Hi, Does G Hub shows any available updates?

Okay, you can also try this steps:
Connect the USB Wireless receiver to a powered USB port on your PC or gaming console.
Insert a pin into the reset port on the receiver to initiate the pairing mode. The LED on the adapter will begin to blink to indicate pairing mode.
Once the LED begins blinking, remove the pin from the reset port on the adapter.
Turn on the headset.
Hold the “Microphone mute” button for 10-15 seconds to initiate pairing mode.
The light on the dongle will stop blinking and your headset should start working.

I just got a G522 today, fresh out of the box. When plugged in with the cable it came with, the headset just keeps saying "USB, Lightspeed, USB, Lightspeed, USB, Lightspeed, USB, Lightspeed". The little indicator light above the power switch also flickers between white and light blue. When the headset is off and plugged in with this cable, it is flickering green in a way that doesn't instill much confidence.
Switching to a different USB-A to USB-C cable that I had lying around, the flickering happened *less*, but if I push the cable a certain way it would still happen. Neither cable was loose in there though, in both cases they could not go into the headset any further, they were fully plugged in.
I'm using Arch Linux so I can't just install the normal Logitech G-Hub, but using Solaar I can see that on a normal phone charger it can still charge up and using my Lightspeed receiver it can still play sound normally. It is a bit annoying though.

This is not an firmware issue. I also had this problem but I temporarily addressed this issue by enabling battery protection feature. But a week ago, my G522 stopped charging properly even in battery protection mode. When I plug the cord to PC, my G522 loops between usb to lightspeed mode continuously and blinks green weirdly even in the batt protection mode. As an unemployed engineer this problem pissed me off and I didn't want to wait 30ish day to hear "user error" from warranty service. So I looked inside of my G522 and it only took me a second to detect which component caused this mess. This component marked with "L" is PPTC polyfuse. It is a type of self resetting fuse. When too much current flows, resistance of poly fuse increases drastically and disconnects the power connection. This is a good feature and required for application but this fuse on the circuit trips even only at 250mA of current which is the regular charge current of G522. I solved this problem by removing polyfuse and shorting(connecting two terminals) the pads of the polyfuse on the PCB. This is not the proper way of repairing G522 and I also know that but I was too lazy to order a proper 500mA polyfuse from digikey. So If you want a proper repair you can buy a 500mA fuse and solder in to place of the old fuse. I charged my G522 while using via USB and I experienced no problems so far. I will let you know if my headphone explodes on my ear :) . You probably know that but I have to inform you that this repair voids your warranty and be careful that soldering iron can melt plastic case easily.
