I have been trying to get the packet-writing drivers to work with Red Hat 9 and have so far been unable. I'm using kernel 2.4.20-13.9. I patched it with the 2.4.20-2 patch which required a few minor modifications. I am following the very helpful document from Richard Downing [http://hints.linuxfromscratch.org/hints/cdrw-hint.txt]. Everything seems fine until I actually try to mount a udf disk with mount /dev/pktcdvd0 /mnt/cdrom -t udf -o rw,noatime The drive seeks around, blinks the light and such for almost 5 minutes and then I get: mount: /dev/pktcdvd0: can't read superblock During this time, apparently several messages get sent to the system log as I see with dmesg about 44 lines of: usb-uhci.c: interrupt, status 3, frame# 1745 Where the frame can be any number less than 2000. After those lines, dmesg ends with: failed get_disc pktcdvd: pktcdvd0 failed probe I would be enormously grateful if anyone could offer any assistance for helping me to understand and fix this problem. Thank you, Thane Heninger Iomega
