Hi Last night 'lsusb' command gave me a headache. I have been using SuSE 9.2 (stock kernel, YOU - nothing special) for months. After entering (almost by accident) 'lsusb' my older Acer Power SC computer stuck - crashed completely. To be as short as possible: lsusb - crashes computer lsdev - OK usbview - OK sane-find-scanner - I have to plug off my box hwscan --usb - gives me nothing (at least the crash does not occur) If I enter 'lsusb' remotely (via ssh) then it works, but 'sane-find-scanner' (also via ssh) freezes my box. Then I decided to plug in USB mouse and USB keyboard instead of PS/2 ones. It works. Then I tried my Sony DSC-P72. Again no problem. USB is working. The ' cat /proc/bus/usb/devices' reveals all. I have tried 'noapic, acpi=off'. In BIOS I switched 'USB legacy mode'. Always the same sad story. At work I have repeated the same steps on the same model and with SuSE 9.2. The system froze. With SuSE 9.0 on the same model everything is working. With newer Acer model (Power F1), 'lsusb' works. Well it is time to give 9.3 a try. Once upon a time there was a SuSE sentence 'Have a fun'. Does anybody has just a little clue (not to mention that W2K are OK as far as USB is concerned) ?? Regards Zvone Zagar
