Shouldn't what all be alike? -- all the ports or all the hubs?  Are all 3
of those hubs external units connected to the one port listed by lspci?

What makes you say the hubs aren't initialized properly on startup?

Post it to this mailing list.  Also post the contents of 
/proc/bus/usb/devices after booting with your mouse plugged into one of 
the non-working ports.  And it would help a lot if you can turn on the USB 
verbose debugging switch in your kernel configuration and post the system 
log (or dmesg output) showing the debug messages during the boot 
procedure.

VIA controllers have several problems.  This one is new to me, though 
other people may know about it.

It's impossible to say whether the problem can be worked around in the 
kernel without knowing what the actual problem is!
