I've long used my ISP MK-II (USB) with Atmel Studio 6, and software prior to that.
After installing a new JTAGICE3, the MK-II won't work with Studio 6.2.
I disconnect the JTAGICE3. Plug in MK-II. USB driver found, no error.
Studio lists the MK-II normally. I choose it.
But when I tell the Device Programming software to apply/use the MK-II, it says "Unable to connect..."
What I've tried:
unplug MK-II. Studio displays (disconnected)
uninstall the MK-II USB from Windows device manager, then replug-in the MK-II. Driver found, but same problem as above.
Ironic: I'm trying to use the MK-II because the newly purchased JTAGICE3 is intermittently flaky.
