MyGica X692 Quad Capture Card Error

[LTKodiUser]

I installed a brand new MyGica X692 quad card into my fedora machine and get the following from dmesg.

There's three pieces of hardware here.  The AF9035 USB Bridge chip, the ITE 9303 chip and the Silicon Labs SI2168 chip. 
According to all the documentation I have read, all three chips are well supported by linux.  Card works fine in Windows. 

The af9035 and ite9303 firmware seem to load fine, but the Silicon Labs si2168 never loads, even when trying different firmware files (at least 4).  I've tried each one individually, removing the rest in case of a conflict.  I've Googled till blue in the face but cannot find even a remote explanation of what error -5 is.  No one seems to know. I've tried every version firmware I could find, Including the ones from Libreelec.  I've tried every flavor of Linux, from Arch to Centos to Debian to Fedora to Ubunto, and even Kali ffs, always the same error.  After banging my head against this for a week straight, I thought I'd try posting.

Any suggestions would be greatly appreciated.

Suggestion? Don't buy MyGiga devices and expect them to work on all version of Linux. They might include binary blobs compiled for specific Linux media trees. I recently went trough this on the LE forum with another device and LE team gave the same suggestion.

Contact Mygiga support and they probably will tell you what specific kernel you need. For one device I own they wrote back "Our linux driver currently only supports ubuntu 20.04 ker5.8.0"
