Dear Greg and Dave,
Thanks for your mails, both of you, and for your advice about how to submit
the patch, Greg. It feels welcoming for me as a kernel newbie.
I agree with you Dave that usbnet comes up quite easily once the correct
VID and PID are put in plusb.c. However, once I got two machines working
like this, I could not ping across the link yet.
I also downloaded and ran the USB test suite from the USB specification
body, and this seemed to show some issues, especially with the maximum
packet size, in the device.
- Do you know where I can set this in the usbnet system please?
So more work is required to get it working. More details below for your
info.
Please let me know what you think. Any comments gratefully received.
Kind Regards,
Tony
---Detailed info--------------
One of the laptops was running Ubuntu Dapper Drake distro with the
2.6.17.14 kernel with uhci_hcd, along with my Fedora core 8 running
2.6.23.14-107 and using ehci_hcd.
The dmesg logs showed the following:

Yes ... but make sure it does more than just provide a "usb0"
interface. That's pretty much a given once you stick its IDs
in one of those files. Does it pass packets OK, both directions?
And those particular patches should go to netdev, by the way.
