Assume you are referring to the HR24 (HD DVR), as opposed to the H24 HD receiver....

There is no firm, defined purpose (at this time), but it is a live USB port that has been used by a few folks for things like powering USB cooling fans, AM21 OTA tuner, and so forth.

For the AM21 add on OTA tuner.

You can use it to power some usb devices also, like a cooling pad, but that's it.

I use a Paterson Technology TV Translator on an H24 to control a HTPC. So yes, it "can" be used to control a PC tuner card, but whether your dongle works or not, I cannot say.

Yes on the RS232. I currently have my entire home connected via a RTI control system. The D* boxes are all connected to the system via USB to RS232 adapters. The channel changing (and anything else sent via code) is so much better than hard keys on a remote since the RS232 is a direct line of code for each command. For example, I have several pages of channel logos on my RTI remote touchscreen and the single touch of a logo tunes instantly to that channel with no channel numbers entered or shown on screen. Totally removes the time lag of entering a channel number plus enter as well as those spurious channel commands (i.e., double number when only pressed once) Absolutely love it!
Cheers,
