🎙️ Spent ~35 hours reverse-engineering the Apogee ONEv2 USB audio interface on Linux:
• 2 kernel patches to sound/usb/
• Vendor init sequence found via Wireshark on macOS
• Hardware watchdog keepalive daemon
• ALSA sees Playback and Capture PCMs
• Playback PCM opens — stable streaming not yet cracked

It's never too late for an ambitious goal and to learn something new. I'm reading "Linux Kernel Programming - Second Edition" by Kaiwan N. Billimoria [1]. Chapter two brought back a lot of memories. Glad that "make menuconfig" and the like are still around even after so many years I didn't touch them. Wish me luck on my journey to contribute to the Linux Kernel one day.

Luckily, the AI isn't taking over just yet, because this code doesn't actually compile. Bit it's still very close! #openai #kernelhacking
