Is there a way for an application to do a setProperty to a usb device ? I
have tried IORegistryEntrySetCFProperty() but it returns
kIOReturnUnsupported. I can do IORegistryEntryCreateCFProperty() to read a
property and that works... I tried IOCreatePlugInInterfaceForService(), then
QueryInterface() to get the IOUSBDeviceInterface and then
(*dev)->setProperty() but that didn't work. Before I open my device , I want
to be able to set some device parameters which my acquirePort() driver
routine will be able to read in order to configure some options during the
open() call.
