(true)MIDI USB Board

If this is not a brand new PIC18F2550 than LVP (Low Voltage Programming) might have been disabled with previous firmwares.

what do i do?

[dmitri]

If this is the case, than you either need to get a brand new PIC18F2550 or program yours using a high voltage programmer, e.g. a JDM programmer.

worked, i just did a lpt1 programmer and it seems that worked
thank you dmitri

I can send you a programmed PIC.

I do not have the conditions to purchase from you. I am in Viet Nam. that basis to fund any other pic is not. this case the circuit must deliver star? I bought GTP USB expertise,
in the project, especially the stock fund program for pic and AVR

Maybe I'll buy USB GTP in Vietnam.

USB problems I have, at no time received, it does not recognize when I hit the board on hand to receive it. I do not know that by being more or not? Help me with.

No offence, but can you find find someone with better English knowledge to describe the problem?
