USB OTG

USB OTG should work out of the box. To use keyboards and mice, do sudo apk add xf86-input-keyboard xf86-input-mouse

Notes/To Do

Required workaround: Add xz to makedepend to avoid lzma errors.

Only lt01wifi/T310 has been tested so far. I might make builds for T311 and T315 once I get T310 working.

XFCE ONLY:The device indicates when it's charging, but the actual batery percentage readings don't work.

USB OTG doesn't work (at least with my keyboard). Turned on OTG via kernel config and it still doesn't work (at least with the two keyboards I have). USB OTG keyboards and mice work. I installed xf86-input-keyboard, xf86-input-mouse, xf86-input-evdev, and xf86-input-libinput and added a config file to xorg.conf.d that had all the keyboard settings (like in this tutorial). However, it is important to note that this method seemed to disable my touchscreen. Probably requires another conf file, though. OTG is working.

Hardware buttons don't work yet. Hardware buttons do work, they just require triggerhappy on xfce. Back and menu buttons are in /dev/input/event1, home, volume and power buttons are in /dev/input/event0.

WiFi doesn't work (in fact, WiFi doesn't seem to appear in `ip a` at all!) WiFi should work using the i9070 method. Not much modifications are needed. Sadly, I can't figure out how to build the kernel module :/

Audio should work using these instructions. The tablet uses TAB3_WM1811 as the name.
