Hi I'm coming from an ubuntu background where this line in the udev.rule file worked. SUBSYSTEMS=="usb", ATTR{idVendor}=="0fd1", ATTR{idProduct}=="1000", ATTR{bConfigurationValue}=="1",RUN+="/bin/bash -c 'echo 3 > /sys/bus/usb/devices/%b/bConfigurationValue'" However this does not work in Arch and I'm really struggling to understand the udev wiki and udev rules - its going a bit over my head at the moment. I have experimented with trying this line from looking at other udev rules: SUBSYSTEM=="usb", SYSFS{idProduct}=="1000", SYSFS{idVendor}=="0fd1", RUN+="/bin/bash -c 'echo 3 > /sys/bus/usb/devices/%b/bConfigurationValue'" the device is then recognised but /var/log/messages then shows and endless looping of the device be connected and disconnected. I'm not sure what to do. Please can someone help? M Sent via my BlackBerry from Vodacom - let your email find you!
