[Flashforth-devel] PIC 18F4550 usb wiring hookup?

[craig b. <dab...@ya...>]

I'm trying to see how high I can push data-rates with PIC18-s.  The eusarts  appear quite happy to talk to each other at 921.6Kbaud but I'm hitting a wall coming back to a host PC (Terra-Term under Win-XP for port control).  The laptops with actual db-9 serial ports all seem to top out at 115.2K.  The USB-RS232 adapters I've got will go 230.4K

I'ld like to wire up the USB on a 4550 I've got on my bread-board, but haven't ever done that before and don't have a schematic for a working design as a roadmap.  Chip docs suggest that RC5/D+ and RC4/D- can be directly connected without buffering or glue(?!).  Is this true?  The USB TYPE A FEMALE Mating Face Diagram I found shows 1=+5, 2=D-, 3=D+, 4=gnd.  Are these direct-connect to the chip lines or do they need to be cross-wired like a null-modem?

Any advice appreciated at this stage.

In an almost unrelated matter, does anyone know of a way to get Yahoo-Mail to redirect replies from mail-list posts back to the mail-list rather that the individual posters?  Mike's getting annoyed with me and I don't always think to originate a new list-thread for every reply/followup...  (things were simpler back in the day when we used uucp to distribute newsgroups (grin))
