I enabled hidden devices and it was not there..However, after updating the Bios, and trying to update the thunderbolt drivers (which failed), the USB midi device was recognized and all seems OK for the time being.
Hi, I have a USB keyboard that I am attaching to the XPS 9700 laptop using a USB Type/B-->Type/C converter (the supplied Dell d20).  In device manager the keyboard used to be detected but now it is not detected.   I have researched and tried the suggestions available.   I also have a Win 10 Surface and the keyboard is detected when I plug into that laptop.    This is a recent development even though I have had trouble in the past getting the keyboard recognized under the sound devices in Device Manager.   IN the past, I would simply change the Thunderbolt port a time or two and eventually the device would be recognized and I could use it in the DAW software. I know it is not the cable.   And the TypeB-->C converter works on my other laptop. I have also tried the power management suggestions (turning off the "all sleep to save power' option for the Universal Serial Bus Controller devices. Any help greatly appreciated! -Mark
