IRP_MN_QUERY_LEGACY_BUS_INFORMATION

hi all,

'am getting the following IRP_MN_QUERY_LEGACY_BUS_INFORMATION in my
PnpDispatch Routine. It’s a system IRP & after browsiing through this list
I found that I should just complete it… without changing the
Iotatus.Status field. it’s working fine…

But soon after this my IRP_MN_START_DEVICE is called & I get null
resources in the Irp. Also no other IRP is sent before this…

what could be the problem…??

Please help me out of this…

thanx,

SP.

Did you ever find an answer to this? I am experiencing the same issue, with a driver for an ISA bus device on Windows 10, getting null pointers for the resources in the Start_Device event.

Nice. Neceoposting to a 19 year old thread… the OP for which aid not identified, and who received no answer.

Mr. @smack847 …. Start a new thread if you have a question. Like the forum rules say.

Thread locked.
