USB OTG not working

Hello there,
unfortunately, I couldn't get USB OTG working, even though it should support it according to various spec pages.

My setup is following: LG G5 <-> USB Type C to Micro USB adapter <-> Micro USB-OTG adapter (2.0) <-> USB 2.0 thumb drive (see attached picture)
  • The light of the drive is not lighting up. So maybe the G5 isn't powering the device?
  • I've tried three different USB-OTG adapters without success. All three are working on a G4 as well as on a Nexus 7 (2012) flawlessly.
  • The USB Type C to Micro USB adapters should work as well. Charging (normal and QuickCharge) is working perfectly fine, even ADB does as it should so the data pins should be connected. However, both adapters lack D+ and D- pins for USB 2.0 on one side. This should not be a problem, though. (see attached picture)

Did somebody succeed in using OTG in a similar setup?
