USB 2.0 to Ethernet Adapter for Razr

I have the Droid Razr running ICS 4.0.4. I have both the Motorola Atrix Lapdock (on which I've modified the pins to accept the Razr) and the Premium HD Station (the one with the additional 3 USB ports). Understandably neither of these two accessories 'supports' Ethernet because they don't have an Ethernet port, but I would think that since both support USB then I should be able to use a USB to Ethernet adapter to achieve Ethernet networking.

I'd purchased an adapter before, but apparently it had the wrong chipset. I could never enable Ethernet. I've seen where ICS supports Ethernet, but the posts have been about tablets or other phones running ICS, not the Razr.

In short, what phone accessories will support Ethernet via a USB adapter (hopefully one or both of my Lapdock and HD Station) and specifically what USB/Ethernet adapter(s) can I purchase that are known to work with the device.

Thank you in advance,
Andrew

I am quite surprised that no one has a definitive answer on whether or not a person can get an Ethernet connection via one of the RAZR docking stations' USB ports.

Thanks,
Andrew
