The message is not absolutly correct. Devices have address 0 during intialisation and since this is the case it's absolutely correct. However under normal conditions this is the case for a short period of time. > Followed shortly by this message on the console: > > uhub0: device problem, disabling port 2 OK - we have a problem, but we don't know which :( Add USB_DEBUG to your kernel and you should get more data out of this case. > If I boot with the device attached, 'usbdevs -v' pauses for quite > a long time and gives the correct probe line: > > [brane-dead] ~ # usbdevs -v > Controller /dev/usb0: > addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00 > port 1 powered > port 2 addr 2: full speed, power 500 mA, config 1, Flash Reader(0xa600), DATAFAB(0x07c4), rev 1.19 Interesting. > However, the device is still unusable. Mmm - but usbdevs gets it's data by directly talking to the device, so everytime you invoke usbdevs the device is involved.
