Hi,
I am aware of the pc/sc subsystem in the OS. I have the driver bundle
placed in /usr/libexec/smartcardservices/drivers. When i plug-in my
device (spr532), the driver bundle loads, but is failing when it tries
to open the interface. that is my problem. I found from forums that
some other app maybe holding the handle. Hence, I went for the
"codeless kext". But, still I am facing the issue.
Under this situation, if i run "pcsctest", it fails in the
"scardestablishcontext" itself since the driver is not successfully
loaded. Hence, the deadlock for me. I sure shall post it in the cdsa
list also, if I can get a lead/solution to this.
