Clear Feature Endpoint Halt should reset the data toggle even if the
endpoint isn't halted. Host should manage to clear the host side data
toggle to keep in sync with the device.
Test by sending a "3 data packet URB" before and after clearing the halt.
this should create a toggle sequence with two consecutive DATA0 packets.
A successful test sequence looks like this
ClearFeature(ENDPOINT_HALT) - initial toggle clear
DATA0 (max packet sized)
DATA1 (max packet sized)
DATA0 (zero length packet)
ClearFeature(ENDPOINT_HALT) - resets toggle
DATA0 (max packet sized), if clear halt fails then toggle is DATA1
DATA1 (max packet sized)
DATA0 (zero length packet)

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
