MFD stops working with USB Audio

Hi, strange issue but I just can't work it out. Any suggestions welcome.

I have DCS + TM Hotas WH + Trackir + 2 Thrustmaster MFDs.

All work fine, if I use external speakers. At night however (to keep quiet) I need to use my USB Headphones (Turtle Beach Stealth 700). USB headphones work fine (they are through a USB switch-box, so I can also use them with my PS4). It all works perfectly well.

However, as soon as I switch on my Turtle Beach USB Headphones the 2 MFDs stop working. Pressing any button on the MFDs doesn't work in the sim. All the lights are on. If I disable the USB Headset the MFDs work fine again.

I have disabled Power Management for all USB devices/ports.

Just can't work it out. Please post any thoughts. More than welcome.

Many Thanks

Hi

My thought is that your asking your USB hub for too much power. The MFDs are hungry hectors. Certainly the hub on my secondary Dell monitor couldnt handle them both although its perfectly content to power the Track IR camera, Delan led clip and headphones.

Getting a power plug on the hub is a good idea, another oddity with DCS, and USB devices.

the headset waking up could cause the hub renumerate devices slightly differently and suddenly they identify the mfd's as different devices and won't use your defined keybinds.

Try unplugging your usb hub they are connected to, restart computer plug back in and see that helps. I have a seven port hub that sometime's all or one port will stop working and the doing this works for me. Also try unchecking hardware acceleration in your headphone properties if it is checked.

Hi all, many thanks for your replies. The MFDs are connected to an internal USB card, only the headset is connected to the powered USB HUB.

But i'll try connecting the USB headset to an internal USB slot also and see how that goes.

Please keep any suggestions coming :)

OK, fixed it thanks to your help & recommendations. It was USB power I think.

Both the USB Hub/Switch and the 2 MFDs were all connected into the same internal PCIe USB Card. I have now plugged the USB Hub into an onboard USB slot and its all fine. PCIe card mustn't have had enough power.

Thanks again all.:)
