Applies to: Twitch

When connected to the same bus, various combinations of USB devices experience intermittent difficulties or simply do not work. If using Twitch and another high-bandwidth USB device, positive results will be found from unplugging the other device or plugging it into another USB bus.

Multiple USB devices will not be able to compete for the relevant amount of bandwidth they need and therefore need to be used on separate USB buses.

To resolve any problems with Twitch, please ensure each high-bandwidth device has its own USB bus.
If your computer has a single USB bus, adding a USB interface card provides a second USB bus. Without a second USB bus, you may have to completely disconnect one high-bandwidth USB device to use another.
