Considering 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?

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!

I 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 #rp2040via @loudfpv
