From 3342ecda3ffb059f2ffd765a71d9579f0aa036eb Mon Sep 17 00:00:00 2001 From: Sarah Sharp Date: Thu, 3 Dec 2009 11:35:59 -0800 Subject: [PATCH] USB: usbtmc: Use usb_clear_halt() instead of custom code. Make the USB Test & Measurement driver use usb_clear_halt() instead of usb_control_msg() to clear a stalled endpoint. This will allow devices to be tested under an xHCI host controller. The endpoint stall will not be cleared in the internal xHCI hardware state unless usb_clear_halt() is used.
