NAME

       usb_hub_tt_clear_buffer - clear control/bulk TT state in high speed hub

SYNOPSIS

       void usb_hub_tt_clear_buffer  (struct usb_device * udev, int pipe);

ARGUMENTS

       udev   the device whose split transaction failed

       pipe   identifies the endpoint of the failed transaction

DESCRIPTION

       High speed HCDs use this to tell the hub driver that some split control
       or  bulk  transaction  failed  in a way that requires clearing internal
       state of a transaction  translator.  This  is  normally  detected  (and
       reported) from interrupt context.

       It  may not be possible for that hub to handle additional full (or low)
       speed transactions until that state is fully cleared out.
