Hi,
this is not really on topic for libusbx but since I know the people who hang there are very well versed in this I figured this is one of the places to ask, since this has been discussed before [1]. Of course tried to google for this but could not really find a definite answer. Background I'm writing a small cross platform library in Java to access HID devices, similar to HIDAPI, but with JNA so that C-tool chain and non-OS native libraries are not needed. I've got the prototype working in Mac OS X and Windows and I'm working on the Linux next. The problem I would like offer to the library users a 'path' to the HID device that persists from run to run unless the device is plugged to a different port. I windows I think the path I pass to CreateFile() is the what I want and can use but on OS X the penny has not yet dropped. I see that HIDAPI uses kIOHIDTransportKey retrieved fromt the IOHIDDevice but that seems to change from run to run. I have not looked into the Linux yet but I expect that could be easy. Of course it would be great if the path would be human readable so that it can be displayed (after formatting perhaps) on the UI and be intelligible to users. This can't be very unique question and I was sure somewhere some one has published a solution but I can't find it.... br Kusti [1] http://sourceforge.net/mailarchive/message.php?msg_id=29300228 This e-mail may contain confidential or privileged information.
