Also there is NVIDIA Miracast Audio [NoDB] among monitors. It's virtual device and strangely has "Audio" in its name. Probably comes with the latest Nvidia drivers. Does not appear in windows display properties.

And one more thing, I've just noticed all my USB 3.0 devices show their current speed as 2.0, for example AgeStar 3FBCP1:

Device Properties:  
    Device Description   Запоминающее уÑтройÑтво Ð´Ð»Ñ USB  
    Device ID   1F75-0611  
    Device Class   08 / 06 (Mass Storage)  
    Device Protocol   50  
    Serial Number   20140808  
    Supported USB Version   3.00  
    Current Speed   High (USB 2.0)  

I've tested linear speed with 2.5" SATA disk and it was ~120 MB/s linear read and ~230 MB/s buffered read which indicates USB 3.0 mode.

 

Same speed is shown for USB 3.0 cardreader and flash drive.

1) Thank you, we'll add S19C200 in the next AIDA64 beta update due in a few days from now.

2) Since that virtual device has no identification values put in the EDID block (like model name or vendor name), we cannot add it to the monitor database.

3) We've seen such issues before. It is simply because the USB controller of the device fails to set the USB field indicating the current USB rate in use properly. We unfortunately cannot fix that from software.
