I'm new to USB development on OS X, and have a bit of a dumb
question to ask.
I have written a fairly extensive library in Java to synchronize
PalmOS devices (ref: http://www.jsyncmanager.org), and I'm trying to
write some JNI code to permit USB access on OS X (on most platforms
we use the javax.usb API, but this isn't available on OS X yet. I
own the SourceForge project to port javax.usb to OS X, but decided to
start here as a quicker, easier into to IOKit and USB on OS X).
I've gone through the documentation and the examples from Apple,
and have come up with a quick JNI-based plug-in which will detect
when I plug my Tungsten C into its dock and press the synchronize
button.
Unfortunately, I want to make this a bit more generic, so it
will work with any PalmOS-based device. And the problem is that
there are at least four different vendor ID's and at least 21
different device IDs for PalmOS-based devices.
In my current test code, I'm building a CFMutableDictionaryRef
to handle the device matching, but from what I can see it is only
possible to configure it to match vendor ID/device ID for one
device. If I'm reading the documentation correctly, it's not
possible through the default implementation to set multiple keys with
the same values, correct?
I'm trying to think through the best way to accomplish my goal,
and would like some advice. Is it better in this case to:
0) Just match against every USB device, and then read the vendor/
device IDs inside my run loop, ignoring anything I'm not looking for, or
1) Build my own dictionary which is smart enough to match
against any valid combination of vendor/device IDs?
Thanks in advance for any light anyone can shed on this issue!
