Hi,

This may interest some of you:

I've got an agfa snapscan USB scanner (uses USB 1.1 OHCI, the module is ohci_hcd with a 2.6 kernel) and I couldn't get it work after I upgraded from kernel 2.6.7 to 2.6.8.1 or above.

I still could see device connection or disconnection in /var/log/messages.

The fact is that USB support has been rewritten between these two versions, and there were misconfiguration in /dev for 2.6.8.1 to correctly handle the USB device.

The solution was to use the

Code:

/sbin/MAKEDEV usb

command, but executed from /dev or it would create character devices at the wrong place :p
