USBDemo, something to learn USB a little bit

[Demon]

Charlie,

I had a similar problem once; so I copied the Includes in the code and removed all the variables I didn't need. That worked in my particular situation.

I'm just getting my feet wet with USB. I currently have PBP (2.60C). I'd like to get some recommendations, before I get too far into this project:

1) Is there any benefit to upgrading to PBP 3.0, specifically for my USB experiments?
2) I have very little experience with VB6, but some experience with VBA (in Excel). Back on post 248, Steve said, "...VB6 being a dead duck for ages now...". I _have_ VB6, but was wondering if there was a more current alternative (other than going out and trying to learn a completely new language, like C)

Any tips would be greately appreciated!

hi,

i use USBDemo.HEX file. i send it to my PIC using USB PIC programmer (not boot loader). i use;

18f4550
4 MHZ crystal (with 22pF capacitors)
3 parallel 100nF (not polarized) capacitors on pin18
10k resistor on mclr
100nF capacitor between VCC and GND

my pc doesn't recognise the device. nothing happens when i connect PIC to my pc

what is wrong. i couldn't work it. i am workin on it for months and i am going crazy.

thanks

...well looking back it appears you can use a 4mhz. I used a 20mhz crystal when I was able to get it working.

Do you have a schematic.

this is my scheme. i tried it using 20MHZ and 15pF caps. what is wrong with it?
