avrdude: usbdev_open(): did not find any USB device "usb"
make: *** [USBtoSPI.jtagusb] Error 1


I've been programming an AT90USBKey with avrdude for over a year.
After one of the many times my USB code crapped out on me,
I suddenly could not reconnect after a reset.
Not only that, I could no longer program the AT90USBKey with avrdude.
jungo, which used to show up on the device manager (I'm running XP),
is no longer there.

Now what do I do?

I'd intended this for the AVR forum.
Whoever can, please move it.

Another edit:
Nevermind, For some reason, rebooting did the trick.
