Meindert,

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

I suspect you mean serial/usb converters?

Many of them don't have an internal serial number so the created com port
changes when you plug it into a different USB port. All of them support the
M$ Plug & Play support for serial ports which means Windows thinks your GPS
is a mouse. Many of them don't work as supplied, wrong drivers and that sort
of stuff.

If you really meant USB hubs, then I don't know of any problems with them
apart from being able to be powered from 12V or 24V.

Sorry, I read it wrong. No, I did mean hubs. I'm well aware of the
problems with some USB - serial converters. I seem to have a problem
with my workstation. It has 2 separate USB outputs, plus a 4 port USB
card. Each of the two ports is plugged into 4 port hubs. The only
problem I have is that some devices are not recognized. (I use two
printers, flat plate and negative scanners, plus connections for the
Garmin 530, Motorola cellular phone, Western Digital "My Book", several
cameras, etc.)
