USB CDC Communications for Dummies!

[OzGrant]

G'Day,
Used Mecanique cct(20M 18F4550) and PBP2.6 and after adding

@ __CONFIG _CONFIG1L, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L
@ __CONFIG _CONFIG1H, _FOSC_HSPLL_HS_1H
and then enabling VREGEN config bit got the Windows USB Device Not recogised message.
Are there any other config bits that have to be changed.
Is it possible to get a hex file for this project so I can at lest check my cct.
tks

G'day (again)
My problem cured when I added a 10MFD cap on the two 18F4550 power pins.
I was using the USB 5v to power the card.
So can now start playing(at last) with USB.

Windows sees a pic18 usb cdc device s inserted, but finds no drivers.

windows 7 32 bit

yes the above error was me stupidly not showing windows device mangler where the right .inf file was, my bad...

But..

I am now doing a ' USBIN endpoint, buffer, count, nodatatloop ' every second or so, problem is when I send data to it, I only get it one byte at a time, so reading 'cat' takes 3 seconds......

count variable is always 1 if data present, so i get 1 three times then it returns to zero

surely I should get all 3 bytes into my buffer and a value returned of 3 for count.

I dont lose any chars from my text string in the terminal, i think it buffers and does some form of flow control, but when i copy a text file in a dos/command window, i do lose them, i get a count of one for the first 'C' but then a zero as 'at' have got lost before i got a chance to read them.

Ok cant edit the above but it goes like this, if i send 'cat' with hyperterminal or putty i get 3 individual chars at the pic end so need to read 3 times, if i send it from a program written in vb6, i get a 'cat' in one loop/poll etc and a bytecount length of 3, as expected, hope no one else falls foul of this.

For anyone using this with WIN7 64 bit here is the *.inf driver file.
