COM Port Issue

I have a device called a DataSafe2 which provides an interface to allow storing data from a radio control computer transmitter in a file on a PC.  The device has a serial port, and I plug it into an adapter that plugs into a UBC port.  The adapter is supposed to be on COM 4.  The system has worked in the past.

Currently, the computer cannot find the interface device.  When I look at the COM Ports in Device Manager, only COM1 and LPT1 show up as having anything on them.  

In addition to the DataSafe2 I have a WACOM (not currently plugged in) sketch pad, and a Palm cradle connected via USB.  

How do I get my computer to see the COM4 port so I can use the interface?

I can't say I know what an UBC port is, but if it isn't a proper serial port, the COM 4 is very probably a virtual COM port, in which case this is very likely a software (driver) issue. Did the adapter come with some kind of installer software?
the com port on the computer is probably disabled in the bios.  Enable it.  If it has to be on COM 4 (i am not sure why that would be) then add the port using the add remove hardware option in control panel (may need to add com3 as well)
