Usb programmer problem..

Hello You!

I've bought a new usb programmer, called GTP USB SUMMER (driver's file), and I do not know what is going on.

I am using WinPic800 and the hardware's name is GTP-Usb-Lite. It DOES NOT detect 12F629 (two brand new pieces of this pic) and a used 16F88. It SOMETIMES detects the 16F877. Could anyone help me please? I know that 12F series are problematic but it should work.

Thanks in advance for the attention..

That looks to be a good design ... LOL !!!
