ethernet controller. The driver has been tested with the LinkSys USB200M adapter. I know for a fact that there are other devices out there with this chip but don't have all the USB vendor/device IDs. Note: I'm not sure if this will force the driver to end up in the install kernel image or not. Special magic needs to be done to exclude it to keep the boot floppies from bloating again, someone please advise.

|
|

|
|
* represents the direction (0 for vendor read, 1 for vendor write).
|
|
* CC is the command byte, as specified in the manual.
