Re: [avrdude-dev] avrdude: usbdev_open(): did not find any (matching) USB device "usb" error on Mac OS X

[JS]

Unplugging and re-plugging the device seemed to do the job.

avrdude -c avrisp2 -p t13 -v -P usb

avrdude: Version 5.5, compiled on Mar 18 2008 at 20:25:02
...
        Using Port            : usb
        Using Programmer      : avrisp2
avrdude: usbdev_open(): Found AVRISP mkII, serno: 0000B0018274
