Help with udev and usb stick

ProtoformX · 04-26-2006, 08:28 AM

Hey guys, it's been a while! Anyways what I am trying to do is to have udev assign my usb stick to a static device block so when I mount my devices via fstab I don't have to guess what device is the usb stick, I have a couple devices that can be considered as mass storage devices and it sometimes gets confusing when I want to know what device is what after they have been pulled out and plugged back in.

Does anyone have any rules I can use that will do this?

Thanks.

Check out the following link - i've used it to make appropriate static device links for quite a few devices (usb stick, camera, removable hard drive)

For mine I made udev rules to create automatic symlinks because of how the kernel device names can change. Try something like this

BUS="USB", SYSFS{Product}="***", NAME="%k", SYMLINK="JumpDrive"

*** is the name of the device as the kernel detects it. Two easy ways to find it are:
the output of dmesg
udevinfo -a -p $(udevinfo -q path -n /dev/sda)

The doc that yuchai pointed you to is very good.
