[PATCH] USB: ehci - clear TT buffer command patch

I have a patch for a typo in the 2.6.0 kernel, drivers/usb/core/hub.c,

in hub_clear_tt_buffer, the value USB_DIR_IN | USB_RECIP_OTHER is used
for bmRequestType, when section 11.24.2 of the spec says it should
really be USB_RT_PORT, or 00100011b.

After limited testing, this change exhibited better recovery from TT
errors, here's the patch :
