My platform only runs a 3.8 derivative, though, so I now have also cherry-picked the BESL patches that went in since then to make sure they don't break things. I had problems on one device until I found the XHCI_BLC fix Mathias sent out this morning, so you should pick that one up first. (Without it LPM doesn't break completely but seems to assert resume for less time than the HIRD defines, so the device sometimes gets confused and resets. I can't figure out how BESL is really supposed to work since the XHCI spec from 8/14/12 where it's supposedly defined doesn't seem to be publicly available.) -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
