I am not writing a user client. I have specified
the "IOUserClientClass:IOUSBUserClient" key-value pair in the driver's
plist. I understand that this is a default class that can be used if I
choose not to write my own user client. Is this correct ?
Is there something else that needs to be done in order for IOKit
to "find" the IOUSBUserClient class ?
