My expectation is that kernel will figure out what to load first on its own. What HCD stands for in your message? USB hub is connected to native USB 2.0 port on motherboard with Z370 chipset. Sincerely, Nazar Mokrynskyi github.com/nazar-pc 24.04.18 11:04, Oliver Neukum пише: > Am Dienstag, den

I've tried to bisect kernels from 4.13 to 4.14 and didn't find the reason. Then I found that with upstream 4.13 the issue is still present on Ubuntu 18.04, so there should be something more than just a kernel. Eventually, I found that issue is somehow related to USB hub I use for my periferals

With kernel 4.16-rc5 it is still happening to USB sound card, Android phone issue was probably related to something else and is already fixed. Very annoying to unplug sound card after each reboot, any ideas why this might happen? Sincerely, Nazar Mokrynskyi github.com/nazar-pc 13.02.18 01:26,
