Luis, since it works under the other OS try and break it down to either a difference in USB driver versions or different extensions present. 1) 9.1's USB drivers should be better than 8.6, but perhaps you need to throttle back to 8.6's USB extensions and try it again. Perhaps too the older USB extensions provided with the adapter are better than 9.1's for your purpose. Did the manufacturer's web site offer any help? 2) Here's a wildcard scenario (the extension conflict theory): Some other software could be using resources on the USB bus even though the software itself is not related to any peripheral that uses the USB bus, and this could definitely cause a conflict like you describe. I'm thinking of FaxSTF here. I have a USB burner plugged into an iMac (actually, I've used it with two generations of iMac and both FaxSTF 5.x and FaxSTF 6.x, and the results are the same.) With the fax extensions loaded, the USB bus is weakened. Not by bandwidth of course, but by available resources. Smell the voodoo brewing. The upshot is the burner will make a coaster 2/3 of the way into the burn. It will just forget what it's doing and hang; it isn't a buffer under run or lack of RAM etc.. When I first got it I couldn't leave it plugged in and boot the Mac. I'd get a little farther than a gray screen, but it would freeze every time. When I disable the fax extensions now, my USB chain is great. I found out on either Smith Micro's site or the burner's site (can't remember which) that FaxSTF uses USB resources. I've tried to understand why, but of course they don't explain further and it hurts my brain to try and figure out the idiotic. -David -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
