Hello, I have a Line 6 KB37 midi keyboard/sound controller that I am trying to get running in Windows hosted in Parallels from my Mac. The device is recognized and works great in the mac, it is also recognized in Windows (when I connect it to the Windows VM) as a sound device and the drivers install fine, but in device manager it's reporting: --------- Location: Port_#0001.Hub_#0001 This device cannot start. (Code 10) The I/O device reported an I/O error. ---------- The device stays powered on when switched to Windows but blinks in an error state so I don't think it's a driver specific problem. The documentation states that it must be a directly connected USB port (specifically not through a hub) so I'm wondering if something about the Parallels mapping makes it think it's connected to a hub (particularly given the error message referencing a hub). I have tried: - Installing/uninstalling drivers numerous times in both windows and mac - Forcing the device to connect only to Windows in the Parallels config - toggling USB 3 support on/off in Parallels config - confirming latest firmware and drivers on device - rebooting both machines several times And many combinations therein, all to no avail...anyone else had issues like this? I'm running: El Capitan 10.11.6 Windows 10.0.14393 Parallels 11.2.1 (32626) Thanks
