Those annoying nonportable USB devices..

I own a Mac Powerbook G3 Lombard, which forsakes the decades-old asyncserial port for a couple of shiny new USB ports. Mostly I think thisis a good thing (which is why I bought a Lombard instead of aWallstreet), but there are plenty of peripherals out there that stillwant a serial port (like PalmPilots). So I bought aKeyspan USB-to-DB9-serial adaptor dongle.

Much to my annoyance, this dongle doesn't implement any sort ofstandard USB serial profile; it requires a driver to initialize it andpresumably to speak some special protocol to it. Keyspan didn'tinclude a Linux driver, the bastards, and since my Powerbook runsLinux with only brief adventures into MacOS, the dongle has been sittingin a box getting dusty.

Hey, wait! This thing is programmable!

A little while ago, however, I became curious about the contents ofthe dongle. Not for any particular reason; I simply succumbed to thehacker's desire to take things apart and see how they work. Well, whenI popped the plastic case, what to my startled eyes should appear butan Anchor Chips AN2131SC and a TI 75LV4737A! A few minutes with an ohmmeter and I'd traced out all the interesting connections (see below).

Basically, the Keyspan USB adaptor is a general-purpose reprogrammableUSB-enabled 8051-compatible microcontroller, plus a level shifter for RS232use. The other ICs on the board are a transient suppressor for theUSB port, and a 16-byte EEPROM to store Keyspan's USBvendor/product/serial numbers. The 8051 has 8K of RAM and runs at 24 MHz.

It's called 'repurposing'

Of course, if I'd actually been paying attention to the linux-usbmailing list (instead of procmailing it all into a file I never read), I'd haveknown this earlier, and also thatBrian Warner has already writtencustom firmware for the dongle to talk to the Linux kernel. But what I'm interested in is not using this as a serial adaptor, but as using it as a relatively cheap ($40) USB experimentation platform.

The design of the adaptor is very straightforward. The USB linescome in, go past a SN75240 transient suppressor, and connect to theEZ-USB chip. The RS232 lines go through the RS232 driver/receiver andconnect to UART and general-purpose IO pins on the EZ-USB chip. Theboot EEPROM is attached to SCL and SDA, as you would expect. For extrahackability, the spare I/O pins (most of port B) are brought out toextra solder pads on the board. Attaching extra circuitry to theseshould be trivial, but remember they use 3.3v logic levels.

IMHO,the fact that this dongle can probably be made into a simple andeffective USB prototyping platform is really cool, and I want to getthis information out here where it might do someone some good.

Windows™

I don't know anything about MS-Windows, but Aaron Jones sent me this informationabout loading EZ-USB firmware under Windows.

Enough talk, let's see some blinking lights!

It took me a few days to get all the build tools set up on my machine, but I finally put together a tiny demo.Download blinkeyspan-r2.tar.gz for SDCC-2.3.x, orblinkeyspan-r1.tar.gz for SDCC-2.2.x.(Thanks to Gregg Levine for sending me copies of these after I lost my own!)

To try this you'll need an EZ-USB downloader such as ezdownload(part of the ezloadutility). This works on BSD and Linux; you might have to hack onit a little since the userland USB interface is still changing. Remote pc online. If youwant to make changes, you'll also need thesdcc compiler.

All the demo does is cause some of the pins on the DB9 connector totoggle at 1.9 Hz. You can hook up an LED and a 2.2 kΩ resistor(conveniently, RS232 swings both ways, so you don't need to worryabout which way you connect the LED). It should be perfectly safe torun this demo on your dongle, but don't sue me if it breaks somethingor voids your warranty.

Other models

After loooking at my serial adapter, I became curious about the insides ofother models. It turns out that some of Keyspan's serial adapters aresubstantially different from others. Here's a list of what I've found. Let meknow if you have any other information.USA-19
This is the 'PDA adaptor' I pulled apart and described, above. It has one DB9port and is in a translucent case. It's probably the most hackablemodel (because it has a few unused pins) and also the cheapest.
USA-28This is the two-port adaptor in the opaque case. It's basically similar to what I've described, except:
  • it has what appears to be a 1.8432 MHz oscillator connected to pin 24
  • it has two SN75LBC776s instead of the SN75LV4737A
  • it doesn't have any spare I/O pins conveniently brought out to solder pads.
However, it should be just as easy to download custom firmware to thetwo-port adaptor as to the one-port version. The '776 is designed for Apple's'GeoPort' serial ports (RS-422 / RS-433) instead of RS-232, but it'sbasically similar to the '4737.
USA-19QAppears to be a 1-port version of the USA-28, except that it uses anADM213Efor the level shifter.
USA-28XThis is the two-port adaptor in the translucent case. It'ssubstantially different from the USA-28! It contains an AN2136SCinstead of a '2131, and instead of using the on-chip UART it has twoOX16C950s,one per port. It also hasonly a single oscillator (12MHz again), thetwo expected 75'776s, etc.

The 16'950 seemslike a nice chip for serial comms — 15 Mbps, IrDA, 128-byte fifo,blah, blah — but this means you can't easily use this modelas a general parallel I/O device just by bypassing the on-chip UART.

USA-19WKeyspan is also advertising a one-port serial adaptorin a black case which has different capabilities from the USA-19.Like the -28X, this also contains a separate Oxford UART chip. This givesit a higher speed (230kbps instead of 57.6kbps) but again makes it lessuseful for generic I/O. (Thanks to Stephen Malinowski for this info.)
USA-19QWKeyspan's web site mentions this as a follow-on to the -19W.According to Stuart Northfield this contains an AN2136SC, a 16C950, andan ADM213E — it's a combination of the -19Q and the -19W,reasonably enough.
USA-19HSBrian Onn reports that the -19HS contains, not an Anchor/Cypress chip, but aTI TUSB3410.This is like the AN21xx family in that it's an 8052 core with a USB interface, but it's notcompatible with the others. The USA-19HS contains:
  • TUSB3410 USB-to-Serial Port Controller
  • a single 12 MHz crystal
  • an I2C serial EEPROM from Microchip
  • a MAX3243C RS232 receiver/driver level shifter
The TUSB3410 can load its USB descriptors and device firmware from the attached EEPROM, but it can alsohave firmware downloaded from the host, like the AN21xx. However, the protocol is different so differentdownloaders (and firmware) need to be used for the USA-19HS.

The -19Q and -19QW both contain an LED connected to a spare pin on themicrocontroller. It should be easy to modify the blinkeyspan demoto blink this light instead (just change the port and bitmaskin timer0_isr()).

Here are the connections to the '2131 and the level shifter in theUSA-19Q. (Thanks to Ray Gannon for all of the information on the -19Q.)DB-9 pin / RS232 signal
