cat /sys/bus/usb/devices/DEVICE_ID/idVendor cat /sys/bus/usb/devices/DEVICE_ID/idProduct will get you these values (replace DEVICE_ID with your device's id). So in short, you don't need to make a kernel driver function for this, it's already exported to userspace through sysfs. hope this helps, greg k-h ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
