No, it's been happening to me for the past 4 years from 2.4 kernels and still no solution. > Could my hardware be defective? (stick, controller, ??) Probably Linux compatibility with the motherboard/BIOS/USB controller. Happens on some computers, not on others. All versions of Windows from 98 don't have this problem on any hardware. > Is a workaround known? You're not going to like it... use Windows and run Linux through VMware. > What can I do? What should I do? Try a different computer. The USB controller I know doesn't cause problems is the "USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB2 EHCI Controller (rev 03)". > Thanks for any help, > Martin.
