Hacking Question USB working on Switch Linux (kind of working)

[dawid]

I managed to get the switch to recognize a USB HDD using a Samsung USB-C to USB adapter. The switch does not supply USB power, however, which I suspect is the fault of the
bq24193 power management IC and how it is used in Linux, which meant I needed to apply power to the USB hdd using an external PSU. Perillamint has made a great walkthrough (blog dot quendi dot moe/2018/07/03/en-debugging-nintendo-switch-linux-power-management-battery-desync-edition/) of comparing how the power ICs are used in Linux and horizon, fixing battery desync issues, but I am nowhere near as knowledgeable to do this (and I don't have a 1.8v USB-Serial adapter), especially patching the kernel. I hope someone else manages to get it working.

Hey there !

That's awesome ! Nobody answer to that ??
Do you think you'll get the possibility to get dock (at least video signal) working ?

good job !

Before I even go through the process of reinstalling Linux on the switch, are we sure it is capable of USB power delivery?

I've had a few unique SoCs in the past that omitted the 1st pin entirely, and some that required jumping a pin to get power delivery going.
