Help required on Surprise Removal in XP (NDIS5.1) when writing NDIS-WDMdrivers

Hello,

I am writing a NDIS-WDM (USB ) driver for NDIS5.1 (XP). I used the
sample from Eliyas.

I saw the mailing lists and set the NDIS_ATTRIBUTE_SURPRISE_REMOVAL_OK
bit in the call to NdisMSetAttributesEx from MiniportInitialize
function. And I implemented the additional MiniportPnPEventNotify
function also.

When I plug-in the cable, Windows loads my driver. But the "System Tray"
icon for "Safely Remove Hardware" appears. When I remove the cable, I
get a call to my PnPEventNotify function with SurpriseRemoved event set.
There is no pop-up error message as per XP standards.

But, I was under the understanding that if the SURPRISE_REMOVAL_OK bit
is set, even the "tray icon" does not appear.

Please help me in making sure that my understanding is right. If I am
wrong, what have I done wrong in the driver that this is not working?

Any pointers or any kind of help is greatly appreciated.

Thanks in advance for the great help.

Best Regards,

Cable removal is not device removal. You must indicate the media disconnect
instead.

 

Unless this is _the_ USB cable

 

Cable removal is not device removal.

Yes, I was about _Ethernet_ cable

 

I am talking about a USB Device. Sorry if I was not clear about this.

Since it is a USB Cable, there is no cable disconnect event possible as
the driver gets a halt call.

I am talking about the "Safely Remove Hardware" ICON in the SYSTEM TRAY.
This is supposed to have gone once the NDIS Attribute for
SURPRISE_REMOVAL is set by the driver. But this is not the case here.

Please help me in getting the solution for this problem.

Any pointers or any kind of help is great.

Thanks in advance

I don't know why no one is replying.

Does this mean no one has faced any problem of this sort?

Eliyas, Are you there? Can you please help me?

Thanks in advance
