But I received another email saying that USB scanner worked. I am confused 
about this. Anyways this is what I have

Then my scanner was detected.

Not yet.

Any ideas or pointers on how to get ugen0 to be configured? What kernel 
code for that? I read "The ugen driver provides support for all USB 
devices that do not have a special driver." So it seems like I shouldn't 
have to do anything special to have a ugen0 (booting with 4.0 kernel 
instead of my custom built kernel for uscanner supporting the device).


Well I heard from one person that USB scanner worked when they commented 
out the uscanner kernel configuration. Is that applicable even if uscanner 
doesn't know about the hardware? (I should try instead of asking but 
rebooting many times is slow!)
