[Bug 507824] Re: Linux kernel 2.6.31-18 in Kubuntu 9.10 Karmic Koala doesn't support usbfs.

[edonia]

Thank you Maxim.
It is not a long term solution, but I found another solution, for getting /proc/bus/usb back again and no need for usbfs.

First I put my user to sudoers for /bin/mount and /bin/umount
Then I changed my scanner script to do the magic.

Before running my scanner the script will do:
sudo mount --bind /dev/bus /proc/bus  

while on exit of the script it fires the command:
sudo umount -l /proc/bus

mount --bind /dev/bus /proc/bus  or
mount --bind /dev/bus/usb /proc/bus/usb
will make /proc/bus/usb accessible /proc/bus/usb for some hardware  (although this will cause the other directories under /proc/bus to be hidden). So you should umount again, after use.
