Previously I used AVR Studio 4 successfully but when I installed Atmel Studio 7 I can no longer connect to AVR-ISP-MK2 in AVR Studio 4.Try the driver inside the following archive (there are installation instructions inside): recommended drivers.I use Windows 10 and Atmel Studio 7 but I have some problems connecting to AVR-ISP-MK2?.The firmware of AVR-ISP-MK2 is based on the LUFA project by Dean Camera.Does the firmware of AVR-ISP-MK2 differ from the original Atmel firmware?.Disconnect the AVR-ISP-MK2 from the USB and connect it again.From "File -> load HEX file" choose this HEX ( CLICK TO DOWNLOAD) and click "RUN" in the "Operations Flow" section.Click "Select a Communication Medium" and then USB medium.Start "Atmel FLIP" and click "Select a target device" -> choose AT90USB162. Open its install folder and update the software of the unrecognized device (usually under the "Other devices" tab) with the drivers from folder named "usb" the device should now be recognized as AT90USB162 under "libusb-win32" tab.Download and install the latest version of "Atmel Flip" software (it can be downloaded from the Atmel's web-site).Connect the programmer to the USB and with a sharp object (needle or pin) press the upgrade pin - it is in a small hole at the back of the board (this will start the bootloader and will turn off the LED, it will also probably show a new unrecognized device in the device manager for which we will install drivers in step 3).To update the firmware please, follow the steps listed below Make sure that the libusb or libusb-win32 drivers (the drivers suitable for AVRDUDE operation) are uninstalled. Make sure that the suitable drivers for Atmel Studio are installed. Go to Tools -> Options -> Tools -> Tool Settings -> Check Firmware -> False.
