Unexpected USB disconnects on my workstation after upgrading to Windows 11

I recently upgraded my main workstation from Windows 10 to Windows 11, hoping to get better performance and some new features. The machine is a custom build with a mix of older and newer USB devices: an external SSD, a mechanical keyboard, and a USB headset. Since the upgrade, I've been experiencing random USB disconnects that cause the external SSD to unmount unexpectedly during file transfers. I've updated all drivers I could find, including chipset and USB controller drivers, but the issue persists. I also tried changing USB ports and disabling selective suspend in power settings, but no luck so far.

Does anyone know if Windows 11 has known quirks with USB stability on mixed hardware setups? Are there any logs or diagnostics I can check to pinpoint what's causing these disconnects? Also, would rolling back to Windows 10 be my best bet if this can’t be resolved, or is there a fix I haven’t tried yet?
