Subject: RE: [PATCH 2/3] testusb: using real device-nodes managed by udev
 instead of using usbfs

I am sorry I haven't consider of that. I just want testusb tool can work with default option since path /dev/bus/usb exists on most computer, not /proc/bus/usb.
So, if I just add /dev/bus/usb to the default search path, is it ok? Thanks.

Why?  Is this causing problems as it is today?

Did you just break scripts that was using that option?  That's not nice, and not acceptable.
