Thermaltake Toughpower DPS G 1200W Platinum Modular PSU - Issue with App not loading/USB not being recognised.

Hi, I have been fighting the DPS G PSU software and Chasing USB not recognised issues for some months now.




When I first built my brand new PC - Everything but this PSU was recognised, I switched the USB header it was plugged into and reinstalled the software a few times and it eventually started working. Then a few weeks later I got the same issue USB not recognised and the software would not load. Nothing I did would fix it.

I eventually reinstalled windows and got it working again, but now a month after that, boom, randomly USB stops working and software does not load again. I have tested both USB headers with other inputs, and they both work fine. I'm using the latest drivers/firmware/software/windows updates available for everything on/in my pc/windows install. I don't want to keep having to reinstall windows every few months just to try and get this thing working over and over again, it's becoming quite the headache, please help!

Typical, the second I post this, I figure out what the issue is haha! (At least it seems to of been the issue).

I'll describe what I did to fix it here, in case anyone else is having a similar issue. TLDR: Asus bios setting "Legacy USB Support = Enabled" fixed it for me.

In the Asus Bios > advanced menu > under the USB section, there is an option for turning on/off the legacy USB support (for non EFI devices - I believe such as the TT PSU I have). Now usually by default this is set to "Auto", and what this setting does is disable legacy USB support if it can't detect any legacy USB devices connected. This causes some issues and seems to make it temperamental as to if the PSU gets detected or not (I think it detects it until something stops it, then it can no longer detect it at all). If it's set to disabled it will 100% not get detected, but if turned to ENABLED, then it seems to be recognised and work as intended. (assuming it's just not a coincidence that I changed this just now and it worked, I will report back if it stops working again at some point - but as of now it fixed the issue).
