It tends to be vendor drivers / vendor patches. Getting frustrated that my changes aren't applied just to see that the vendor decided to hardcode a field or dynamically patch the device tree in undocumented ways is what usually ge

This is a valid point a friend brought up as well. There's no reason all of this is enabled except for keeping the config simple. I only recently learned about `make tinyconfig` though which should let you creating a absolutely minimal

Descriptors also were kind of a mystery for me until I realized that they're just a binary structure with a fixed format that the host reads and interprets. The device descriptor is easy enough to get right as it doesn't have too

ADB uses libusb or WinUSB directly from userspace too yeah. On Windows you still need a .inf driver though because the WinUSB driver isn't getting loaded by default for Android devices because they're lacking the MS OS Descriptor

dfu-util actually also just uses libusb under the hood! Any class or device that doesn't have a driver baked into the OS can be implemented like this. And if you'd need the DFU functionality in a different application, you may be

Arguably all these other subsystems shouldn't be in the Kernel either but that's a different topic :) There are quite a few benefits to doing these things in userspace over the Kernel, not really necessarily just because of the co

By default it uses a pixel-perfect font (the one that's included in ImGui) so anti-aliasing will not do anything but make text look blurry. If you don't like the default font, it's super easy to change it though. Just go into
