Bug#927247: usbip: qemu destructively resets usbip device

[sg <sgraham@innovaprep.com>]

Package: usbip
Version: 2.0+4.9.144-3.1
Severity: important

Dear Maintainer,

When passing a usbip device to qemu, qemu appears to reenumerate the
device which causes the connection to the usbipd to become upset. The
device is then unavailable for use in the VM or on the usbip client.

The device in question is an HID device and works when passed through on
what is intended to the be the server computer to a VM. Modules were
blacklisted to ensure they did not upset qemu's capture of the device
fds.

Once the VM starts dmesg logs failure to enumerate messages, and
admonishes the user to check the cable.

I apologize for marking the bug as important but it makes the package
useless for my purposes.

Cheers,
   sg
