I'm having a weird problem with my Motorola SURFboard Cable Modem SB5100 connected through USB (uses eth0). I'm dual booting Fedora Core 2 and WinXP. My cable modem only works if I reboot from Windows and then boot Fedora. Otherwise, if I just reboot Fedora, it hangs when trying to bring up eth0. Same applies to shutting down the system.
Another distro I tried, Kanotix BH7 (HD install), had the same problem, except I could use Ctrl+C on boot to make it ignore eth0.
The modem uses the usbnet module on 2.6 kernels and CDCEther on 2.4 kernels. I believe it's a problem in usbnet, as the only distro I got my modem to work flawlessly was Knoppix 3.4 (HD install), which uses the 2.4 kernel. Unfortunately, Knoppix isn't very good as a HD install, so I wanted to try something different
I tried connecting it through ethernet too, but it didn't work with two different Realtek cards.
I would be very grateful if someone could help me get the modem to work through USB.
