Arch Linux - implementing USB Hotplugging and Kernel Module Interaction
I've been working on this all day and I recently switched to I'm reviewing some code and I'm sure I'm missing something obvious here, but I'm running Arch Linux with kernel version 6.5.1, and I've been working with a frustrating question with USB devices not being recognized properly when plugged in. I've noticed that when I connect a USB drive, it sometimes fails to show up in the system. In the logs, I see the following errors: ``` [ 1234.567890] usb 1-1: device not accepting address 3, behavior -71 [ 1234.678901] usb 1-1.1: new high-speed USB device number 4 using ehci-pci [ 1234.789012] usbcore: registered new interface driver usb-storage ``` I've tried several troubleshooting steps: first, I ensured that my system is fully updated using `sudo pacman -Syu`. I also removed and reloaded the `usb_storage` module with the commands: ``` sudo rmmod usb_storage sudo modprobe usb_storage ``` However, the question continues. I tried different USB ports and even different USB drives, but the scenario remains. Additionally, I’ve checked the `dmesg` output to look for any clues, and it sometimes shows repeated failure messages for devices that should work. I’ve also added a udev rule to change permissions for the USB devices. My rule in `/etc/udev/rules.d/99-usb.rules` looks like this: ``` ACTION=="add", SUBSYSTEM=="usb", MODE="0666" ``` Despite this, it appears that the devices still do not mount automatically, and I have to manually execute `mount /dev/sdb1 /mnt/usb` after they show up in `lsblk`. I'm curious if anyone else has encountered similar issues with USB hotplugging and if there are any specific configurations or kernel parameters I should be checking or adjusting to resolve this question. Any help would be greatly appreciated. What's the best practice here? I'm working on a CLI tool that needs to handle this. Am I missing something obvious? For context: I'm using Bash on macOS. What are your experiences with this? This is my first time working with Bash LTS. Any ideas how to fix this?
