Has anyone experienced this. I have RHES3 on a dell 2850. I have connected 4 Toshiba dvd readers through a usb hub, and configured hotplug. All devices look to be created and I can access the first 3, but the 4 fails with "no medium found".
--/etc/fstab entries-- /dev/cdrom1 /mnt/cdrom1 udf,iso9660 noauto,owner,kudzu,ro 0 0 /dev/cdrom2 /mnt/cdrom2 udf,iso9660 noauto,owner,kudzu,ro 0 0 /dev/cdrom3 /mnt/cdrom3 udf,iso9660 noauto,owner,kudzu,ro 0 0 /dev/cdrom4 /mnt/cdrom4 udf,iso9660 noauto,owner,kudzu,ro 0 0 The dmesg shows from when I plug the hub in. It detects all 4 cdroms, but when I try to mount /mnt/cdrom4 I get the "cdrom: open failed". I then mount the other 3 cdroms with no problem. --dmesg output-- hub.c: new USB device 00:1d.2-2, assigned address 7 hub.c: USB hub found hub.c: 4 ports detected hub.c: new USB device 00:1d.2-2.1, assigned address 8 WARNING: USB Mass Storage data integrity not assured USB Mass Storage device found at 8 hub.c: new USB device 00:1d.2-2.2, assigned address 9 WARNING: USB Mass Storage data integrity not assured USB Mass Storage device found at 9 hub.c: new USB device 00:1d.2-2.3, assigned address 10 WARNING: USB Mass Storage data integrity not assured USB Mass Storage device found at 10 hub.c: new USB device 00:1d.2-2.4, assigned address 11 WARNING: USB Mass Storage data integrity not assured USB Mass Storage device found at 11 udf: registering filesystem cdrom: open failed. cdrom: open failed.
