Noticed the mgb driver for Microchip LAN7430 (/31) NIC in FreeBSD commit logs. Huh, interesting stuff: Microchip publishes so much documentation.. a “Programmer’s Guide” PDF with lots of driver pseudocode, and even evaluation board design files!

The touchscreen (both finger and pen support) on my Pixelbook has been broken for a while (the Wacom digitizer was always present on i2c but it wasn’t sending events). There was like one time where I managed to get it to work briefly by holding the pen against it in some way, but that was it. Today I took the laptop out of the bag by the middle part, squeezing the lid a bit. Aaaand… touch works now! Something was going on with wiring somehow inside the lid (not the hinge) I guess? :/

Wi-Fi not connecting (well, getting instantly deauthed due to AP-STA-POSSIBLE-PSK-MISMATCH after connecting) is apparently a relatively common problem with IoT devices. And most people seem to point to ESP8266-based ones.

Well, I’ve never had a problem with ESP, but today I’ve been setting up an RTL8711AF based device (Xiaomi qmi.powerstrip.v1) and it was failing just like that.

Turns out this device just completely fails when 802.11w Management Frame Protection is on (even optionally). Ugh. Thanks Realtek.

Wow. micro HDMI is the worst connector ever.

(well, at least this particular adapter is terrible.. or the Pi 4 grabs too hard?)
