I am able to find instances of my driver via
IOServiceGetMatchingServices().  Next step is to open a connection
using IOServiceOpen().  However return code is kIOReturnNoMemory.  I
have a plist entry for IOUserClientClass:IOUSBUserClient.  For some
reason it seems IOKit cannot find IOUSBUserClient class.

Can someone help me w/this ?


I assume you are writing a driver for a USB device. What kind of communication do you want to perform with your USB driver? Any reason why you are not using the standard user client for communicating with USB devices and interfaces? See IOUSBLib.h for details.
