After failing to check whether my USB stick firmware can be rewritten AT ALL, I want find out, whether it WAS rewritten when I sticked it in another computer. In particular the question is: how to find out, whether my USB flash drive tries to behave like different devices (or device classes)?
Would it be enough to
udevadm monitor and to see if it "removes" itself? Are there any way to controll how Linux communicates with the USB device (like in a console)?
