 WDK may also provide the headers for WinUSB.

-# Dealing with self signed drivers:
+# Installing WinUSB driver:
 
-Installation would be straightforward were it not for the USB Driver
-that needs to be setup. The driver itself is only a WinUSB inf file
-(no actual driver), but it still needs to be signed.
+Installation automatically happens for Windows 8 and Windows 10 because the panda
+firmware contains the USB descriptors necessary to auto-install the WinUSB driver.
 
-Driver signing is a requirement of Windows starting in 8 (64 bit
-versions only for some reason). If your Windows refuses to install
-the driver, there are three choices:
+Windows 7 will not auto-install the WinUSB driver. You can use Zadig to install
+the WinUSB driver. This software is not tested on anything before 7.
 
-- Self Sign the Driver.
-- Disable Driver Signature Verification
-- Purchase a certificate signed by a trusted authority.
-
-Since self signed certificates have no chain of trust to a known
-certificate authority, if you self sign, you will have to add your
-cert to the root certificate store of your Windows' installation. This
-is dangerous because it means anything signed with your cert will be
-trusted. If you make your own cert, add a password so someone can't
-copy it and screw with your computer's trust.
-
-Disabling Signature Verification allows you to temporarily install
-drivers without a trusted signature. Once you reboot, new drivers will
-need to be verified again, but any installed drivers will stay where
-they are. This option is irritating if you are installing and
-uninstalling the inf driver multiple times, but overall, is safer than
-the custom root certificate described above.
-
-Purchasing a signed certificate is the best long term option, but it
-is not useful for open source contributors, since the certificate will
-be kept safe by the comma.ai team. Developers should use one of the
-other two options.
-
-**Note that certificate issues apply no matter if you are building
-  from source or running an insaller .exe file.**
-
-Some people have reported that the driver installs without needing to
-disable driver signing, or that visual studio correctly sets up a
-temporary signing key for them. I call witchcraft because I have not
-had that happen to me. The signed certificate is still the correct
-thing to do in the end.
-
-Windows 7 will not force driver signing. This software is not tested
-on anything before 7.

 # ToDo Items:
 
-- Get official signing key for WinUSB driver inf file.
-- Implement TxClear and RxClear. (Requires reading vague specifications).
 - Apply a style-guide and consistent naming convention for Classes/Functions/Variables.
 - Send multiple messages (each with a different address) from a given connection at the same time.
 - Implement ISO14230/KWP2000 FAST (LIN communication is already supported with the raw panda USB driver).
