Oops, just noticed the USB requirement. Yes, the Gumstix folks are
taking their time over sorting USB host. It's in the pipeline
allegedly, but I'm not holding my breath.

Different parts of the board have different IO levels; 8 pins are 3.3V; 
others are 5V.  You will need opto-isolators or similar in the real 
world (but don't you always?) You can also get daughter boards with 5V DIO.

I have one in hand and am building the power supply as we speak.  Nice 
unit, tiny, but I have a bunch of work to do before I start playing with 
it - need to build a DIN rail mount for it, etc.

www.cogcomp.com :    CSB637
www.mechatronicbrick.dk could do the job with the right motherboard.

Both have Ethernet, USB Host + Client, 2 UARTs (chips got 4)
SPI, I2C , GPIO, RTC. No ADC on the mech'brick AFAIK.

There is a growing movement to use one of the wireless routers (like a
linksys wrt5x?) which is an arm based Linux with a wireless capability
built in.  There are also hardware hacks to add serial ports on the web
... and other mods available.  This for about $40USD, with power wart,
enclosure, antenna and all that ... google is your friend ...

Cheers,
Rob.

CM-X255 or CM-X270W from Compulab, starting around $50 ? Cf

Yes, but that $50 is a bogus price, it's a few thousand dollars to get
set up and the $50 is only for a mini module that requires a baseboard
to get any actual functionality.

For full linux

Etrax from Axis  http://developer.axis.com
More recent chips can run a default 2.6  linux kernel

 The ETRAX 100LX Multi Chip Module includes the ETRAX 100LX SoC plus 4 MB
Flash, 16 MB SDRAM, Ethernet Transceiver, etc. This chip is ideal for
Ethernet-connected Linux systems.
http://developer.axis.com/doc/hardware/mcm/4+16/MCM_datasheet.htm
http://developer.axis.com/products/etrax100lx/index.html

a.. 4 asynchronous serial ports
a.. 2 synchronous serial ports
a.. 2 USB ports Host 1.1
a.. 2 Parallel ports
a.. 4 ATA (IDE) ports
a.. 2 Narrow SCSI ports (or 1 Wide)

I had a look at axis a little while back but I couldn't find any info on 
the MIPS rating. Also I found that the 10/100 Ethernet is slugged to a max 
2 (or 2.5) MB/s. Somthing to do with the USB interface.

A little correction : they are effectively starting arount $50 in volume 
orders (1K), see their prices on their web site. These kind of modules are 
COM, meaninf effectively that they are designed to be fitted, like a 
component, on your application PCB. So yes a baseboard is needed, but it 
could be either a standard one (PC104 or ATX, around $30-$40), or your own 
application PCB.
