Correct. usbfs has been removed in 2.6.31.

It's strange that lsusb no longer works for you. I've verified that on 
Debian stable (Lenny) it does still work after I unmount /proc/bus/usb.
I guess Debian must have a newer version of usbutils, or one built with 
libusb support.

The fact that your USB devices work means they do have libusb support.

$ dpkg -l usbutils
ii  usbutils        0.73-10         Linux USB utilities

Note that /proc/bus/usb/devices has been moved to debugfs and there's also 
work being done (see linux-usb archive) on a script that can list 
equivalent info by walking /sys.

For all the above: AFAIK and IIUC :-)

Cheers,
FJP
