Could it be this model?

If not,
I do not think windows will recognize MIDI devices connected to a MIDI port unless you are using specialized software like Sounddiver, and have both the MIDI in and OUT connected to the device. This allows the computer to send MIDI SYSEX requests to the instrument for identification and memory dumping. Even then, I doubt that this type of software can or will recognize most MIDI controllers since they are designed to manage instruments with sounds in them.
Drivers are not used for MIDI instruments (as far as I know), since it is a standard communication protocol designed to avoid the need for such things. I have never heard of drivers for a MIDI only controller or instrument, and have never needed them for any of my instruments. Newer instruments with MIDI and USB will have USB drivers.
The short answer is, don't expect the Crumar device to show up in Windows device manager even when it is setup and working properly because there is no way for Windows to know it is there.
Windows should only be aware of:
1) Internal hardware MIDI devices (wavetable, FM, and other similar devices designed to accept standard MIDI data as if they were an external instrument, but do not connect to a real MIDI interface)
2) MIDI ports - this would include gameport to MIDI cables, or USB MIDI interfaces
If you are using a gameport or USB midi interface, drivers will be needed to enable those ports. Drivers for the USB interface should have been installed or requested automatically. Gameport MIDI support seems to have been in the process of being dropped from Windows XP, so there may be complications in getting one to work. This is because the MIDI cable connects to the joystick interface, for which some types of support were also dropped. Here are some examples of people discussing the process of getting Gameport MIDI working in XP:

I think that some standard drivers may have to be installed manually by Adding Hardware, and conflicts need to be resolved if they are present. A quick look at my current XP system shows a gameport conflict (yellow exclamation point) which appears to be common, and I have no MIDI ports on this system. The only system I have that is connected with a gameport MIDI interface is running Windows 98, as many newer systems don't even have a gameport at all.
There should be a setting somewhere in the control panel under Sounds and Audio Devices, where you can make changes for MIDI input and output devices. It will be necessary to set the computer to accept input from the correct MIDI input device once it is correctly installed. If the input setting is not there, you may have to look around the control panel or search the net until you find where they have put it.
Once installed and configured, if you are still not hearing anything, it may be the MIDI channel. Your MIDI adapter should be able to accept and monitor MIDI input on all 16 channels. You may wish to look for a utility to display incoming MIDI information for your testing purposes, unless your soft synth will do so.
Here's one called MIDI input viewer:

it requires this to run:

There are probably more recent programs of this type.
One way around this issue is to try setting your soft synth to OMNI ON which is so that it will accept on any or all MIDI channels, or even just try all 16 channels one at a time.
The device you have is probably sending on MIDI channel 01 already, although it is possible that a previous owner changed it.
In summary, I would think the problem is either:
1) MIDI interface drivers are not actually installed
2) MIDI interface has a hardware conflict in the Device Manager
3) MIDI interface is not chosen as the MIDI input device in the appropriate control panel
4) MIDI channel mismatch
One last thing, remember also to connect the MIDI OUT from your controller to the MIDI IN on the computer (some people make the mistake of connecting OUTs to OUTs and INs to INs).
If all else fails, you can probably find someone willing to trade you a USB MIDI controller or keyboard for your much more rare device.
Good luck and happy music making.
Cheers
