Ok.
Regarding the DEVICE_ATTR* macros. So I have attributes with same
names for different device types. I may be able to identify the device
types and deal with the correct attribute based on that, but for
example the attribute "active" with alternate modes is writable, but
with cables it's not. How do I handle those?
