Hello all, i restart this thread, as until now, i didn't got it up and working. Thx for any help before. i have the following hw-config: -compaq proliant, 500 mhz, 256 mb ram, fedora core 1 installed, with 2-port-usb-card port 1: USB-Printer HP PSC750 - works fine! port 2: HID interface, works sometimes if i disconnect and reconnect, but only if it likes to on this compaq. works fine on other (fedora-)servers. what do you need for a real good analysis? just tell, as this is the only thing not working on this machine... cheers, Roger
