+1 Having the same problems here :-( Solution in post #6 and post #28 are not working
Symptoms: Mac working with normally with ubuntu 17.04 It seems that when I plugin one usb mouse I have at home this f*up the system and I can no longer use the mouse, trackpad, keyboard :-( System is running as I can ssh to it from another computer. Rebooting ubuntu does not help. Actually the system cannot shutdown properly, I have to turn it off (long press on the power button) updated to kernel image 4.12 to no avail Problem might also be due to putting the computer to sleep (I read somewhere that it was not flawless on my mac, but I use suspend a lot) I found different posts on the web reporting various USB problems (with camera, drive, etc) But no solution yet -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1668105 Title: xhci_hcd module turns off usb host controller on boot Status in Linux: Unknown Status in linux package in Ubuntu: Confirmed Bug description: So we know this xhci_kcd was always shit in that it turns off the console usb keyboard for long running computers and that it on abrupt termination of Linux puts usb in a 12x slower mode. It is buggy, it was always buggy, and its getting worse. With Linux 4.8.0-37, this crappy software decides to halt the host controller on boot, ie. turn off the console keyboard preventing any boot. I cannot think of any situation where anyone would want their host controller halted. This is MacBook Pro 2015. So, it's already broken in UEFI-grub as it always was, ie. every key press takes 8 seconds, but you only need two, so you can boot in 16 s. I tried to disable the xhci_kcd crap by using kernel parameter noxhci_port_switch or modprobe.blacklist=xhci_hcd neither which works. Because it has crap in UEFI, the computer will not boot any external hard drive or usb fob. The only thing that works is Apple rescue that gets rid of the xhci garbage, and the boot os x immediately after that. So the log output xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command xhci_hcd 0000:00:14.0: xHCI host not responding to stop endpoint command. - and a bit later: xhci_hcd 0000:00:14.0: Assuming host is dying, halting host. xhci_hcd 0000:00:14.0: HC died; cleaning up This clown programming of Linux has to stop. Why would anyone ever want their host controller halted? --- ApportVersion: 2.20.3-0ubuntu8.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: foxyboy 5662 F.... pulseaudio /dev/snd/controlC0: foxyboy 5662 F.... pulseaudio CurrentDesktop: GNOME DistroRelease: Ubuntu 16.10 HibernationDevice: RESUME=/dev/mapper/C89-SWAP MachineType: Apple Inc.
