Accessing a device in a WDM driver

NTFSD
1

I have written a WDM driver for a specific device using the inf “sample.inf” in
which i mentioned a device id for the device
In this driver sample.sys i want to access the memory of other device present in
the same system with different device id
Is there any possible way
if yes kindly provide me the same

Thanks in Advance

Attach to the driver for that device, create an IRP requesting the required action, fill it in, and send it to the driver. If the device driver supports your action then everything is copasetic. If the driver does not, then basically you’re up a creek without a paddle, unless you own the driver. Then you always add the IOCTL that you need to do the task.
