GripNews🌗 給軟體開發人員的 USB 指南
➤ 擺脫核心態束縛，從使用者層級駕馭 USB 裝置
✤ https://werwolv.net/posts/usb_for_sw_devs/
本文旨在消除軟體開發者對 USB 驅動程式開發的恐懼。作者以 Android 手機的 Bootloader 模式為例，說明開發者無需深入核心態（Kernel Mode）撰寫晦澀的程式碼，即可透過 Userspace 應用程式與硬體進行溝通。藉由介紹 `lsusb` 指令查詢設備識別碼（VID/PID），以及運用 `libusb` 函式庫實作設備熱插拔監測，開發者能更直觀地掌握 USB 設備的通訊原理，降低硬體介接的開發門檻。
+ 終於看到一篇不談複雜匯流排細節，而是以實務應用為導向的文章了，這對想進入硬體開發的軟體工程師非常有幫助。
+ 對於需要編寫自定義通訊協定的人來說，`libusb` 確實是比直接寫 Kernel 驅動更好的起點。

Lorenzo MinieroConsidering the Windows editor for my #DNAfx GiT Core won't run on neither Wine nor any VM, I've spent the past few days trying to reverse engineer its USB protocol, in order to write a basic editor for Linux of my own. It's been interesting so far to play with #libusb (I can already kinda talk to the device), especially coming from the perspective of a network developer, but I have some doubts on how #USB communication works in general: is there anyone around here that can clarify a few points?
Orhun Parmaksız 👾Today I discovered a pretty cool utility for listing USB devices! 🔌
🌸 **cyme**: A modern and cross-platform lsusb!
🔥 Displays manufacturer, serial number, speed, current information (mA) and more!
🦀 Written in Rust!

LouDI could really use some #libusb experts opinion on getting this function faster. The round trip takes 100~200 uS and is just too slow, but async read causes race conditions.
A single write takes 30 uS (async). Ive already removed all overhead on the device side code but the time stays the same. #tinyusb #rp2040

#libusb 1.0.27 has been released (#USB) https://libusb.info/
onionIt works, but everything is hardcoded. Need to add some configuration system. #streamdeck #WriteInC #libusb
