CMD Active Level:1839 mV
Box IO Level:2800 mV
CLK Rate:24000 kHz

Connect data(cmd, clk, d0) first Or connect Power(vcc. vccq) first.
Try it.

Hi CMD Pullup Level:505 mV its to low for success connect - try to connect USB power and use HiPower mode.

I got the same ISP REV 2.1 adapter...
maybe we have to add the two resistor on R2 and R3? 100Ohm, right?

Yes, you can add 100-200 Ohm resistors for better CMD/Data_0 levels recognition
