The patch below adds support for the KC2190 usb-to-usb networking
device; the version I have reports itself as:
Bus 001 Device 003: ID 050f:0190 KC Technology, Inc.
I was under the impression that support for this had been added a long
time ago, but searching through old kernel versions all I could find was
a comment about the chip, with no support. Patch is against 2.6.9 but is
pretty minimal.
I don't have a Windows box around to test interoperability with that
driver, but the patch appears to make it work perfectly between 2 Linux
boxes.
