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

Hardware need not be present. You can just write a driver which just
responds to your IOCTL calls but is still a kernel mode one. That will
surely appear in the Device Manager though no h/w is associated it.
I guess the device manager will be displaying all the names under
the SERVICE key of the registry. You can choose to see all the hidden
devices from the Device Mamagement menu options.

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

hI,

U are absolutely right…

<<“Hardware need not be present. You can just write a driver which just
responds to your IOCTL calls but is still a kernel mode one. That will
surely appear in the Device Manager though no h/w is associated it.”>>

I would like to know how exactly this happens…

without hardware present,how do pnp manager loads such kernel drivers…or
is it loaded by someother system components…

regards,

shiv
