USB-UIRT with LIRC(version 0.7.0) on Fedora Core 3 LINUX

Hi all ,
I'm new to this forum and also very new to using the USB-UIRT.
I have managed to get it working under linux with LIRC and I am now attempting to teach the device to emulate the remote control for a cable tv set top box (specifically the General Instrument CFT-2200).
I can successfully map some keys on the remote but I also have the following difficulties:
1) At times when pressing some keys after the learning stage (for testing response) , the system reports the correct key pressed but also reports another programmed key , and if this button is held down , the repeat output displays the the other incorrect key.
2) Some keys fail to get a successfull response at all from the system (during testing) after a successfull learning session.
3) How do I determine under linux whether or not I have the USB-UIRT with the 56 Khz IR detector ? I am able to be some distance from the device (10-12 feet) and have responses (the red light flashes) when using a remote.
Any help or advice would be greatly appreciated.
Best Regards,
Caspanis
