I just tried it on a fourth computer and still no luck. XP Laptop - unknown device. Customer's iMac - USB doesn't even recognize it. My iMac running XP - USB doesn't even recognize it. My desktop PC running XP - unknown device.

I've done 880's before ON THE SAME LAPTOP. Why in the world would it suddenly be an issue?

I did try a different USB cable. I'm pretty sure it's a bad USB port on the remote.

But - the last remote I was convinced was broken was a T3-V and it turned out the screen just wasn't calibrated right.... (wouldn't exit out of the screen calibration screen after trying for 30 minutes...until I got it to the office then on the first try it went right through...)

edit - hey, this was my 3,000th post!
