** Description changed: + Continued in Bug #1622322. + Seems to be paired with dmesg entries like this on the trusty kernel: [24763.731054] usb 4-4.2: Disable of device-initiated U1 failed.

[ 302.833086] usb 4-3: USB disconnect, device number 4 Mainline version fyi: [ 0.000000] Linux version 4.6.0-040600-generic (kernel@gomeisa) (gcc version 5.3.1 20160509 (Ubuntu 5.3.1-19ubuntu1) ) #201605151930 SMP Sun May 15 23:32:59 UTC 2016 I also get a similar message about 'Failed to disable LTM' if I just unplug the device before the breakage occurs. I've attached lsusb before the breakage occurs (so you can see the device) from the mainline kernel. Interestingly it appears the drivers on trusty and wily/mainline are different (r815x vs r8152) yet still exhibit similar troubles. I'm still digging around to try and figure out why this doesn't seem to be working, but I was wondering if you all had any idea what might be going pear-shaped here. Thanks!
