Re: Driver Name visible in Device Manager!!! with no - - device

NTDEV

I don’t think it really violates any rules, as the interfaces exist to
configure ‘root enumerated pseudo devices’. However I also don’t see any
compelling reason to make such drivers pnp/wdm, (for some value of wdm,
pgv.) The argument I’ve heard in favor of using a pnp/wdm framework is that
it provides a well defined management interface. OK, but really the SCM does
too, and it is much simpler and fits the ‘kernel module’ design better.

This raises a question that I haven’t totally answered yet.
Is there a legit way of writing the equivalent of a Linux
kernel module under the wdm model ? Or are we sort of
violating the rules whenever we write a driver that only
handles imaginary hardware ?

Looks like your registry is broken by incorrect INF file. It
occurs sometimes.

PnP shows either the value from the functional driver’s INF
file or, if the functional driver is not found, then it
displays the result of MN_QUERY_DEVICE_TEXT returned by the
bus driver.

Anyway a devnode is required, and it is extremely strange if
PnP displays something without a real devnode.
