The actual speed of the connected device should be 480 MB/sec.Įlgato has suggested a workaround for this issue, which is to use a powered USB 2.0 hub.

It will list its speed as "Up to 12 Mb/sec". According to Elgato, the issue is related to USB 2.0 devices connecting at very low speeds.įor example, Elgato Game Capture HD might show up in the System Information application under "USB 3.0 High-Speed Bus", but won't be properly connected. Anyone know a fix for this or a way to reset the USB connection?ĭevice maker Elgato also has a support page for USB 2.0 device issues when connected to Mac USB 3.0 ports. Eventually I run out of USB-C ports and need to restart the computer to fix the issue. When I disconnect my USB devices they are not recognized when I reconnect them to the same USB-C port. The problem is widespread and has been reported many times on Apple forums by different users. after a while (minute or hours) the USB 2.0 devices will stop responding (keyboard dead, mouse not moving or clicking). When I use an external USB-C hub in any port of my MBP, and connect USB 2.0 devices that include a Filco keyboard and a Razer DeathAdder mouse.
