Quick'n dirty fix to get both USB3 and Bluetooth running every time - do automatic xhci_xcd unload / load cycle until no error messages in syslog is detected:
Needs: 1. custom compiled kernel with xhci_xcd as module, not builtin. 2. Upstream kernel with device ids for 168c:0036 or recompiled modules from https://github.com/Satius/mod_0cf3_311f source. 1. Install Logmon from here http://code.google.com/p/linscripts/wiki/logmon 2. Copy logmon.sh to /usr/sbin 3. Create executable shell script with following contents in /usr/sbin: sudo touch /usr/sbin/logmon-run.sh sudo chmod +x /usr/sbin/logmon-run.sh paste in: #!/bin/bash rmmod xhci-hcd modprobe xhci-hcd 4. modify /etc/rc.local, add before line exit 0 /usr/sbin/logmon-run.sh /usr/sbin/logmon.sh "/usr/sbin/logmon-run.sh" -m "Error in firmware loading" /var/log/kern.log& ======== Indeed, additional minor bug found for HP ProBook 450 G1, unfortunately no time to go in deeper checks - if USB3 is disabled in kernel, then after suspend / resume all USB ports are dead. Until suspend everything is working perfectly in USB2 mode. So no way to live without USB3. -- 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/1237296 Title: 168c:0036 [Acer Aspire E1-572] ath9k QCA9565/AR9565/QCWB335 Bluetooth works sporadic Status in “linux” package in Ubuntu: Triaged Status in “linux” source package in Saucy: Triaged Status in “linux” source package in Trusty: Triaged Bug description: Hello, I got myself a brand new Acer Aspire E1-572-54204G50Mnkk, because of the shine new Haswell hardware I choose to install Ubuntu 13.10 Beta 2.
