So, Logitech G Hub see's this as a G533 Headset and that its inactive, basically greyed out with a little question mark saying please wake up device, but thats OK!!! well, be nice if you can go in and adjust settings on it, but beggers cant be choosers. Problem was I have a Pro X Wireless headset that had a corrupt USB DAC that Logitech had to replace... Well, they dont sell just that USB DAC and logitech i guess figures its cool with them to bite the cost and send a brand new set of headphones for a replacement after about 2 weeks back in forth with support, but now I had a brand new second set of headphones that were new but no USB DAC for it. I didnt have high hopes that this would work, but sure enough, I plugged in the device, used a safety pin to hit the pair button and the green light flashes, then on the headphones there is another pair button, careful though, its another safety pin hole, not the grey button inside which looks like a pairing button but I have no idea what it does, but the sync pin is another tiny pin hole near the bottom, deep hole but the button is there, paired up instantly and now I can use both headphones.... minus the config portion which sucks but thats ok... on headset volume control works... mic seems to work fine... I'm a happy camper!!!
