From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.2; Linux) (KHTML, like Gecko) Description of problem: When I boot up fedora core 2 with a USB mouse plugged in then the touchpad no longer works. However, if I reboot with the USB mouse not connected the touchpad does work (although tapping on touchpad does not simulate mouse click). In fedora core 1 they both worked together. I could use the touchpad and USB mouse without having to reboot the computer. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Turn on computer with USB mouse plugged in 2. 3. Actual Results: Touchpad no longer functions Expected Results: Touchpad and USB mouse should work together. Also should be able to tap on touchpad to simulate a mouse click. Additional info:
If your BIOS has an option for "USB legacy emulation" or anything of that sort, try disabling it. That won't make touchpad tapping work (see bug 116091 and bug 122014 for more information), but it might allow the touchpad and the USB mouse to work together. If you can't find such an option, you may want to try plugging the USB mouse in after the system finishes booting.
Regarding the touchpad tapping again, you may also want to look at bug 123529.
The problem seems to be fixed in later versions of the kernel. I have tried a few now and have not reencountered the problem.
reassigning to kernel component and closing as ERRATA
