Reading USB HID bits

A few lines to determine which audio driver is mapped to a physical USB codec

Hi! We have a shipping hardware product which is a USB composite device containing four TI 2904 audio CODECs and a TI USB hub chip. The problem we've run into is this: Windows maps the audio driver (ie. USB Device (2)) in a seemingly random fashion to the phyiscal CODECs. For example, if we unplug the device or reboot the machine, the driver mapped to the codec on physical port 1 of the hub may move to port 2. So, USB Device (2) -> phyiscal CODEC 2 in one instance, USB Device (3) -> physical codec 2 after the machine is rebooted. What we need form you is the code to determine which audio driver is mapped to which physical device, so our software can gracefully handle a reboot or reattachment to a different USB port.

Thanks!!

One programmer thinks that this may be due to the fact that all codecs power up at the same time, rather than in sequential order. What we need is the code to tell which driver is mapped to which physical hub port, regardless of the power-up order.

We would be glad to close the bidding immediately at $300 if you are -absolutely- certain you can complete the job.
