This dialog pops up when i unplug my usb device from the port. Can someone
tell me the reason for this pop-up… BTW my driver doesn’t have digital
signature.

Thanks
Sesha.

Subject: [ntdev] Win2k SCSI Miniport driver

I am working on a Win2k SCSI Miniport driver. After getting called in the
DriverEntry, FindAdapter and InitializeAdapter I am getting calls to the
StartIO routine for a Read SRB (0x28)which have a block# of 0, number of
blocks of 0 in the CDB but a DataTransferLength that is non-zero (usually
32K).

Which is correct - are there 0 block reads that have the
DataTransferLength
set or is the # blocks field in the CDB incorrect in which case do I need
to calculate the correct number of blocks using the DataTransferLength?

Thanks for any help.

It has nothing to do with the driver being signed or not signed. Check out
