Using a dual cpu Epyc system as a desktop - usb woes

I have a buddy I work with who is using his dual epyc system as a workstation. He’s run into endless problems with usb however, and I’m wondering if anyone has any insight as to the cause. Namely, usb at large on the system is unreliable, finiky, and 40% of the time un-useable for things like webcams.

He’s tried adding usb add in pcie cards with supplimental power leads and stuff, and external powered hubs to no avail.

Build out is as follows:
Dual Epyc 7282 cpus
128GB ECC ram (8 sticks of [Supermicro (M393A2K40CB2-CTD])
Supermicro H11DSi-Nt motherboard
Samsung 960 pro

Anyone experience something similar? I run the same system but its in my rack and I only use usb for keyboards and mice now and then.

What operating system is he using? Maybe it could be a driver related issue.

@NZSNIPER Indeed. Epyc CPUs lack official Windows 10 qualification, thus, they haven’t been tested. Linux should work fine though.
There is an LTT video about building a Hackintosh using Epyc.

Windows 10 for workstations

No WIndows 10 for Workstation certification.

Manually pulling up-to-date drivers from Microsoft’s online catalog would be a place to start. And also, updating the BIOS.

Alas, we have actually done that, to no avail (the Microsoft catalog step).

Appreciate the help though!

What about DriverMax and https://drp.su?

Here are 2019 SP3 chipset drivers from Gigabyte:

The ones provided by Supermicro for the mobo are from 2018.
Edit: The same from Tyan: ftp://ftp.tyan.com/drivers/Website%20Drivers/AMD/EPYC/AMD_EPYC_SP3_IO_V1.07.12.1102_2K12-R2_64_2K16_64_2K19_64.zip
Asus: https://dlcdnets.asus.com/pub/ASUS/server/ESC4000A-E10/SCD/AMD_Chipset_Drivers_V1.07.12.1102.zip

I’d recommend unzipping the ASUS ones and using the Device Manager’s search functionality to find locally stored drivers for every system device, or unknowns.

Alright we’ll give it a shot, much obliged

what’s the PSU, maybe flaky 5v rail?
