Sorry, we do not support doing SetProperty from user space on the USB
stack nubs. You may file an enhancement request.

Is there a way for an application to do a setProperty to a usb

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.
