Weird. I got a thunderbolt extension cable for my dock, and it clearly "works": my laptop is charging through it, my secondary screen came on... but the USB didn't. So I have no mouse.How does VIDEO and POWER work but not something as simple as USB?

@foone It turns out that creating one cable to rule them all isn't so simple. Who could have ever predicted that?

@foone because the USB 2.0 wires are completely independent from the 3.0+ stuff. USB is a very normal standard

@foone Every year, USB controllers seem to get less and less resilient with respect to the older protocols.

it's probably just an issue with the ridiculousness of my setup.I've got a laptop hooked up to a thunderbolt extension to a thunderbolt dock, which is connected to a USB (A) extension cable to a hub to my mouse. Frankly the surprising thing isn't that this broke, it's that any of this works at all

I wonder if it works if I drop the hub. that's the easiest part to remove from the equation

@foone When I had the same problem a while back the problem was that the dock did usm-over-thunderbolt, i.e. had a usb controller in the dock connected to the host via pcie. my bios had a thunderbolt security mode configured that was blocking pcie over usbc

@adnidor hmm, interesting. I'll check my bios settings.But the weird thing is that it works without the extension cable and doesn't with

@foone Flip the cable over. The USB2 lines would need a flippy-mux in the cable* to work in both orientations. USB-C is so fucking stupid.*why isn't this the responsibility of either endpoint?

@foone @cinebox I have an extension going from my (pre-thunderbolt?) RpL laptop to Steam Deck Dock, and USB 2 only works in one orientation.Seeing as "flipping" didn't work out for you, maybe your extension cable has not two, not one, but zero orientations of USB2 lines?

@foone Hint: buy a Logitech wireless mouse. Doesn't really matter which one (I'd suggest any of the Bluetooth ones, unless your laptop has Realtek Bluetooth on their pre-AX WiFi cards), because I've seen intermittent problems with every other wireless mouse I've tried (this includes even higher-end Microsoft mice).
