I have a Ratoc CFU1 USB host card for my C860. The driver I am using is cfu1-driver_0.0.2-3 from
I am trying to connect a usb webcam to the PDA. The camera can be detected by the proper driver (e.g. pwc.o for Philips webcam). However if I try to get video from the camera it just suspends. After some debuging I found the problem is that the current driver hc_sl811.o and sl811_cs.o does not support USB isochronous transfer mode.
From the Racto website I read this:
*The CFU1U does not work with the Web Camera using isochronous transfer
But it's really difficult to find a usb webcam that does NOT use isochronous transfer mode.
Could anyone tell me if this can be solved by developing new isochronous-enabled device driver for CFU1, or it's really a hardware limitation of this product? Thanks in advance!
