   8 commit deefd24228a172d1b27d4a9adbfd2cdacd60ae64 upstream.

  10 Raydium USB touchscreen fails to set config if LPM is enabled:
  11 [    2.030658] usb 1-8: New USB device found, idVendor=2386, idProduct=3119
  12 [    2.030659] usb 1-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0
  13 [    2.030660] usb 1-8: Product: Raydium Touch System
  14 [    2.030661] usb 1-8: Manufacturer: Raydium Corporation
  15 [    7.132209] usb 1-8: can't set config #1, error -110
  16
  17 Same behavior can be observed on 2386:3114.

  19 Raydium claims the touchscreen supports LPM under Windows, so I used
  20 Microsoft USB Test Tools (MUTT) [1] to check its LPM status. MUTT shows
  21 that the LPM doesn't work under Windows, either. So let's just disable LPM
  22 for Raydium touchscreens.
