Hi for months Linux users have been reporting random USB crashes with certain webcams. It happens randomly and mostly with Logitech webcams (which claim no Linux support). I'm pretty sure I've tracked it down to a simple pointer check before dereference but it completely crashes USB subsystems until reboot and is really frustrating. PR and explanation can be found here. Please have a look. It won't fix any race condition but at least it won't Oops the kernel. https://github.com/torvalds/linux/commit/a40519014549f60969c8e67a2fd91426db05fe04 Thank you! John Boero
