Sped up COM port searching.  Added a few types of COM devices.

Hey Alexey, I have a couple changes you might be interested in.
I changed the regular expressions for the COM port searching to add more COM port names.  I also made is so that the regular expression is only compiled once and then checked against each filename, instead of recompiling the regular expression for each filename - this should speed up the COM port searching.
Thanks for the great work!
