I have a Samsung I9305 running rooted stock Android 4.4.4 with Xposed framework.
I used to be able to use USB OTG Storage devices flawlessly.
However, recently, none of them mount. I've tried third party root drivers such as Paragon, but it didn't help. I've tried drives formated in FAT32, exFAT, ext4, NTFS and HFS+ (for the latter I tried using the Paragon driver.) None of them work now.
OTG mice and keyboards still work, so that leads me to think that this may be a software problem.
Is there anything, short of a full firmware restore, that I can try to make this work?
