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

| Component: | USB | Version: | VirtualBox 3.0.12 |

Description (last modified by )
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":

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).
