I'm trying to use my Oculus Quest 2 using a link cable on a USB-C port. I've tried using the ports in the back of the board as well as a port I've connected to one of the front-panel USB-C connectors. I can only get it to work on one of the USB-A ports. If I use the other ports (USB-C), I get pitifully low bandwidth (387Mbps) vs. the 2.6Gbps I get when using the USB-A port. This is the bandwidth reported by the Oculus Software's internal testing tool. Yes - I've confirmed that the only difference between one test and the other is which USB port the headset is connected to, and the results are consistent: USB-C SUCKS!!
This makes no sense to me as the USB-C ports should grossly outperform the USB-A ports ... any ideas as to what setting(s) I might have missed in the BIOS? Any special software that needs installing? The only "unknown device" in Device Manager is a networked HP Printer that no longer has drivers compatible with this version of Windows (10, fully updated to this moment).
Please help - I can make do with the USB-A but I refuse to believe I paid top dollar for this kind of a lemon ...
