I read the UDEV Primer and I'm still confused

[Javasnob]

Hi everybody,

Ever since I moved to a 2.6 kernel (and therefore udev), I haven't been able to access my USB flash drive. It used to be /dev/sda, and my harddrive was /dev/hda. Now my harddrive is /dev/sda, and I don't know where to look for it. I've gone over /sys/bus/usb, but under devices there, there's 5 usb devices. How do I know which one is the right one, and where is the device to mount?

Thanks!

Try /dev/sda1 when your usb_storage module is loaded (and the necessary scsi support). This happens (dmesg) when I plugin an usbstick:

I don't think that'll work, considering that my harddrive (an SATA) is at /dev/sda.

If /dev/sda stands for your hard drive then, usb flash drive should be accessible by /dev/sdb or /dev/sdc ! Try it and lemme know if this works.

No go; none of them are valid block devices.
