I upgraded my Rev A iMac from 8.6 last week with no initial problems except I had to do a firmware update before I could run the upgrade. Everything seemed to work fine, including my printer: an original Epson 600 with a USB to Parallel cable and software. Then I got around to hooking up my Palm. The desktop pac works great but when I tried to do a hotsync I was told the port was in use. Checking the Chooser I found that I now had an additional port: USB Printer which was running my Epson. The internal printer/modem port was also there but trying to switch the printer to it brought up the "port in use" message. I've tried unplugging the printer, restarting the computer several times...no help. Anyone have any ideas?
