Hi there, After I installed a Keyspan U2PCI-5 USB 2.0 card my G4 450 AGP (Sawtooth) running OS 10.3.5 won't wake from sleep (unless I do a forced restart) after putting it to sleep. On its own, it just won't go to sleep at all now (fan runs and power light stays green, not amber). If nothing is plugged into card, then no problems. Otherwise, problems. This defeats the purpose of the new high speed card since the built in is only USB 1.0. Does anyone know of a USB 2.0 card that will work on a G4 AGP (Sawtooth) without these problems? If so, I would be eternally gratefull! Thanks. Casey.
