New Mi5s Otg Problem

[Luís Morais]

Hello,
My hardware – XIAOMI MI5S 3/64G
ROM – XIAOMI EU V8.0.10.0.MAGCNDH_v8-6.0
My problem is with OTG, connecting pen drives all seems to be OK, mouse OK, game controller also OK, but when I connect other devices such as usb telemetry radios, video capture boards like easycap or Mobius camera the devices are power on but nothing happens (seems none Tx or Rx activity). This devices work okay in other phones like zte ultra 6 or chwvi vi7. Example of good working is connecting the Mobius camera under OTG and read the SD card which are not occur in the MI5S.
Any clue about what I’m doing wrong?
Thank you.
LM

I have the same problem weeks ago with my Mi4C, and the solution i found its format my pendrive to FAT32

Thanks for your answer, but in my case:
- Pen drives fat32 - OTG OK
- sd card in mobius camera - camera power on by OTG but can't see the card contents in phone;
- other like telemetry radio or easycap power on by OTG but no data transfer between phone and devices;
Anyone with this dificulties? Hardware or software related?
