Re: How to create minidriver on OpenSC

Does your token work with `pkcs11-tool --test --login` and your configuration?

You need to make debug_file an absolute path, otherwise the
application uses some home directory which may be quite obscure in
some cases. opensc-minidriver.dll is loaded into the applications
memory space, say iexplore.exe, for example. You can attach to that
process and set a breakpoint in some minidriver function.

for OpenSC, you need to modify the registry so that your token is
recognized by the OpenSC MD, see
https://github.com/OpenSC/OpenSC/wiki/MS-BaseCSP-MiniDriver-(for-Windows-XP,-Windows-Vista,-Windows-7)

for PIV, you may need to disable the Windows' builtin MD for PIV.
(disable smartcard plug&play)
