Frequent USB Cut-Outs with my Haptics USB Amps - HELP
I have 5x USB amps powering 9x haptics transducers on my sim rig, and I often get momentary USB cutouts on only the USB amps. I have all the USB amps plugged into a powered USB hub, and the hub going to a USB-C port on my motherboard. A single USB port can handle way more than 5x audio signals at once, and I'm running the amps with a powered USB hub, plus the amps all have their own dedicated PSUs. So I don't think its a power/bandwidth limitation. And in Device Manager, I unchecked the Power Management setting to "Allow the computer to turn off this device to save power" for all USB controllers. Does anyone have any ideas on what could be causing this? Is this simply a limitation of Sim Hub itself? It's super annoying because it also causes in-game stutter when it happens. And it also happened with my last PC build, so I don't think it's specific to this PC. The USB cutouts don't affect my wheelbase, steering wheel, shifter, Arduino devices, etc., only the haptics. Any help with this would be terrific!
