Re: [gentoo-user] No /dev/sda1 with Klingston usb disk. Wrong lsusb output.

[Konstantin V. Gavrilenko]

I noticed similar behavior on the externally connected usb storage devices.

On the example of the SD card reader, when you insert the card, /dev/sdb
appears, but not the actual partition (/dev/sdb1)

So you have to do fdisk /dev/sdb, then quit, then the /dev/sdb1 is
magically available for mounting.

Think it is an issue with udev.
