I am trying to usb interface my PIC18f2550 with PC. I am using WFF HID USB demo from waitingforfriday.com .The problem is that the LEAPER 48 universal burner is not picking the config bits. I compiled the code with C18 compiler in MPLAB lite ide. The problem is that PC recognizes HID device but its very random. Sometimes it picks and sometimes not. I think the problem is with the internal pull up registers. They are set in the code but when I measure the D+ line it only has about 0.5 volts and VUSB has about 2.9 Volts. I think the problem is with the LEAPER 48. Because in device ID it shows all zeroes when I load the hex file. Please help.
