We have two x4s. Both updated to 9. OTG usb works on one perfectly and not at all on the other. Both used to work. If 9 broke usb, it should be broke on both. Can't see any differences between the two devices. Making me crazy.

Thank you for posting. This is interesting, allow is to help. Are you getting an error message whenever you plugged in your OTG USB?
