Description

It seems, during boot the UHCI driver is being loaded before the EHCI driver, which generates a warning in dmsg (see below @ 5.140022). This is related to http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9beeee6584b9aa4f9192055512411484a2a624df&id2=2b70f07343389cb474235def00b021a645ede916

Please, ignore the device descriptor errors shown in the log @ 6.500953 and later, that are caused by a wacky USB device and have nothing to do with the issue reported.
