I have a simple test program that uses libwdi to install libusbK for a mass
storage device. It works great! (although I haven't actually tried talking
to the device using libusbx yet...)
Then to get back to the mass storage device driver (USBSTOR.sys) all I have
to do is right-click on the file and select "uninstall" and when the dialog
pops-up select a checkbox that says something like "delete driver files as
well". Then I just had to "scan for new devices" and it picked up
USBSTOR.sys again and "mounted" the drive. So why the need, as you say, to
embed the original driver for the restore part?
And I hear that you are saying that if the driver was non-WHQL it would
lead to a prompt? I don't have any known non-WHQL devices to test with but
that's something we need to look into.
