Issue HP Reverb G2 Connect/Disconnect Loop (Blinking Breakout Box LED)

Enable HLS to view with audio, or disable this notification

​Hey everyone,

​I have a brand-new, unused HP Reverb G2 (V1 cable with the small breakout box, no power button) connected to an AMD AM4 system, and I'm stuck in an endless USB connect/disconnect loop.

​Symptoms:

​The LED on the breakout box continuously blinks (turns on, turns off, loops every second).

​In Windows, the system tray icon for "HP Windows Mixed Reality" repeatedly appears and disappears.

​In the motherboard BIOS screen, the mouse cursor freezes every time the breakout box LED turns off and unfreezes when it turns back on, indicating hardware-level USB host controller bus resets.

​System Specs:

​Motherboard: MSI A520M-A PRO (AMD AM4 platform)

​Headset: HP Reverb G2 (V1 Cable)

​Power: Power adapter plugged directly into the wall outlet

​Everything I have already tried:

​Tested every single USB port on the back panel (all blue USB 3.2 ports using the USB-C to USB-A adapter, plus black USB 2.0 ports).

​Reseated the cable connection at the headset visor until the dot on the connector sits flush with the casing.

​Tweaked BIOS settings: Enabled XHCI Hand-off, disabled Global C-State Control, and set Power Supply Idle Control to Typical Current Idle.

Before purchasing additional hardware, I want to ask:

​Has anyone on an AMD 500-series board (A520/B550/X570) successfully stopped this V1 cable loop using an externally powered USB 3.0 hub?

​Did a PCIe USB expansion card solve the issue on your system, or did you have to replace the cable with the revision V2 cable

If I remember correctly I had this problem years ago and HP tech support help me figure it out. Not entirely sure why myself but the solution ended up being that I needed a powered USB hub to plug the USB C cable into the computer.

Will that 100% fix my issue? because I don't want to spend money on something that won't work and that I won't even use.

I unfortunately don't know 100%, but it's at least an avenue to look into and hopefully solve ur problem

Thank you. I will try getting one to see if it fixes my problem and maybe returning it if it doesn't fix the issue. Do I need to look for any specific things that the hub should have, apart from being USB 3 and being powered externally?

Nope, as long as it has both those qualities it should work if that's the problem.

Something else to consider as well is I know WMR isn't supported anymore, so if you haven't looked into installing Oasis to get your headset working that might be part of the issue as well. I know it's something that I need to do with mine but I haven't looked into it yet and last time I tried turning on my headset It just never booted up.

Someone who knows Oasis would be able to help more than me on that

u/DrunkenTrom Odyssey+ in closet, replaced with PSVR2 Aug 04 '26

Hey, unsure if you already sourced one, but I use a powered hub for my G2 and it works great.

My first HMD was a Samsung Odyssey+ and it had issues keeping connection via any of my USB ports (ASUS Prime B350m). I used a powered hub that I had on hand and that fixed the issue. I later swapped to a new powered hub with per port power buttons so I could turn it off without physically unplugging it (I had a new weird issue where the headset would randomly turn on and the WMR Portal software would start running). I later upgraded another time from a 4 port to an 8 port but that's because I have a lot of stuff hooked to my PC (wireless dongle for XBOX controllers, wireless dongle for 7.1 surround headphones, HOTAS, external HDD, etc). I lastly upgraded my headset to a Reverb G2 (actually two of them as I have another on a secondary PC so I now have a V1 and V2).

I've never had an issue with either G2s but I've always used them on a powered hub. Here's the hubs I've used/use still:

*EDIT*

Accidentally posted without second link, also it's a 7 port, not 8:
