David HJ Posted January 19, 2017 Share Posted January 19, 2017 Has anyone experience this situation, connecting a digital piano to pc and get "unknown usb device (device descriptor request failed)"? This problem persist after I uninstall it in device manager and reinstall it. How can you fix it? But interestingly, it works properly in another windows 10 laptop. Below are the detailed logs I got from pc and laptop when connecting the digital piano to them. During the failing connection, I get 4 events in event viewer: Event 420: (This happens as I uninstall the device in device manager) Device USB\VID_0000&PID_0002\5&15C311E1&0&5 was deleted.

sslyutov Posted January 19, 2017 Share Posted January 19, 2017 What model do you use? If your instrument has class compliant USB MIDI controller then there is no need to install any third party driver, Windows already has it. Did you try to ask Casio customer support?

David HJ Posted January 19, 2017 Author Share Posted January 19, 2017 (edited) I'm using px-850. In the manual it does says that there is no need to install any other third party driver. And since it can automatically install driver in another pc, I think you are right. I haven't consult the casio customer support. I'll do it now. Thanks for advice! I've contact a customer representative. He says since the pc has recognize the digital piano as an "unknown usb device", meaning they have establish physical connection. He suggest me to configure the software to recognize it. But the software's manual says the MIDI connection should be established automatically prior to the software configuration. Do you have any other idea? Edited January 19, 2017 by David HJ Add result Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted January 19, 2017 Share Posted January 19, 2017 Your software should have a midi settings section which allows you to assign which midi input and output device's the software will use. Casio USB Midi will show up in the list of available devices. What is the name of the software you are using? Quote Link to comment Share on other sites More sharing options...
David HJ Posted January 20, 2017 Author Share Posted January 20, 2017 (edited) Yes, but the Casio MIDI is not shown in the input list. I'm using FL studio. Edited January 20, 2017 by David HJ Quote Link to comment Share on other sites More sharing options...
sslyutov Posted January 20, 2017 Share Posted January 20, 2017 I do not have a straight answer for you. Since keyboard is recognized by other computers - there is nothing wrong with it. I have a few guesses. 1) Try to connect to different USB port on your computer. 2) Once the keyboard is connected to the computer try to update the driver through the control panel. 3) Check whether all Windows updates are installed on you machine.

David HJ Posted January 20, 2017 Author Share Posted January 20, 2017 Thank you! I've tried these three ways and they don't work. Quote Link to comment Share on other sites More sharing options...
sslyutov Posted January 21, 2017 Share Posted January 21, 2017 In Device Manager I see my PX in the list of Software Devices as two entries of CASIO USB-MIDI. FL - Options->Settings on tab MIDI you should see it there. FL, Studio One and others - they all show it as CASIO USB-MIDI. There are no unknown devices in the USB section of device manager when PX connected to the computer. I checked it on Windows 10 Quote Link to comment Share on other sites More sharing options...

Thanks! From this log. The system does not get vendor id. I assume that 07CF is the CASIO vendor ID. This more looks like a hardware (firmware) failure. If that is true more likely it is a subject for a repair , since normally firmware cannot be programmed on the customer's side. Quote Link to comment Share on other sites More sharing options...

David HJ Posted January 21, 2017 Author Share Posted January 21, 2017 Thank you both! sslyutov, your description is exactly what I see in another PC. But in this PC, there is only the "unknown device". And one more thing. I remember that, initially, this PC could recognize the Casio MIDI when I first installed windows 10. But after using it for a while and also having some other software installed, the problem arose. So, I'm not yet sure whether it's a compatibility issue or firmware issue.
