USB troubles

craig_uk · 30 Oct 2020 at 20:01

Hi, hoping someone can help me. I'm having massive stability issues when adding usb devices to my setup. Typically this causes random reboots or causes the Oculus application to restart. System specs below and also USB devices list.

Corsair 650w PSU
Ryzen 3600
Asus Rog Strix B450-f gaming motherboard
32gb DDR4 3600
GTX 2070
2x 1Tb M.2 NVME drives

USB devices.:
Logitech wireless mouse
USB keyboard
RiftS VR headset
Fanatec DD2 wheel
Heusinkveld pedals
AIOlogs shifter

I've tried putting devices in different ports but no change.

I've just ordered a PCIE USB 3 card to try and put some of the usb devices on there in hope of fixing it.

Any other ideas?

Motherboard bios up to date ? And Motherboard drivers

Yes, I updated the bios a couple of weeks ago and also installed drivers although I think that Windows 10 is still using Microsoft's usb device driver rather than the manufacturers driver.

I would use the manufacturers drivers to see if that resolves the issue.

Is there a way to force windows to use the manufacturers driver over the default windows driver?

I think by just installing the manufacturers drivers should do it, as windows usb drivers are basic.

Thanks, I'll try again. I've already done that and for whatever reason it's still using the default Microsoft drivers

It should automatically use the manufacturers drivers once installed, if not there are a few guides online.

maybe a powered usb hub would solve the issue?

Thanks, must admit that I'm suspecting that my RiftS may be the main culprit by drawing too much current. They only connect to the display port and USB port so therefore gets all of its power from the USB bus.

I've got a PCIE Inatek USB3 card on order which is powered directly of the PSU. I'm hoping that fixes the issue.

that should work as well
I understand that you tried using your pc without oculus to see if that's the problem?

Do you have a spare psu to test with?

Saw it once before where plugging in any usb device caused a crash due to a faulty psu

I've not done that, purely because the PC is for use on a driving simrig and at the moment is running totally headless (other than an HDMI monitor emulator which I've used for months). Definitely agree that doing so would help me better understand the cause of the problem.

I have to admit that I have thought about the possibility of a PSU issue. The current PSU is a 650w Corsair unit, bought in April this year.

I'm thinking of getting a new 30 series or AMD graphics card so a new PSU may well be on the cards anyway.

Just a quick update. Fitted new PCIE Inatek USB3 card yesterday and installed OEM drivers and the system whilst more stable than before is suffering from random crashes and reboots.

Although I've not mentioned it, I'm running an all core overclock on my Ryzen 3600 @ 4.2ghz and my gtx2070 is running a GPU OC of 200mhz and memory OC of 1Ghz.

I've been running those clock speeds for some time without issue but think it's important to revert back to defaults just to confirm that they aren't the culprit.

So other than potential OC side affects or possible PSU I can't really think of anything else.

It does seem rather strange that adding just one extra USB device (AIOlogs sequential shifter), tips the balance and makes the machine unstable. It's not the shifter as adding a USB flight throttle does exactly the same thing.

Wow.. So you didn't check it stock without overclock?
That's the first thing you do when you experience random crashes

Well only because the system is totally stable, then add one USB device = unstable, disconnect USB device = back to being stable again. Although unlikely it's definitely worth going back to totally stock speeds.

It sounds like your oc may be borderline. Are you running your ram at stock?

That aside, I'd still try a powered hub for the more demanding items. Do they have an option for external power?

I think regarding the overclock, if any change it may be reduced power consumption rather than outright clock speed. I'm running default RAM settings and also bus settings. Any increase in speed was gained purely from the CPU multiplier.

Had a strange outcome this morning which makes little sense. As already mentioned I've been running headless, just on my VR headset with a monitor emulator plug in the HDMI port of my graphics card. Anyway, connected a monitor to aid fault finding and after nearly 3 hours of heavy use with all usb devices connected, no issues.

Will keep on testing with the monitor connected and see what happens.

adrichardson81 · 1 Nov 2020 at 20:38

See how it goes - can't rule out the headless adapter causing the problems.

I've had problems with power-hungry usb devices in tune past, but that's always been with front panel ports
