How can I find out the device name and the OBEX interfaces from a USB device?

In a shell-script (or Perl) I need a subroutine that returns for all my USB devices, their device names, and, if available, their respective OBEX interfaces. I managed to get the device names and - with obexftp --usb - the obex-interfaces.

How can开发者_Python百科 I find out which device belongs to an OBEX interface number?
