I've got a hardware platform (setup as host) which it's got a USB2.0/3.0 Micro type B female port.The system is definitely capable to detect and interface USB3 devices (can see in the embedded OS the USB3 and USB2 HUBS).
But in order to plug standard USB3 devices with a "normal" Type A connector I had to use this adapter.
The problem I've got is that all USB3 devices I'm plugging in are detected as USB2 ones instead. I tried different devices as cameras and memory sticks with same results.
I need to understand how an UBS3 device is detected over an USB2 one, I'm trying to dive into the spec and I'm no able to find a clear answer easily....
My initial guess is that this adapter is changing something in the physical layer that makes the USB3 device be detected as USB2...
- Would it be possible that the adapter is causing this problem?
- What can change at the physical layer that an USB3 device is forced to be detected as USB2?
Any ideas/clues will be appreciated.
