USB device is reported as "unknown device" in Windows Guest on Windows Host

Reported by: beamrider Owned by:
Priority: major Component: USB
Version: VirtualBox 3.0.12 Keywords:
Cc: Guest type: Windows
Host type: Windows

Description

The problem appears related to the slash contained in the device serial number. My guess is that the conversion into a # brokens the guest address.

Using "VBoxManage.exe list usbhost":

UUID: d398cf2d-92ee-44bc-aa8e-6ccef37494eb
VendorId: 0x1781 (1781)

SerialNumber: GNU/GPL2

is reported at the guest as:

UUID: fd66cabb-4b08-4a90-a877-468e438c50b4
VendorId: 0x1781 (1781)

The guest os see the device as "unknown device" with PID and VID to 0.

Tried reflashing the device with a different serial number (with a - instead of /) and obtained a regular Address (\?\usb#vid_80ee&pid_cafe#gnu-gpl2#...). Anyway the device is still "unknown" in guest OS.

The device driver in host system is usblib0 (usblib windows port).
