Edit program files

Hi. I'll try to explain this as best I can. I finally found a .deb package loader to flash my FTA receiver. However my laptop is fairly new and does not have a serial and I have to use a serial to usb adapter. In the program for the loader,,it only list serial ports,,ie ttys0, ttys1, ttys2 right up to ttyS4. I was wondering if there was a way to edit the install files in the .deb install package to have my ttyUSB0 in the list as well,,which is where it says my usb-to-serial adapter is connected. Thanks.

google..there are several other threads on forums on it.

I have the program working,,I only want to know if there is a way to add or modify the program installation files so it will show the port my usb adapter is using.

really? It's pretty hard to find...

can someone put the link for the thread that teaches this?

I would appreciate it lots
