SUSE Linux Enterprise Server 11
dmesg command output and messages in /var/log/messages shows output similar to:
usb 1-6: device not accepting address 4, error -71
hub 1-0:1.0: unable to enumerate USB device on port 6
Before implementing the permanent fix, it is suggested that you test it first. Unplug your USB device, and then run,
echo -1> /sys/module/usbcore/parameters/autosuspend
Plug your USB device in. If it is detected then continue on to the permenant fix.
The autosuspend setting can be set at the loading of the USB module. The control of device parameters can be found in /etc/modprobe.conf, /etc/modprobe.conf.local and /etc/modprobe.d.
- Create a file in /etc/modprobe.d called usbcore
- Populate the file with the following
options usbcore autosuspend=-1
- Save the file
- Run "mkinitrd" (If you are sure that no USB device modules are loaded via the initrd, then you can skip this step)
