I've done more testing on my USB speed issues.
There are a subset of usb mass storage devices that write files at 300-500 kb/s, these work at full usb 3 speeds on my other PC. Some are external powered and others are passive from the socket.
Every disk that is affected is consistently slow to write files on all usb3 sockets on this motherboard including front panel, reading files from them is is fine. I have both powered and passive usb mass storage devices athat aren't affected on any port.
I have a usb3 (type c) usb soundcard (m audio 2x2m) that stutters and pops as well on both usb2 and usb3 ports, also fine on my other intel PC.
There's something demonstrably wrong with usb support at a driver level.
Motherboard is an Aorus Pro x570, CPU is a 3900x.
