usbnt jtag doesnt detect when powered on or conncected

dont know for the life of it im using a ttl it powers up it says activated go in device manager it shows usbjtagNT but as soon as i put that clip on the chip to read or as soon as i hit ID, it goes to not activated and then in device manager USBJTAGNT will dissappear and goes to UNKNOWN

You have big issue. Check your connection. Somehow you have short the GND or power.

finally figured it out due to the process of elimination LONG STORY SHORT my TTL and usb cable was BAD, now everything is great USBJTAG-NT works flawlessly now
