Hi,
I had posted this issue in darwin-userlevel. I was referred here. I
searched the archives, but cudnt find a solution to this though I
found few mails referring to a similar situation.
http://lists.apple.com/archives/Darwin-userlevel/2005/Oct/msg00020.html
To reiterate and update, I am writing a CFPlugin bundle for spr532
(SCM microsystems) usb smart card reader. When I tried to open the
interface (USBInterfaceOpen), I am getting a a 0xE00002c5 ( exclusive
access and device already open) error.
One of my guess was maybe classic is holding the handle of the reader
since it has a device class value of 0 (composite device) and its
interface class/subclass/protocol is
255(vendor-specific)/0(vendor-specific)/0 . But, Classic was not
running in my machine.
Another lead I got was to create a "codeless kext" to override anyone
holding the device's handle. So, I created a "codeless kext" and
loaded it (on reboot). I still am getting the same error.
I am at a dead-end here. Any leads / guidance will be of great help to me.
The ioreg output when the device is connected and the driver the
attempts to open it is as below
