I am writing to tell how I managed to solve my USB hub problems related to raspberry pi zero W, but I would still want a feedback and related help on this.
The issue was, I could not get anything recognized on the usb port of the raspberry using my OTG cable:
(without using usb hub). Some could argue that the issue might be that the OTG I made is a custom cable and it was its own fault.
But even when I connected the Usb hub (Zero4u), it recognized the usb hub, but nothing that I connected to it (a mouse, usb stick, keyboard), nothing.
Here I even power the USB hub with a separate power:
But it could only recognize the usb hub, not the USB stick you see on the picture, or anything else I connected to it. Using
lsusb
I could only get the usb hub info.
