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

Might me because its entry is there in the registry. Check to see the
properties of the device where you can find a message like ‘not working’.

cheers

Hi Naveen,

Correction:-Device Name Visible in Device Manager With No device

Thanks for ur response…But to be noted is, I had installed driver with no

Hardware for it…

Only if I have some hardware,and if the conflict symbol arises, it’s fine
I
can try to allocate different resource which doesn’t conflict with other
hardware…

But I don’t have hardware installed…But still it shows the Device name in

the Device Manager…My query is how the Device name is getting registered
even after rebooting,when there is no hardware present…

ie,in a pnp function driver should get loaded only when the Pnp Manager
creates a PDO for a device…When no device is there,where is the chance
for
a Function driver…and Getting the name of the device in the Device
manager
list…???

regards,

shiv

hi sheshagiri,

I would like to know, can a device Manager display a device name without
an actual hardware being present(though with a conflict symbol when I load
just the driver for the device)Just because it’s name is present in the
registry…If so,wouldn’t it should display all the names under the SERVICE
KEY in registry in the Device manager too…???

regards,

shiv

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.
