I agree, I'd expect that the camera would almost have to be a full
speed USB device. Low speed USB is a-w-f-u-l-l-y s-l-o-w (i.e.
hundreds of bytes per second). This speed would be painful, especially
for large chunks of data like pictures.

Whether the camera can operate as a low speed USB device or not,
though, the PIC would have to act as the USB host to talk to it. That
aspect of it could get real ugly real fast.=20
