"it starts locking up for about half a second to a few seconds at a time."
This is the usually EMI-problem ("sparking" switches, etc). Sporadically
disconnected by the hub and then reconnected. No mouse for a few seconds,
but it should work again. Blame the hub hardware designers for that. I have
a hub where even the connection of an unloaded cable with the hub's port
shielding causes the disconnection of all devices on the hub...

"but under SuSE Linux 6.4 (Kernel 2.2.14) the USB system seems to hang the mouse"
Stoneage, could be anything, neither usb-uhci nor uhci existed in those
days.

"just have to detach and reattach it after a suspend sometimes"
Could be a power management problem (kernel 2.2.18) and/or a too small hub
delay after power on. There's a more forgiving device detection in the
latest kernels that should fix these timeouts.
So those quotes don't tell too much about your problem. Usually 99% of all
problems in USB show the same symptoms: Device doesn't work...
