Yes I did have the same problem in my home's router a while ago. I solved this by changing the value in /sys/bus/usb/devices/3-2/bConfigurationValue which was initially 0 to 1. the OP could possibly wrap this value nicely in ifup so to speak. $ echo -n 1 > /sys/bus/usb/devices/3-2/bConfigurationValue; IMO this happens everytime theres a power shortage. hth -- Cheers, Ishwor Gurung /* humpty dumpty */ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
