I used it because I couldn't put redmi note 5a to edl (only fastboot) and it bricked my device. It tried to flash global (I chose it) over chinese stable and the device lost the software (for some reason)
I have the same problem using latest miui 8 developer rom (from xiaomi-miui.gr). Using betterbatterystats I found out it was msm_otg. I can't find a solution rather than rebooting after disconnecting the charger
