Trying to get USB 2 usefully installed in my old G4. Yeah, I know it's old, but there ain't nothin' wrong with it and other than this issue, I have no reason to upgrade hardware at this time. So I buy a USB 2 pci card (forgot the brand) and installed it, System Profiler sees it, but doesn't see anything connected to it. I figure it might be the port configuration, the connectors touch the case when plugged in. That doesn't seem right, but oh well, that's the way it is. Ok, so now I have a critical project that requires USB 2 connectivity in order to get done this year (an exaggeration - but I can't wait 7 hours each to burn and print DVD's on a rented robotic duplicator - which was tested and works perfectly where it came from). So off to the store I go to try another USB 2 card. This time I get a Q-Store card, which states on it that it's Mac compatible (requires G3/10.2.6/64mb, I have G4/10.4.11/960mb). No problem, right? Wrong. Same thing. System Profiler sees the card but doesn't see the device connected (except for one fleeting instant never to be repeated). I'm at my wits end here. I NEED functional USB 2 on this machine RIGHT NOW and I KNOW it can be done but I have no idea why it doesn't work. I know there are sleep issues with some USB 2 pci cards on this series machine - I don't care about sleep issues. I care about USB 2 that works. I'm open to any and all suggestions toward a solution, barring purchase of a new computer.
