Hello,
we recently get into trouble when running our driver and vShield
Endpoint Thing Agent driver (vsepflt.sys) on one machine. The
vsepflt.sys driver fails to initialize at boot time, saying that a call
to WskCaptureProviderNPI returned STATUS_DEVICE_BUSY. This error status
is not listed in the documenation and looking the function in
disassembler (I also looked at WskRegister) reveals no obvious reason to
return such a NTSTATUS value.
When we attempt to load the vsepflt.sys driver manually, it initializes
and works without any problem.
I am quite unsure how to track down the cause of the problem, so I
highly appreciate any suggestions or shared experiences.
Our driver does not use WSK in any way.
Best regards
Martin DrĂ¡b
