Pickit2 problem "USB does not recognize"

[Shaheers]

I have recently made a Pickit2 clone programmer on bread borad from the following link
Microchip PICKIT 2 Clone - Schematic+PCB (PROTEUS) - Sonsivri


I program the uC from Pickit2 from some institute, when i attectched the programmer to USB some time it says "USB does not recognize" and sometime it does not even respond anything

i am using win7 pro, and latest motherboard with i3 processor, can any one help me on this?

Check PCB, parts, and reprogram again firmware chip.

you claim using win7, whether 32 or 64 bit?
the link takes me to another link where i get irrelevant stuff, instead of pickit2 related.

I checked the all parts twice, the reprogramming of new latest frimware is pending. . .

On WinXP Win7 32-bit 64-bit working fine. Try to reinstall PICKIT2 software.

Check and compare firmware hex in attachment with yours.

Did you make some replacements of mosfets from circuit?

I made this PICKIT2 and all working great:

yep i am using BJTs instead of mosfets, but i think is not a problem, the main problem is USB communication, it may be frimware, may be xtal connnaction or vusb connection, as i think, , ,

 

[tpetar]

You should try to reinstall software, and try to use other usb port.

I see that inappropriate replacement cause strange situations.

that causes a problem Shaheers.
dont change the components of a working design and expect it work.
