#1 Re: Card Readers and USB keys using udev Posted by Anonymous (212.135.xx.xx) on Thu 5 May 2005 at 18:59 One problem with this is when you have a card reader that provides no notification to the kernel of media insertion events. So, when you plug the card reader in, udev happily creates /dev/sd_reader, but when you subsequently plug a card into the reader, the kernel doesn't see it, and you can't mount /dev/sd_reader1 until the kernel has re-scanned the partition table. You can solve this with a udev rule like this:- BUS="usb", KERNEL="sd*", SYSFS{manufacturer}="SanDisk Corporation", SYSFS{product}="ImageMate CompactFlash USB", NAME="sandisk_cf%n", OPTIONS="all_partitions" The "all_partitions" bit makes udev create device nodes for all possible partitions on the device, so when you plug a card in and try to mount /dev/sd_reader1, the kernel sees a read on a non-existent device and re-scans the partition table for you, making the mount work. This makes handling dumb card readers much nicer, though you do get a few extraneous device nodes.
