Comment 22 for bug 1678477

With the kernels from http://people.canonical.com/~khfeng/lp1678477-nolpm/ , the problem seems to have returned. I got the following error on boot:

[ 1.273005] usb 3-9: new full-speed USB device number 3 using xhci_hcd
[ 11.740700] usb 3-9: string descriptor 0 read error: -110
[ 11.740733] usb 3-9: New USB device found, idVendor=1b1c, idProduct=1b20
[ 11.740734] usb 3-9: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 16.860817] usb 3-9: can't set config #1, error -110

Unplugging and re-plugging the keyboard also gives me similar error messages on dmesg. More often than not it will eventually work on one of the retries, but sometimes it will fail three times in a row and stop. I guess one or more of the other two quirks are necessary too.
