Rendering = USB Fail?

Posts: 509
Recently, sometimes when I'm rendering, my USB Controllers on my PC will stop working. This only happens when a render is cooking, but not -every- time a render is cooking.
I have uninstalled and reinstalled drivers for the controller, and updated my video drivers.
When it happens, I have to hard restart via power button, as I have no way to control the computer (both mouse and keyboard are USB).
Anyone have any ideas about what's going on or how to fix it, before I put in a help ticket?

Last time I had issue like that, my PSU was dieing.
You should make sure your power plan doesn't allow Windows to shut down the USB controllers.
In settings choose System -> Power & Sleep -> Additional Power Settings -> Change Plan Settings -> Change Advanced Power Settings -> USB Settings -> USB Selective Suspend setting -> disabled
No, that is true. It's happened to me too. I think, but ain't sure, it's because the USB ports' bus is more dependant on the CPU having enough cycles free to attend USB interrupts than winds up sometimes being the case when someone has a heavy CPU render running. I think computer sleep states might also be playing a role.
To recover in my case, I had to turn off power & turn on power but I lost the render & had to start it over again. I didn't have to reinstall any drivers or anything though.
Also, I should add that I in January 2020, I build an AMD computer with a Gigabye B450 WiFi AM4 soket motherboard that has had already in not much over a year since it's release 7+ BIOS updates, with most of those updates claiming to address USB issues on the MB.
I will suggest the PSU (power supply) ... but instead of dying, it may be slowly overheating (why it only sometimes happens). When it overheats, the better models will start shutting down systems on the computer - such as USB ports. If it is overheating, my first suggestion is to look at the fan and any filter over the fan of the power supply and see if dust has accumulated to the point of clogging the air flow ... umm, check the other fans also for the air flow fo the whole machine. This problem happened to me and it was just thick dust needing cleaned off. Check for all fans, the power supply fan may be on the bottom of the machine.
Have you tried waiting for several minutes? I've had DAZ lock up my PC like that a bunch of times with the mouse and keyboard becoming completely unresponsive. I used to just restart the PC when it happened since I thought it was hopelessly frozen, but one time I decided to just wait and it turned out that it does unfreeze eventually after a few minutes and then starts the render as usual.
It's not freezing. The USBs stop working entirely. My keyboard and mouse have lights. When this happens, no lights, no response.
USB suspend was active. Have disabled it and will see if that helps, as well as give my fans all a good blow. Thanks, all!
That sounds exactly like what I'd expect from the USB controller being "suspended" for power saving reasons. I have no idea why you'd ever want that on a desktop but it is enabled by default in every power plan MS has ever released.
Because detecting a mouse, keyboard, or other components in USB suspend state is what signals the power plan managed by the OS that the rest of the computer components should be changed to wake state as well.
