if you build gtp usb plus and programmed it with the firmware that you can get on the net or emule, then it is gtp usb lite firmware, and wont work with gtp usb plus hardware !

I just received a gtp usb + and i made a zif socket pcb for it, but ironically only 18pin pics' are working. For 40 pin pics it says "Write error". i double checked my circuit nothing seems to be wrong. any one know what might be the mistake ?

gtp usb+ is not free. The others are.
Suggestion: forget about the gtp and build a PicKit2.
Blueroomelectronics has an excellent kit (Junebug). It is, however, limited to 5v devices.
funnynypd also has an excellent kit. It programs both 3v and 5v devices, but uses smt/smd components (not as easy to build). Last I heard, he was (...)

I helped someone for this type of programmer before, search on edaboard and see if you can still find it.
By the way, for all the resource you can build a gtp type of programmer, you can almost do the same thing with PICKit 2. Why not give it a try when you get some time.

with the pickit2 you can program AND debug (trace) your programs. the gtp is only for programming.
also the gtp usb lite works only with winpic v3.55 - so there are quite no updates for new pics since a long time.
so for me pickit2 wins.

you must use a gtp usb LITE and the gtp software v3.55
if any of the two is not right, nothing can work.

you can also make yourself a icd2 clone (the one with full usb support - pic18f4550 and 16f877)
it is some more expensive, but it will program all the pics, and you can debug your program too...
this usb jdm programmer will not program modern pics, and as it is still rs232 it will be very slow to program big pics with 16k or more flash in it...

Verify your cable usb (gtp usb needs cable usb 2.0 with maximum of length 1.8M).
Do you have gtp-usb PLUS?
If your gtp usb goes LITE then you need the usb host.

As you say, If you have "bought" the usb programmer, ask the vendor about which is the programming software to be used with the same. If it is a Pickit2 clone, the Pickit2 programming software may be used. gtp usb, Brenner and other versions of usb based programmer and softwares are other possiblities.
