I see. So under Suse 10.3, you see different results of d.bus and dev.bus[0].dirname without your patch, right? In my case, the values are the same. So it will still match with your patch. On the other hand, the code does not print out anything under my Mac Mini which runs Mac OS X Lion, but that is probably a separate issue. -- Xiaofan ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
