How to gGet USB ProductID by DEVICE_URI

[keens312]

Hi Michael,

My application nees to send data to printer by USB on Mac OSX 10.5.

This application is started by launch agent with DEVICE_URI argument passed from CUPS filter. (Filter does not know USB Product ID detail).

Then this application will figure out the USB PID by the DEVICE_URI.

Do you have any good easy way to get this?

It seems taht I have to migrate part of usb backend code to this application.

Thanks
Keene
