dmesg prompts warn of checking the cable
connection and that the device does not enumerate.

It is suspected qemu reenumerates the device and this causes usbip to
drop the connection but I can not be sure.

The device passes to a VM when done directly.
