I wonder if anyone else has had problems and knows a fix for sleep problems related to the 10.4.7 update when you have a PCI USB 2.0 card and hub installed. On the Apple forums lots of folks seem to be having issues with the same setups. I think most of us with older G4's got the USB cards because Apple changed the connection on the newer iPods from Firewire to USB 2. (That's pretty annoying too but another issue.) I can't put the computer to sleep with the hub attached (it's a brand new Belkin powered 6 plug hub). If I do the computer wakes but it's totally frozen and needs to be restarted hard. It worked fine before I updated to 10.4.7 a couple of weeks ago. I did do the combo update. I have a 350 Sawtooth which I know is an antique but I love it. Thanks for any advice you can give. Greg C.
