Ok, the Ubuntu installation has completed, but USB doesn't work. While it's starting up I get lots of messages that USB devices are being detected, but none of them work. I also get a few of the following messages:
FATAL : could not load /lib/modules/2.6.22-14-powerpc/modules.dep: no such file or directory
Could that stop USB from working? I have a modules.dep file (amongst other things) in /lib/modules/2.6.22-16-powerpc. Can I tell the kernel to use that instead?
