The internals are exposed, it's up to your distro to properly hook them up so that you can see them. I suggest that if your distro is somehow keeping you from reading from the usb device nodes in /dev/bus/usb/ that you take it up with them, as that differs from the "standard" that all of the major distros have agreed apon. thanks, greg k-h -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
