I suspect this could be related to bug #212660 "ehci-hcd causes failed suspends on kernel 2.6.24" for which a work-around is:
echo 'SUSPEND_MODULES="ehci-hcd"' | sudo tee /etc/pm/config.d/modules_unload If possible please try this work-around and report progress to bug #212660 if successful. -- USB devices fail after suspend https://bugs.launchpad.net/bugs/252341 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
