(With mouse plugged into the pc) I unplugged the hub and reconnected, 
followed by doing the same for the joystick and printer. Made no 
difference to the lsusb output.

/var/log/message entried found afterwards:

Sep 24 17:15:37 garyh kernel: hub.c: new USB device 00:1d.7-3, assigned 
address 4
Sep 24 17:15:37 garyh kernel: usb.c: USB device not accepting new 
address=4 (error=-71)

Happens when the hub is plugged in.

[root at garyh root]# lspci | grep -i usb

I tried different sockets on the PC with no effect.

Tried this, but didn't make any difference.  The only /var/log/messages 
were when I unplugged/plugged the hub.

The hub is powered.  PLus, if that's the problem I'd expect to have 
problems in XP too.
