Hi, I did more tests and I was wrong about "broken". It seems more a time-out problem, ie if I try to use sane again in short intervalls, I will get my device working. The cause seems CONFIG_USB_SUSPEND=y. With 2.6.20-rc5 the situation seems better, ie now I don't get "no device" very less often. So do you still want me to try above stuff? -- (°= =°) //\ Prakash Punnoor /\\ V_/ \_V
