Hi All,

I am having a USB CDC ethernet device whose driver exists only for
Linux. However, my end application needs to run on Windows. So, I have
set up Ubuntu 11.10 on Virtual Box running on Windows-7. Ubuntu is
able to register the device but not able to open an interface for it,
say eth1, etc.

[ ?382.531901] usb 2-1: new full speed USB device number 4 using uhci_hcd

My device is "Bus 002 Device 004". How to enable USB CDC ethernet on
this device and expose this interface to Windows using a loop-back
adapter. Any solution on VMware would also be helpful.

Any inputs about what might be the problem. I am able to register the
device perfectly on standalone Linux machine but on Linux running on
Virtual box, USB CDC ethernet device is not able to register. Any help
would be greatly appreciated.
