4.19-stable review patch. If anyone has any objections, please let me know.
------------------ From: Kai-Heng Feng <kai.heng.f...@canonical.com> commit deefd24228a172d1b27d4a9adbfd2cdacd60ae64 upstream. Raydium USB touchscreen fails to set config if LPM is enabled: [ 2.030658] usb 1-8: New USB device found, idVendor=2386, idProduct=3119 [ 2.030659] usb 1-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 2.030660] usb 1-8: Product: Raydium Touch System [ 2.030661] usb 1-8: Manufacturer: Raydium Corporation [ 7.132209] usb 1-8: can't set config #1, error -110 Same behavior can be observed on 2386:3114. Raydium claims the touchscreen supports LPM under Windows, so I used Microsoft USB Test Tools (MUTT) [1] to check its LPM status. MUTT shows that the LPM doesn't work under Windows, either. So let's just disable LPM for Raydium touchscreens.
