Hi,
I hope this is the right list for me to post this query. I am trying
to create a matching dictionary from the Info.plist for my CFPlugin
bundle for my usb smart card reader(SPR532). When the Info.plist
contains only one element of matching VID/PID, I am able to
successfully match the device from the code. But, when the Info.plist
contains an <array> of values for both the vendorID and ProductID key
item, The IOServiceGetMatchingServices function is not giving any
matching device. Is it possible to add an array of VIDs/PIDs to
generate my matching dictionary. I tried creating two arrays for the
key "kUSBVendorID" and kUSBProductID". What am I doing wrong here. Any
lead in this line would be of great help to me.
Attaching the code snippet I am using
