I have been experimenting with a Microtech USB CameraMate (DPCM) on
a P-II/PIIX laptop with Linux-2.4.5 and all relevant drivers
(including UHCI-alt and DPCM) turned on. The device is recognized,
but I have never got any I/O on any storage device plugged into it.
Mostly I have been using an Olympus 8M 3v SmartMedia card. According
to Microtech's web site you are supposed to plug in the SM card after
the DPCM is plugged in, and and unplug the card before unplugging
the DPCM.
I have attached below all the logs & reports that seem relevant.
Clue?
