forgot to mention that this is an x86_64, pci-e system if its relevant. 

this was also a problem on fedora core 3 with their supplied RPM packages.

Hello, 
 
I get the same problem. Now I have kernel 2.6.10 vanilla using at suse 9.2. 
Hotpulg is 0.45-21. When I boot I get this message about usb:

I don't get any file at /proc/bus/usb and all devices connect to usb doesn't 
work.

i've just spotted the line 

PCI: cache line size of 64 is not supported by device 0000:00:02.1

in dmesg. could this be relevant? 4 of the broken ports are on that bus, though
2 of the remaining ports dont work, while 2 do.

from dmesg:

Comment 4 Greg Kroah-Hartman 2005-02-17 08:57:09 UTC

Can you try 2.6.11-rc4 and see if it's still not working for you there?
If it isn't, please reopen this bug.
