I'm trying to troubleshoot an issue with my Sennheiser P373D headphones, and one of the Sennheiser KBs said to ensure the headphones are plugged into a USB 2.0 port (as it can often have issues in 3.0 ports).

I have an ASUS ROG Maximus IX Hero motherboard, which should have a mix of USB 2.0 and 3.0 ports. I ensured the headphones are plugged into a 2.0 port (a black USB port, and not a blue one), and have tried a few different 2.0 ports but all show the same results in UsbTreeView.

UsbTreeView is showing the following connection information for the headphone port (and for all USB ports for that matter, including the keyboard and mouse):

C++:
        ---------------- Connection Information ---------------
Connection Index         : 0x07 (7)
Connection Status        : 0x01 (DeviceConnected)
Current Config Value     : 0x01
Device Address           : 0x03 (3)
Is Hub                   : 0x00 (no)
Number Of Open Pipes     : 0x01 (1)
Device Bus Speed         : 0x01 (Full-Speed)
Pipe0ScheduleOffset      : 0x00 (0)

        --------------- Connection Information V2 -------------
Connection Index         : 0x07 (7)
Length                   : 0x10 (16 bytes)
SupportedUsbProtocols    : 0x03
 Usb110                  : 1 (yes)
 Usb200                  : 1 (yes)
 Usb300                  : 0 (no)

I removed all my other USB devices so only my mouse, keyboard, and headphones are now plugged in. Any ideas on what i need to update to make Windows 10 detect the port as USB 2 and not USB 1?

What is making you think that the Sennheiser PC 373D operates at USB 2.0 speed? The dongle itself only supports USB 1.0 speed.

Keyboard and mouse only operate at USB 1.0 speed, also, no matter if they are plugged into a USB 2.0 or USB 3.0 port.
Hey - thanks for the tip.

I took a look and their was a newer version of the Intel Chipset driver available. So I've installed that, rebooted, and confirmed it is now showing 10.1.1.45. But, UsbTreeView is still showing the USB devices as connected on with a Device Bus Speed: 0x01 (Full-Speed).

This is odd. I'm running low on ideas of what else to check.

AHH, thank you. I was assuming that the headset was 2.0 since the FAQ said to not connect it to a 3.0 port. That was a bad assumption. I just grabbed a thumb drive and plugged it into the ports and confirmed they registered as 3.0 / 2.0 where appropriate.

THANK YOU!
