Re: [Usbpicprog-technical] programmer not detected

Hi,

The steps you followed are right, although I can't see if you followed 
all the steps carefully.
When you plug in the usbpicprog programmer, you also have to install the 
driver (found in the program files\usbpicprog\driver directory)
If Windows is giving you this message ("Usb device not recognized"), 
then you have probably not soldered something correctly.
It could be the capacitor on the Vusb pin of the PIC18F2550.
Have you also verified that the bootloader was programmed correctly?
Have you placed the jumper between MCLR and VDD on the "self programming 
header"?
You could also try a different operating system (e.g. Ubuntu) and see if 
it works there, in Ubuntu you don't have to install any drivers.
If it's still not working, please let me know which leds on the 
programmer are on.

Kind regards,

Frans Schreuder
