From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1) Gecko/20020827 Description of problem: We have a usb attached flash card reader for reading various flash cards from digital cameras, varying in size from 64mb to 640mb. Inserting a card and mounting it as /dev/sda1 works ok, unmounting and unplugging also ok, then if i insert a card with a different geometry, mount complains about invalid partition table and fdisk -l /dev/sda shows garbage. I haven't found a way around this other than rmmod usb-storage. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.modprobe usb-storage 2.mount /dev/sda1 /mnt 3.some ls, cp, rm on /mnt 4. umount /mnt 5. remove flash card from reader 6. insert different flash card into reader 7. mount /dev/sda1 /mnt Actual Results: mount: wrong fs type, bad option, bad superblock on /dev/sda1, or too many mounted file systems fdisk -l /dev/sda at this time shows partition of weird types, partitions with incorrect boundries and similiar 'interesting' things. Expected Results: usb-storage should adapt the new geometry of the card and read it properly. Additional info: When running this on redhat 7.0 with 2.4.2 or 2.4.5-ac13 kernels this worked ok. Now on 7.3 with 2.4.18-10 this does not work anymore. There' was either some bug introduced in the usb-storage or i'm doing something wrong. The only way to fix this problem is to rmmod and modprobe usb-storage, wich requires root privileges and is not solvable by the user. So this is a major support nightmare right now ...
http://www.uwsg.iu.edu/hypermail/linux/kernel/0110.2/1043.html i found this suggestion ... will try it out in the following days.
I have the same problem on RedHat 8.0 with Kernel 2.4.20-20 and I found useful rmmod usb-storage when I have to change the device.
I don't think it's the maxusage. In case of Jure, 90% is that it was fixed. For Michele, I need /proc/bus/usb/devices captured to see what kind of device it is, it might need a workaround.
No reply from Jure - closing. A bug has to be filed again if FC1 or FC2 have this problem.
