He didn't say "USB hub". He said "serial/usb adapters". I've had problems with them -- the
first one I got didn't support Break (which is not a character, but rather pulling the
computer's Data In line low (or was it high) for an extended period of time (and of course
the first thing the box I bought it to use with needed was ..... a break, to wake it up.

Some of them don't support some of the other obscure corners of the serial port protocol.

There seem to be two price points..single channel, serial only for
about $190 from Milltech or dual channel USB capable from Safe Passage
for around $800. I'm thinking single channel is adequate but I my sole
serial port is occupied by the GPS and I've had problems in the past
with the serial/usb adapters. Anyone know of a single channel USB
output receiver?

You could use a MiniPlex-Lite, a small NMEA multiplexer with a USB interface
and one high speed input for your AIS receiver next to two normal NMEA
inputs (GPS, etc). And it comes without the typical problems found with
serial/usb adapters. This box simply works.

Meindert,

No flame intended, really! What are the typical problems with USB hubs?
Thanks!
