USB diver not workig properly (MIDISPORT 2*2)

[avril.stephane]

Hi,

I'm using Windows XP pro under Mandriva 2007.1 with VirtualBox 1.4.
I would like to use a usb Midisport under windows.
But after installation, the driver does not work properly (only one "USB audio Port")
and it sould be 2 ports : USB Audio Port A and anoher port B (2*2).
When I plug the USB audio material nothing happen, it should have the installation assistant.
I have the same Windows XP PRO installed in another partition,
and the driver works properly when I boot on Windows.

If anyone has an idea !
thanks in advance,

Stéphane
