The following thread is quite good. The author is quite good at USB and he thinks that usbser.sys is weird. http://www.cygnal.org/ubb/Forum9/HTML/000945.html Still I will think "unable to open COM Port" error may not be due to the device at all. The reason may well be that there is another program is using the com port. By the way, try to use other terminal program. Hyperterminal is know to be problematic with USB serial. Realterm is a better one.
