As Georg replied, to see /proc/bus/usb/* you have to mount it:
mount -t usbdevfs usbdevfs /proc/bus/usb
If you've done that and still don't see it, there's a patch
for it below.
Nemosoft discovered this Philips audio or a similar problem in
March/2000 and posted
http://electricrain.com/lists/archive/linux-usb/2000/03/msg00832.html
and
http://electricrain.com/lists/archive/linux-usb/2000/03/msg00850.html
The second one is a patch against 2.3.51 and is in kernels after
2.3.99-pre3 (or so), so it's not included in the 2.3.50-pre1
backport patch. However, this problem could already be fixed.
For /proc/bus/usb/devices showing up empty after it is
mounted, Mike Harris posted a patch for this (mangled by
email) and I reposted it last Thu/2000-apr-13.
It's also available at linux-usb.sourceforge.net, under
Patch Manager, Patch ID = 100257. This patch applies
after the 2.3.50-pre1 backport patch.
Vojtech, are you considering updating the backport patch?
