Darn, can't remember where I read about buffer length. I would go with 8 bytes too.

It's not going to affect performance much anyways.

I think it is in USB Complete, but have to search and the book is far away right now...

You can have the buffer any length as long as the discriptor is set correctly.

example

Code:

USBBufferSizeMax   con 16  ' maximum buffer size
USBBufferSizeTX    con 16  ' input 
USBBufferSizeRX    con 16  ' output

Code:

  ; report count (number of fields)
    retlw	0x95
    retlw	0x10   ; 16 byte buffer

it could be 3 bytes, 5 bytes as many as you want up to 64 bytes
