Re: After waking from suspend, USB devices are not recognized (Ubuntu 17.10)

Not powertop, but yes tlp. Very interesting. I will uninstall and see if
that solves the problem.

Another observation I just made: If I suspend the laptop with USB devices
plugged in, they are still detected when I restart.

I guess I could work around by leaving some small USB device plugged in
(one of those wireless mouse things) but obviously that's a real hack.
Still, the observation may be a hint as to what's going on or what I might
look at next.

I will disable TLP and report back.

Do you run powertop or tlp on your laptop? Sometimes those can cause
issues with the USB ports.

After waking from suspend, USB devices are not recognized (Ubuntu 17.10)

2017-11-23 Thread Michael Shiloh 
Hi,

I noticed that my old mouse didn't work all the time, and figured it was
time to replace the mouse. Then I had trouble programming some Arduinos,
and figured I had a bad Arduino. It wasn't until my system failed to see a
thumb drive that I finally realized the common element here: After waking
from suspend, no devices plugged in to the USB ports are recognized.

$ uname -a
Linux x1 4.13.0-16-generic #19-Ubuntu SMP Wed Oct 11 18:35:14 UTC 2017
x86_64 x86_64 x86_64 GNU/Linux

Hardware details are at the end of this mail.

Here is the system in its failed state:

$ lsusb

I'm not much of an expert with USB and udev, so I did a bit of reading and
learned about udevadm. After a reboot, when USB is working,

$ sudo apt-get install udevadm

shows activity when I plug or unplug a USB device. After a suspend,
nothing.

I googled expressions like "usb not recognized after wake from suspend" and
didn't find anything useful.

I don't know enough about this part of the system to know where to look
next. What do you suggest I do next in order to determine where the problem
might be?

System info below.

Thanks in advance for any guidance,
Michael
