Is it possible to get the serial IRBlaster to work through a usb to serial adapter. The setup script gives a choice between COM1 and COM2 (thought this was linux) but obviously i am not using /dev/ttys0 or /dev/ttys1. My adapter configures itself to /dev/ttyUSB0. Is there any way i can "assign" this to "COM1"?

I am using a shuttle with no legacy ports and a tuner card plugged into the sole PCI slot
