JTAGICE3 not detected!?


I'm trying to use my JTAGICE3 programmer but it's not detected by the Arduino IDE (or AS7 either on different computer). When I try use it this shows up:

avrdude: usbdev_open(): error claiming interface 0: Permission denied
avrdude: usbdev_open(): no usable interface found
avrdude: jtag3_open_common(): Did not find any device matching VID 0x03eb and PID list: 0x2110, 0x2140

I've been able to upgrade the firmware on the unit, so it's communicating. Both my Windows and Mac computer detects the unit as a USB device with the correct VID/PID and serial number. I used it three months ago and there was no problem. Anyone have any ideas?

I also have the same issue using the latest Mac OS Mojave (10.14.3).
Do you have an update on this?
Thanks !

Same problem with Mojave and JtagICE3. No entry in /dev.

Is there a solution?
