[Qemu-devel] [Bug 1247796] [NEW] USB Passthrough not working for Windows 7 Embedded guest

[Jens Frederich]

Public bug reported:

USB Passthrough from host to guest is not working for a 32-bit Windows 7
guest.

The device appears in the device manager of Windows 7, but with "Error
code 10: device cannot start". I have tried this with numerous USB
thumbdrives and a USB wireless NIC, all with the same result. The device
name and functionality is recognized, so at least some USB negotiation
is taking place.
