Running latest Oculus Home and drivers - On onboard Intel 3.0 ports I am still getting sensor disconnects intermittently and HMD unrecognised USB error at system reboot (HMD goes to USB 2.0 mode) which require replugging USB every reboot. But when I switch them both to onboard Asmedia USB 3.1, both Sensor and HMD works flawlessly with no error what so ever, even at reboot everything is detected properly with no USB errors.
There is something going on with Intel USB 3.0 for sure... maybe something to do with Smart Auto feature on all Intel USB 3.0 ?? even my USB 3.0 hub has problem with Intel USB 3.0 ..so might be worth a look.
I never had this issues until a couple of weeks ago. Now I can't use my rift for 10 minutes without it disconnecting.
