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!

does anyone knows a simple way to handle hotplug #usb devices with #libusb ?

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 #rp2040

Any LIBUSB Async (linux) experts here? I want to improve speed between usbsid and PC. Unfortunately I am running into race conditions causing packets from device to pc misalign, e.g. the callback gets called more then expected, or too late. Async send and sync on read is too slow.

#libusb 1.0.27 has been released (#USB) https://libusb.info/
libusb

It works, but everything is hardcoded. Need to add some configuration system. #streamdeck #WriteInC #libusb

Can anyone recommend a #framework that allows relatively easy cross-platform (#Android, #Windows, #Linux) development?
Needs to be able to:
- Open #USB webcam stream
- Call #ffmpeg
- Send USB vendor control transfers (or calls to #libusb)
- GUI

I really don't want to write code two times (and dislike Android app dev), but recently realized that I'd really like for my upcoming #P2Pro viewer to run on Android too.

But if there is no such thing, I'll stick to desktop only for now :/

Day 2 of my posting adventures to finally figure out what is going on with my build of #libuhd #libusb on #openbsd 

https://sourceforge.net/p/libusb/mailman/message/37796867/

 boosts would be v helpful in case anyone has seen something like this before, esp from bsd folks or sdr folks #ham #sdr #bsd
