[nvmewin] Is NVMe Generic Devices supported?

[Angelo Brito]

Hi Iuliu,

I haven't seen any commands. No write were sent to my controller other
than the MSIX configuration. Not even the Admin Queue's registers. I
suspect that for some reason windows NVMe Driver is dropping off my
controller after the PCIe configuration and windows events wasn't of
much help.
The events reported:

This pages suggest it is a hardware problem tough it works fine on Linux:
