Review on 🔌 Amazon Basics 10 Port USB 2.0 Hub, 5-Pack: Efficient Connectivity Solution for Multiple Devices by Dave Wheeler

Seems like a pretty simple thing but hiding here was a very annoying problem for me. I use this to control very expensive complex devices. I need to type two USB serial ports and a regular keyboard. I used it and everything was fine. Eventually I discovered a very fatal bug that caused all file I/O to be disabled on my Debian Linux. This happened as a result of plugging this hub (empty or loaded with the aforementioned peripherals) into a USB port (normal 2.0). Then suddenly everything went into an I/O error because the Linux kernel couldn't read anything (commands, anything) from anywhere (filesystem, serial ports, etc.). I would stop the power button, position the hub where I wanted it, and restart (and it worked fine at the time - just turning it back on was problematic). Obviously there is a bug in the Linux kernel and it should never happen. This may have been fixed in the latest Linux, but a more obvious solution that works great is a different hub. Strange issue, but I wouldn't recommend this Linux hub on older laptops.
