Hello

nrComm Lib works fine with USB2RS232 adapters usually.

Do you see any errors or exceptions?
Please check that you use correct serial port settings (baud rate, parity etc.)
Did you install latest drivers for USB adapter?
Please check FT4 functionality from other terminal program (like HyperTerminal or Putty).

Also you can upload here simple project that shows problem.
