Safely Remove Hardware Tray Item and USB drivers

hi

How do I prevent my usb driver from showing up in the Safely Remove Hardware Tray Item?
Is this an inf change?

thanks in advance

In case one of you is tempted to tell me to check previous postings (since this has been covered before), the reason I want to block it from showing up in the Safely Remove Hardware tray is that this bus driver exposes virtual serial over usb functionality and needs to be uninstalled after the com port driver.

I just want to block my driver from showing up in that list, but I want my driver functionality to remain the same.

I still want to support surprise remove – since resetting the usb device looks like a surprise remove.

thanks

No, this is a flag in DEVICE_CAPABILITIES, which is used in
MN_QUERY_CAPABILITIES path. Pass the IRP down, then catch it via the completion
handling, and patch the SurpriseRemovalOk flag to be set.

In IRP_MN_QUERY_CAPABILITIES, set SurpriseRemovalOK = 1.

Set SurpriseRemovalOK in the DEVICE_CAPABILITIES field for IRP_MN_QUERY_CAPABILITIES when the irp is going up the stack.

Thanks to everybody that replied.

In my bus driver (similar to toaster sample - it gets loaded when the usb device is plugged in) I added a handler for IRP_MN_QUERY_CAPABILITIES in the Bus_FDO_Pnp handler (handler for the bus itself) and catch the IRP coming back up to set the flag, as you suggested, and it works.

thanks!
