[Q] OnePlus One USB and OTG storage issue and TWRP topic

After a few weeks since I got my OnePlus, I'm having a strange problem. Whenever I try to copy any sort of data to/from the phone, a few seconds after task has been started I get this error

"Cannot copy file.xxx
The device has either stopped responding or has been disconnected"

Also, the OTG storage devices get unmounted randomly and notification pops up
"USB storage unexpectedly removed"

I reached the concusion (like most of you would) that maybe USB port is malfunctioning.
But here is the twist:

If I connect my phone in MTP mode while in TWRP, the copying/pasting just occurs successfully each time. Even if I mount OTG in TWRP, USB storage works as it should without any issues.

I've already tried:
-changing different ROMs (PA, CM)
-flashing stock kernel, recovery and rom
-using different USB cables
-using different PC
-changing in between MTP and PTP
-copying directly to root, folders and sub-folders

But each time, the copying and OTG storage fails while booted into OS but works normally while using TWRP
