Just run Zadig and select your device (you may have to click on Options
-> List all devices). Then select the driver in the list and click the
Install/Replace driver button.

Are you hot plugging a device?
libusbx does not support hotplugging of USB devices. That's something we
plan to add to v2.0.
If you are hot plugging any USB device on Windows with the current
libusbx, I'm afraid you are on your own, because this mode of operation
is not supported.

Not entirely surprising if that device was just plugged in. If that's
the one you have a problem with, then please run a test with the device
plugged from the start, and send us that log.
