Comment:
As per LP#1812561 add usb debug note for suspend debug.

   1. Please provide the output of the following terminal command: {{{
  cat /sys/kernel/debug/suspend_stats }}}
   1. If you have a graphics related issue after resume (corruption, display blank, etc.) please [[https://help.ubuntu.com/community/DebuggingSystemCrash#SSH|SSH]] into your machine and capture both /var/log/Xorg.0.log and /var/log/Xorg.0.log.old. Please attach each separately.
+  1. If your issue may be USB related, for example, disabling XHC1 prior to sleeping is a workaround via a terminal: {{{
+ # echo XHC1 > /proc/acpi/wakeup
+ }}} then one will want to use the following kernel boot parameter, and attach dmesg in full: {{{
+ usbcore.dyndbg=+p
+ }}}
