Just tried my HP7400c scanner with the latest cvs from

I am using a Pentium II and UCHI chipset/interface,which  did not work until now.
Althought sometimes I still get the bulk errors/hangs as in:

usbfs: USBDEVFS_BULK failed ep 0x83 len 4096 ret -84

it now basically WORKS!

Thanks for the great work Rene!

But alas, when selecting "Transparancy" (using xsane or xscanimage),
the transparency light goes on and the driver freezes again, ending which
the bulk messages such as above.

I am using kernel 2.6.9 and sane-backends-1.0.15.
