When I plug this Anker USB-C hub into my Steam Deck OLED USB-C port, the Steam Deck shuts off.

This happens even when nothing is plugged into the hub, in both gaming and desktop mode. Other USB-C devices (the official charger, dock, other usb-c cables) work fine. I have to unplug the hub before the Steam Deck will turn back on.

I have tried plugging this same usb-c hub into another Steam Deck (256 lcd) and there are no issues. Both Decks are using the latest stable updated OS. 3.5.7 build 20231122.1.

I’d like to use this hub for accessories, but right now I cannot. I’ve contacted Valve support already. Anyone else run into this weird issue before?

    I’ve had this exact same issue! The Anker 6-in-1 causes the power to cut out immediately on the OLED deck. Interestingly, this happens only if there’s no power provided to the USB-C PD passthrough port on the hub - If there’s power going through it, it’s fine.

    If the hub is connected while you try to power the thing on, it usually crashes partway through the BIOS boot, and if you keep trying, you get the red flash on the power LED that indicates the battery is empty, even when it isn’t.

    My assumption is that the OLED deck thinks the Hub has power to provide over PD, and switches the power draw from the battery to USB input. Then, since the hub doesn’t actually have any power, the deck immediately powers off with a hard crash.

    I’ve tried going back and forth with Steam support on this, their suggestion was to reimage the deck, which didn’t help. I’m hoping this is a BIOS issue and not a problem with the new charging electronics on the OLED deck, since the former can be patched while the latter probably can’t.
