ADB / USB Debugging - MTCD Android Head Units Q&A

Ok, so these devices have two USB host sockets hanging out of them on wires. But we also know that there is a "password" to enable USB debugging.
I've tried using a USB-A plug to USB-A plug cable for hooking up USB debugging, but of course, the USB port on the device is in HOST mode.
Anybody know how to tell the USB mode to switch to slave?

[Q] Powered USB Hub Setup

I am trying to connect my NVidia Sheild to a powered usb hub with no luck at this point.
Heres what I'm using:
Powered Hub
USB to Ethernet
OTG to USB
Male to Male USB
So I am taking the OTG to USB and connecting it to the Sheild OTG port. From there I have a Male to Male USB connecting the OTG to USB to the Powered usb hub. When I do this I can see that the Sheild's power light is orange which indicates to me that it is getting power and not acting as the USB Host for the Hub?
I did notice when I tried to use an air mouse directly with the OTG to USB it works as it should but not when it's connected to the powered usb hub instead, then nothing works (just charging). Also my ethernet adapter doesnt work via the powered usb hub or the OTG to USB.
BTW this whole physical setup worked just fine (plug and play) with both android MK808 and MK908. I was surprised that the Sheild isnt picking this up as well.
Can anyone tell me if I have incompatable hardware and if so what is compatable? Also I do not have ROOT access to the Sheild...yet, could that be the issue?
Many thanks in advance.

Force USB Host Mode

Client device has USB-A connector, how do I "force USB host mode" so I can use USB-A to USB-C cable instead of using OTG adapter?

usb debugging permission

I have a device but the screen is broken, I don't see any pictures but the device is alive, there is a little light on the black screen, I tried to connect to the PC, it worked but I had to unlock the phone first.
and the essence of my question is how do I access my pc via usb debugging? Before usb debugging, there was a request for permission from the cellphone but my screen was broken, how do I do that or is there software that automatically allows usb debugging to be allowed
help please
you could try MHL HDMI multiport adapter and connect TV

Question Teyes CC3 USB Debugging not working?

I went to developer settings and turned on USB Debugging.
Went to USB mode and turned on File Transfer
Tapped the 3 dots at the top right of developer settings and chose the second option.
Now I have the USB harness connected, which gives me a USB cable, but it's female so it doesn't plug directly into my computer. I used a USB-A to USB-C adapter on that cable, then used a USB-C to USB-C cable to connect to my laptop.
But I can't get adb devices to recognize it. I've tried every combination of the "three dots" menu and USB transfer mode, but nothing works.
How do you get USB debugging to work on this device? I've been using wifi, but USB would be much better for what I'm doing.
And maybe more importantly, how can I get fastboot to recognize my laptop?
Should work. Try a new cable without the adaptor.

But the cable that comes from the headunit is usb-a female. How can I plug that into my laptop without an adapter?

You'd have to get a new cable that plugs in directly. It's the only thing I can think of. I got it to work on mine, with the second option on the 3-dit menu ...
