Hi All, When a usb mass-storage is attached for the first time, it gets a device (/dev/sda). When it is mounted and the device is manually removed and then when it is attached again, it gets a different name ie /dev/sdb. This is because earlier the mass-storage device was removed (manually) when it was mounted, so scsi_disk_release() did not get called as the device (sda) had a reference count > 1. So, if my understanding is correct, I would like to know if the above mentioned behaviour is a bug or a limitation of the kernel? Regards, Ayan Kumar Halder
