I am having similar problems with FC1 and the usb mass-storage module. I have an external USB HP 4X cd-rw drive. When I first plug it in, usb-storage is loaded. Running cdrecord -scanbus shows it as device 0,0,0. Then I burn a CD and it comes out fine. However, when I try to burn a second cd, cdrecord pukes with errors. Running cdrecord -scanbus again, shows device 0,0,0 but in the description field I get all kinds of funky characters. So i do rmmod usb-storage, unplug the cd-rw and plug it back in and the system hangs. If I do rmmod usb-storage and leave the cd-rw plugged in and try to modprobe usb-storage, the system hangs. If I do rmmod usb-storage, unplug the cd-rw, do modprobe usb-storage and then plug the cd-rw back in, the system hangs. The only way I can burn two cd's in a row is to reboot! I guess I could try to remove all the usb related modules, though my keyboard and mouse both come in over one usb cable from a Belkin 4 port switch. I didn't notice this behavior when I was using the same USB cd-rw drive under RH9. Jim Drabb -- James Drabb Senior Programmer Analyst Davenport, FL USA
