As I can't use the SDDR-31 either, it would be a dramatic improvement if I could get that working. But I'd most like to find a USB-2 reader that works, because the files my camera writes are huge... > This is not good, because -71 is a low-level protocol error.

It also has a brand new AMD 3200/400 CPU and brand new RAM. And I've tried two different power supplies, just for kicks. There are no hubs involved, I plug the CF readers directly into the onboard USB. So yeah, I've already run so far out of ideas that I've gone down the "replace absolutely everything" path. Hell, the *disks* are only a few months older than the rest of the machine. The only other peripheral plugged into the machine at all is the video card (Nvidia 5700 Ultra). > To be frank, it is possible for the software to report -71 for a bad > reason, when it is confused.

Ok, what other info would help? > BTW, I should note that it is possible to use a passive PCMCIA-CF adapter. I've used those succesfully in laptops, and consequently (a few years ago) I tried to get two different models of PCMCIA bay installed in my desktop machine to avoid USB entirely, but that was an even bigger disaster. -- Jamie Zawinski jwz@xxxxxxx http://www.jwz.org/ jwz@xxxxxxxxxxxxx http://www.dnalounge.com/ http://jwz.livejournal.com/
