Probably.  Most of the USB serial cables have a limited set of control
lines that you can manage from Linux, unfortunately.

So, if your GPS requires careful, or software, control of sending
breaks, use of the RTS/CTS lines, or something like that you may hit
problems.

If all you require is an async serial port without anything fancy,
though, it should just work.

No, not if it is going to work at all.  Just plug it in, then talk to
the USB serial port like any other serial port.
