Ok, I stopped by CompUSA and picked up one of the USB200M adapters,
with the ASIX chip. We'll see how long it takes me to get it working.
They also had the Netgear FA101 and the LinkSys USB100M, but I
couldn't remember for sure which chip was in which. Once catastrophe
at a time, I always say.

Also, while I was there, I discovered this thing called an iConcepts
PDA USB Adapter, which is in fact a Prolific Technology PL2303
USB to RS232 serial adapter. I've been looking for one of these
for ages, because my stupid Sony Picturebook doesn't have any RS232
ports. (It's "legacy-free.") Unfortunately, it also has a Conexant
softmodem, which is the only piece of hardware in it that isn't
supported in FreeBSD.

In case anyone cares, this USB to RS232 adapter seems to "just work"
with FreeBSD 5.0-RELEASE. I'm using it right now to connect my Picturebook
to my US Robotics 56K external modem with ppp:

ucom0: Prolific Technology PL2303 Serial adapter (ATEN/IOGEAR UC232A), rev 1.10/2.02, addr 3

This device was hanging right next to another similar device which
was a) much bigger, b) $20 more expensive, and c) claimed to be Linux
compatible. I'm glad I was a skinflint and got this one instead. :)

At last, I can use a real modem with my laptop _and_ use the laptop
as a debugging console for the Wind River development boards at work.
