I searched on the internet to verify my connections, they look good: image
I think your connections are turned over on the 10 pin cable. Notice the key on the cable end. Rst is always right below the key.
Is there any possibility the cable has been put together with the leads swapped 1-10- 10-1? Just asking because I think the key is on the bottom in your picture and I am having trouble matching any cable I have to your set-up.

I do not think so.
1. Follow red wire on flat cable.
2. USBasp's G (green :) ) LED  is on, so the power is OK - VCC,GND

However, it worth for checkup.

Well, since I have the natural ability to hook things up backwards , it's entirely possible I am wrong. :)  


When I expand the end of the 10 pin cable using a JPG viewer, I still don't see the key on top. The way I see it, the 4 leads are always on the key side of the connector and the Vcc and Gnd on the other side.

I also have a batch of Usbasp's with the long 10 Pin cable with the Red tracer on pin 10 instead of pin1. I might add also , that having a 10 Pin to 6pin converter with the leads marked helps to keep things straight.

Truly, I missed this.  ;)  Hmm, I have doubts now, but how about power?
EDIT: You confused me. It should no be a problem. It does not matter how the connector is turned, red wire is always at same position.

It matters when you assume the red tracer is always pin1 and you are connecting single leads to the end of the cable.
