I have a USB Webcam (Logitech C920), which (when attached) sometimes slows down my whole computer to less than 10% of the regular speed. I'm not only talking about boot times; which could be explained by the BIOS trying to boot from a USB “drive.” Instead the boot devices selection is slowed down significantly. It takes up to half a second to change the entry with the arrow keys, usually I can’t notice any delay.
Just waiting and booting into the OS (tried both Windows and Ubuntu) works, but is also so slow, that i unfortunately never managed to get a working shell. As soon as I disconnect the webcam it’s as fast as usual again.
I work in IT, but can’t explain this but I’m curious as to what it could be?
I can’t recognize any patterns when it does this and when not, but I don't change anything in my setup.
