I found at Aliexpress some USB-C to USB-A Adapters which seems to be ok for connecting USB-Sticks, Wireless mouse or HDD to it. But they all mention OTG!?!

Imho this is needed for some phones to connect device, but I don't know that it connection with laptops.

Are that the right adapters?

Hello @starbright_,

 

OTG (or On-the-go) adapters essentially allows mobile devices to connect to USB and mass storage devices while also allowing them to be connected to a host computer acting as a mass storage device. 

 

Essentially, OTG adapters were invented so that mobile devices could connect to USB devices but they work with your laptop as well. Just make sure you purchase a reliable adapter with good reviews as I've had plenty of bad connection consistency experiences with third party USB-C adapters purchased through online shopping.

 

Kind regards,

Eddy

As far as I could conclude from the price this adapter are passive, just changing the shape of the interface connector, right?

  It is wise to always use  specifications and knowledge instead of price to draw accurate conclusions.   It is likely that the adapter is passive. see the wiki article at the link below this line.

Checkin this closer I assume that this OTG Adapters will support only USB-2.0.

Don't find a pinout scheme for USB-C OTG but I found something with respect to USB-Micro. That has not just the 4 known USB 2.0 pins but 5 - there is an extra "Sense pin". If this is grounded, it signals the phone  to be a "USB Master" (as a phone is usually some kind of a slave).

My guess (not sure) this pin will be ignored by PCs - but I don't found any proof for this theory.

Haven't found any USB3.0 OTG pinout til now.... (Maybe ithis "Sense Pin" is pin 7 (Ground for signal return))
