Hi Greg, Here's two patches for 3.14. There are buggy USB devices that don't enumerate under xHCI because they expect a 64-byte Get Descriptor request before the Set Address control transfer. David Moore has a USB 2.0 webcam that exhibits this behavior: http://marc.info/?l=linux-usb&m=135879694716380&w=2 These patches change the way USB 2.0 devices are enumerated under xHCI, to try the Windows enumeration scheme first. The USB 3.0 device enumeration scheme is unchanged. This should allow these buggy USB 2.0 devices to enumerate under xHCI. I've tested this code with USB 3.0 hubs and mass storage devices, and many different USB 2.0 devices (webcam, headset, ethernet, serial, mouse, keyboard, etc). They all work, so these patches are ready for wider testing.
