1. Please confirm your chip is a good chip.

2. Do not push the chip too deep into the socket. This will minimize the contact issue.

3. The two jumpers on adapter should set on TrueUSB and VppON position.

The default jumpers are on position TrueUSB and VppON.
The only way to know the good chip is to test on working machine or another programmer.
