USB CDC ethernet interface from Ubuntu on VirtualBox to Windows 7

USB CDC ethernet interface from Ubuntu on VirtualBox to Windows 7

[Manavendra Nath Manav]

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 at 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 at 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.

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.

Okay, I will post in Virtual box mailing list too. Just a small query,
what does "[usb probe] failed with error -32" means here? I am just
curious to know can we reverse engineer the root cause by looking at
this error.
