July 9, 201510 yr MB: Biostar TA970 Super IO Chip: ITE IT8728F CIR Controller IO=220h; IRQ=10; It is located at /dev/ttyS0/ at least, as near as I can tell... more on this later.

RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 07) I have the below suggestion (unRAID gives me an error when added to the XML): I would guess it is serial based, so you might be able to use this for passing through <hostdev mode='capabilities' type='misc'> <source> <char>/dev/ttyS0</char> </source> </hostdev> Where /dev/ttyS0 is the device you are passing through. You will have to change it to match your device.
July 9, 201510 yr i'm going to ask the obvious question... do you have the optional cir receiver they mention here ? http://www.biostar.com.tw/app/en/support/faq_content.php?S_ID=700 it seems that it is just a header until you get another part... but it could be lost in translation as it mostly in pictograms
July 9, 201510 yr In the unraid command line, what does this command return: setserial -g /dev/ttyS[0123] Or this... dmesg | grep tty John

Please follow the instruction here for enable the CIR function. 1. You will need to Enable the CIR device in BIOS. It's under BIOS>Advanced>Super IO> CIR controller. If you don't Enable it, CIR driver will not install properly due to unable to detect the CIR device.
July 9, 201510 yr Author Did you try with the different /dev/ttySX? The XML gives an error when trying to save it. i'm going to ask the obvious question... do you have the optional cir receiver they mention here ? http://www.biostar.com.tw/app/en/support/faq_content.php?S_ID=700 it seems that it is just a header until you get another part... but it could be lost in translation as it mostly in pictograms Yes, it is installed and enabled, it has worked previously when this was a bare metal HTPC motherboard. In the unraid command line, what does this command return: setserial -g /dev/ttyS[0123] Or this... dmesg | grep tty John setserial -g /dev/ttyS[0123] /dev/ttyS0, UART: unknown, Port: 0x03f8, IRQ: 4 Which doesn't line up with what the BIOS tells me, however, if it works. It works. I'm also guessing by the "UART: unkown" that means that the driver isn't part of unRAID, so it can't be passed anyway. Is that correct?
July 15, 201510 yr Sorry for jumping in without reading all the replies, but is this supposed to show up as a PCI device?
July 15, 201510 yr Sorry for jumping in without reading all the replies, but is this supposed to show up as a PCI device? I do not think so. It is most likely connected internally on the motherboard to a com port.
July 15, 201510 yr Author It is on the same controller as the onboard serial and parallel ports, it just shows up as a serial port. In this case /dev/ttyS01/ or some such I won't be home until Friday to look.
August 31, 201510 yr Author Whoops, kind of forgot about this... it is /dev/ttyS0/ I guess the other big point is how do I go about installing the driver for this? I have a second board I can play with with say... OpenELEC or some other distro installed it for testing without having to take my unRAID box offline. Edit: I looked at the Windows INF driver and it's a ITECIR, the *nix driver for which is apparently here... however, I know dick all about building my own driver/kernel for *nix
