USB CDC ethernet interface from Ubuntu on VirtualBox to Windows 7

[Manavendra Nath Manav <mnm.kernel@xxxxxxxxx>]

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
[  392.992690] cdc_ether: probe of 2-1:2.0 failed with error -32

e518816@ubuntu:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
Bus 002 Device 004: ID 0e1e:0800
e518816@ubuntu:~$

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.
