I have a Microsoft USB Trackerball which worked perfectly for several years with my old motherboard (a Gigabyte GA-7VAXP). Unfortunately, the old mobo blew itself up last week and I was forced to look for a replacement. Not wishing to buy a new processor, SATA drives, new memory or a new graphics card I decided to look for something similar to my old Gigabyte mobo. This morning I came across an Asus A7V8X-X which uses the same chipset and has broadly similar features.

The new mobo is now installed and everything seems to work - apart from the USB Trackerball...! If I "hot plug" it into any of the 4 available sockets, it will work for about 3 seconds, then it freezes. Similarly, if I boot up with the Trackerball plugged in, it works for about 20-30 seconds, then freezes. I've tried uninstalling the driver and re-booting but it makes no difference. The only obvious difference between the motherboards is that my old one had USB 1.1 and this is USB 2.0.

Are there any known problems with Microsoft Trackerballs and USB 2.0 - or can anyone suggest something else I could try?
