It's easier to go from a sysfs device to a usbfs device, but I don't understand the question really. You want to know how to do it on newer kernels but not older ones? The mapping is still the same, nothing has changed, you can still just look up the bus and device number from the usbfs name and then walk sysfs to get the device. That will work with all kernel versions, right? thanks, greg k-h ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
