Hi all,I've bought a simple and cheap USB key/MP3 player by memup.The kernel says:sdc: Write Protect is onHow to disable this write protection?[all details bellow]I use hal/udev/ivman/pmount. When I insert the drive in my gentoo box, it is mounted by ivman/pmount in /media for the current user
# df -T /dev/sdcFilesystem Type 1K-blocks Used Available Use% Mounted on/dev/sdc vfat 251496 1344 250152 1% /media/REGIS_USBdrwx-- 2 regis users 16384 jan 1 1970 /media/REGIS_USB
And /media/REGIS_USB does list the content of the USB drive.Now, I can't write anything on this filesytem.regis /media/REGIS_USB % touch toto
touch: cannot touch `toto': Read-only file systemAs I understand my trivial configuration, this should be mounted read+write. Just in case, I tried:kro64 REGIS_USB # mount -o rw,remount /media/REGIS_USB/
mount: block device /dev/sdc is write-protected, mounting read-onlydmesg saysusb 2-4: USB disconnect, address 2usb 3-4: new full speed USB device using ohci_hcd and address 10usb 3-4: configuration #1 chosen from 1 choice

usb-storage: device scan completeI have another usb key which is mounted rw as expected. The major difference I see is that dmesg says about the other key:sdc: Write Protect is offSo: I do change this Write-protect parameter?
Thanks and merry Easter.-- Régis-- Régis
