In addition to adding WCID descriptors, this PR changes bDeviceClass
from 0xEF
to 0
. This means that we are no longer attempting to use the Interface Association Descriptor (IAD) method of implementing a composite device and are instead using the simpler bDeviceClass = 0
method.
We previously used bDeviceClass = 0xEF
which indicated IAD, but we hadn't actually implemented the required descriptors. This worked on Linux and macOS but did not work on Windows. With bDeviceClass = 0
things work on all three operating systems without any additional descriptors.
Add Microsoft OS 1.0 descriptor for the DFU runtime interface.
The CDC interface is recognized by Windows as a serial port already. This change makes the DFU runtime appear as a WinUSB device.
