Yes, it can. Looking at the usb traces, it looks like it is very close, if not 
identical, to a gl646. The registers used are the same, and the method to access 
them is very similar to that of the gl640.

It seems there is at least 3 hp usb scanners (3670, 3690, 2400) that have a 
close chip. I'm only sure about the 3670 since that's the only one I found usb 
traces.

Is it possible you set up a cvs tree for backends development (not specific to a 
particular backend) and a mailing list for people interrested in the GL 
scanner-on-chip dev? I don't want to use SF, and it would be better on alioth 
anyway.
If you don't mind, I'd also like to see what code you have written for the gl646.

Frank.
