I'm currently in the process of designing an #ExpansionCard for my new #FrameworkLaptop.

I need the #Unifying #dongle (lower latency), but don't want it sticking out and losing a whole slot.

So I'm going to throw a USB hub and the peeled dongle on a PCB and hope it all works out :D

As a further experiment, I routed the USB A SS lines past the hub (USB 2 D+/D- connected to port 1 of the hub).
Not sure if this will play nice with USB drivers, but it's worth a try.

@LeoDJ drivers shouldn't care, as USB 2 and 3 are completely separate busses :3

also, might be handy here somewhere, do you know you are allowed to switch polarity of the SS pairs to simplify routing? E.g. SSTX+ to SSTX- and vice-versa :)

@littlefox @LeoDJ yea the usb 2 lanes in a usb 3 receptacle/plug are for fallback/backwards-compat only, theoretically you could leave them disconnected entirely but then you wouldn't be able to connect usb 2 devices and if the usb 3 link fails then it won't have anything to fall back to

@chfour @LeoDJ irregular reminder that you can connect USB 3+ devices to two different computers at once with this :>

@littlefox @chfour @LeoDJ connecting a USB 2 and a USB 3 device to the same port is something I've heard of before, but this way round, that's cursed :D
