Why won't kb3 (in Kubuntu 12.04) recognize a USB drive and allow me to burn an ISO image to it?
kb3 is the default iso burning application and it gets generally good reviews. But it pops up a dialog telling me that I don't have an optical drive and it refuses to allow me to select the USB drive. What am I overlooking? The computer is a ThinkPad X220 tablet without an optical drive.
What's another recommended way to burn an ISO to a USB drive in Kubuntu? The ISO is for a firmware update utility. (My question is not about how to install Ubuntu.)

Regarding upgrading firmware using linux:
You can refer to this page from lenovo forum. It worked for my x220. http://forums.lenovo.com/t5/Linux-Discussion-Knowledge-Base/Updating-the-BIOS-via-USB-X220-s-running-Linux/ta-p/674677
Here I paste the steps over, but credit goes to writer of geteltorito.pl
1.Get the bios update iso (8duj10uc.iso or later) from the lenovo support site.
2.Get 'geteltorito' and extract the boot image from the iso (isobar.c probably works too)
3.Copy the image to the usb thumdrive
$ sudo dd if=biosupdate.img of=/dev/usbthumdrive bs=512K
Reboot, Press F12 and boot from thumb drive.
