I have a USB-b cable I've been using for years with my m-audio keystation 88, and the one that comes with the s88 is not long enough. So my new keyboard will power on, run through the startup, then a few seconds later usb device is not recognized. I've installed the proper drivers, but nada. Is this the USB cable not working with this model? All of the USB connections are USB 3 or higher on my PC. I've got at least one USB-c as well. Only other thing I can think to try is get a newer usb-b cable. I've tried all of the things that I've found for USBs not being recognized. So what's the issue here? Did I forget something in the installation process? Is there a button or button combo I am supposed to press after it starts up? I'm grasping at straws here.
