I intend to bring out the Raspberry Pi shortly. The only downside is that
the USB functionality is hindered greatly by the fact that both USB ports
and the Ethernet port all tie into the same bus. Also, I don't mind running
headless, but with both USB ports taken up by USB-serial converters, I
won't have a spot for a flash drive. Either I'll map a network drive or
just suffer with using the SD card. Then again, if I use a real man's
terminal, I'll save a USB port! :)
You might check out the BeagleBone Black. It?s similar but the hardware is open (fully
documented in 4500 or so pages). I forgot just what the USB config looks like, but I do
remember that the stock board has a pair of USB ports plus Ethernet plus microSD, all
available at the same time. Oh yes, plus on-board flash so you don?t usually need the SD.
And several UARTs. There?s an off the shelf plugin board to provide RS232 level serial
I/O from any one of those UARTs. I did a 4 port RS232 level converter; design files
available if anyone wants them.
