I had some bother with my USB cable modem with my Mandrake 9.2
install, but I found that Knoppix would load from the CD and recognise
it straight away without my intervention, so my advice is try it and see!
If it helps, here are the steps I took to get my USB modem working
1) at a command line, check the output of
- a list of kernel modules loaded. USB support is via usb-ohci or usb-uhci
or something like that.
2) I needed the appropriate module to work the modem,
which is, for kernel 2.4.x
or for kernel 2.6.x,
If this is not present, it can be loaded; as root, I typed the instruction;
where module-name = CDCEther or usbnet, as appropriate.
(How do I know which kernel I have? Type;
at a command-line)
After doing this I could use Mandrake to get on-line, but sometimes
it was a bit flaky. So I went to;
3) I unplugged the USB cable at both ends & plugged in an ethernet
cable using the optional ethernet port on the modem. I then powered
down the modem & switched it back on, and re-booted theOS.
The connection has been rock solid. I don't know if this is possible with
your Prolink, but it's worth considering.
A potted history which I hope has been useful.
