If you’re running OpenWrt on a Raspberry Pi 5 with a USB-to-Ethernet adapter based on the Realtek RTL8153B chipset, you may have noticed that the adapter stops working after a power outage. It works fine after a manual unplug/replug, but never comes up on its own after a cold boot. Here’s why, and how to fix it permanently. The Problem Many RTL8153B-based USB Ethernet adapters (including models from TP-Link, Ugreen, and others) use a dual-mode design. When first plugged in, they present themselves as a USB CD-ROM drive (product ID 0bda:8151) containing a Windows driver installer. A special kernel driver called r8152-cfgselector is supposed to intercept this, switch the device to Ethernet mode (product ID 0bda:8153), and hand it off to the r8152 network driver. ...
After upgrading Proxmox from version 8 to 9 (or after a kernel upgrade), Intel iGPU passthrough for Frigate running in a Docker container inside an LXC container suddenly stopped working. OpenVINO would detect the GPU but hang indefinitely when trying to use it, forcing fallback to CPU inference. System Configuration Hardware: Intel NUC12WSHi5 (12th Gen Alder Lake with Intel UHD Graphics) Host OS: Proxmox 9 with kernel 6.14.11-4-pve Setup: Frigate running in Docker container inside LXC container Goal: Hardware acceleration using Intel iGPU (OpenVINO + VAAPI) Symptoms OpenVINO detects GPU but can’t use it Critical kernel errors in dmesg FFmpeg VAAPI errors Root Cause The kernel upgrade broke the i915-sriov-dkms module that enables Intel iGPU virtualization and SR-IOV support. DKMS modules need to be rebuilt when kernels are upgraded, but this didn’t happen automatically, leaving the GPU driver in a broken state. ...
How I Fixed My Kobo Forma USB Connection on Arch Linux When I first tried connecting my Kobo Forma to my Arch Linux setup, it was a nightmare. The device would charge fine but either never show up, or it would disconnect after 20–30 seconds, usually in the middle of copying files or installing KOReader. After hours of trial and error, I finally pieced together a reliable workflow. Here’s a complete guide to help anyone else who runs into the same Kobo + Linux headaches. ...

Exposing Local Development Servers Securely with Tailscale Serve As developers, we often need to expose local services to other devices—whether that’s for testing on a phone, sharing work-in-progress with a teammate, or running an integration test across machines. Tools like ngrok have been the go-to solution, but there’s a simpler, more secure option if you already use Tailscale: Tailscale Serve. In this post, I’ll walk through how you can use Tailscale Serve to make a local Dockerized Rails + Ember setup available from your laptop, without editing your docker-compose.yml. ...
The Tapo C200 cameras insist on contacting public NTP servers to sync their clock. If you block them from reaching the Internet (a good idea for security), the cameras will slowly drift out of sync because they ignore the DHCP-provided NTP option. The solution is simple: run an NTP server on your OpenWrt router and transparently redirect the cameras’ NTP traffic to it. Step 1 — Enable NTP on OpenWrt Make sure your router itself syncs time and provides it to LAN devices. ...
