USB2.0 loop back plugs are now available. These plugs can be used in conjunction with BurnInTest Professional V4.0 or with stand alone test software.

More details can be found here

We are going to continue to support and sell our cheaper USB1 plugs but we expect a lot of people to prefer the USB2 plugs which are faster, have more test functions and have a cool, white colored, printed circuit board.
