Hello, nice to "see" you here again and thnx for your post with the info about the USB Composite device.
Of course I failed to find any device with this Hardware Ids and Device Instance Path - neither in Device Manager nor with AIDA.
Next is just for your information - may be one of these days it might come in handy for you.
There are several records in the Registry with "Keyboard receiver" (KBR). According to them I must have the version of KBR 1.1.0.09060 (201309060) installed on my PC with appid EP0000308232 (this can't be find now even with the Google search - while EP0000323846 can be) and install date 20140109 (reminder - I bought my VAIO Tap in April 2014). In the folder C:\Program Files\Sony\Keyboard Receiver\ there are two files - KeyboardReceiver.dll (7 Sep 2013, 74kB) and Version.txt (which contains as I could guess some log records of my update attempts and the ProductGUID={A54FF7A1-896D-4419-9228-A4E177E37EDC} - but this is a unique code of the software allegedly installed on my PC only).
You wrote that in your case it was VID_054C - this Vendor ID belongs to Sony
Registry search for PID_0872 gives nothing. I have only PID_06D9 - this is Sony IR remote control. While yours VID_054C&PID_0872 belongs to an "unknown device" - according to http://drivers.awdit.com/hwid/usb/vid_054c/
At this point I have to surrender - being not a developer I do not know what to do next with this info.
If someone with good expertise ever comes across this info of mine and will be able to suggest something in order to fix the trouble - it will be just great.
BR
