In addition to my USB keyboard and mouse, I am running a Happ USB trackball, Tornado USB spinner, OptiPac in USB mode and a dual strike hack. I have a Logitech 4 port USB1.1 hub. Unfortunately, the trackball and spinner tend to cut out after a few minutes of use. I've read some old posts about setting the bios to 1.1 but this does not fix the problem plus I have a USB 2 flash drive that I use daily. The computer is XP SP2 with a 3GHz CPU. I'm thinking I need a new hub. Any recommendations?
