SHORT QUESTION:
Will a usb(male) to hdmi(female) adaptor work with NVIDIA Sheild?
Full Question:
I am trying to connect my surround sound hifi with my nvidia shield separately to my TV. Would a usb to hdmi work on the nvidia shield to pass the audio through. Any issues with drivers?
End Goal:
To connect 4k to TV and separate 5.1 audio to hifi box
Currently Tried:
HDMI splitter - it only chooses the lowest audio output which is the TV (2.0) not the required 5.1
Notes:
Hifi box supports hdmi passthrough but only at 1080p
Hifi box (2012 pioneer, INPUTS: HDMI, OPTICAL COAXIAL)

I have Raspberry Pi 3 plate with connected USB to UART (COM) converter.
The power led on the USB stick is ON.
I can not find the converter in Windows Device Portal.
In both: connected and disconnected states I see just two UART related records in Device Manager:
(ID:ACPI\BCM2835\0, Class:System, Manufacturer:Microsoft, StatusCode:25165834)
>BCM283x Mini UART Serial Device
(ID:ACPI\BCM2836\0, Class:Ports, Manufacturer:Microsoft, StatusCode:25182218)
>ARM PL011 UART Device Driver
(ID:ACPI\BCM2837\4, Class:System, Manufacturer:Microsoft, StatusCode:25165834)
Also I use git diff between saved device lists and there is no difference between the case I connect USB stick and disconnect it.
Where can I see the device in the list?
UPDATE
Here I print all found devices:
First you need make sure your USB to UART (COM) converter is supported on Windows IoT Core. Please check the hardware compatibility list. The CP2102 USB 2.0 to TTL Module Serial Converter is supported.
I use CP2102 USB to UART Bridge Converter and it also works. Use the SerialUART sample can list two device: one is on-board PL011 UART Device and the other is mine.
From device portal:
I use webcam-capture(java api) to get video stream from a usb camera, it work fine.
I want read a usb device descriptor(store some private information), i find out that should install WinUSB or libusbk as a driver to the usb devices. and it test ok, read the descriptor success (by libusb_control_transfer api)
the question is:
befor I install WinUSB, the usb camera is a camera device in the windows device management list. the LibUSB work fail, can't open the usb devices, the error number is -5, means entrypoin not find
after I install WinUSB, libUSB api work ok, but the webcam program can't open the usb devices, it is a universal usb device in the windows device management list.
is there some way the webcam work ok, at the same time, i can read the usb device descriptor use libusb or use other something?
i tested on windows 7 and windows 8, have the same problem.
thanks.
Sadly this is not possible because each of your applications needs a different driver. The only way this can work is if you use libusb and build you own capturing api on top which is quite complicated. As long as webcam-capture can not read the data you want to know about the webcam I am afraid this is not possible.
Is it possible to enable HDMI audio when running an UWP app on RPi 2? There is sound when I connect speakers via the 3.5mm jack, but I would prefer HDMI audio.
Apparently it's possible, but I don't know how to do it on IoT Core: https://www.raspberrypi.org/documentation/configuration/audio-config.md
HDMI audio is not supported on Windows 10 IoT for the Raspberry Pi. The only option available is the 3.5mm headphone jack.

I'm trying to get a device running embedded linux V-2.6.31 to automatically recognize when a Huawei 3G usb stick is plugged to it, run usb_modeswitch, and communicate with the module.
it seems that usb_modeswitch doesn't work well in a system that has mdev, since the path /dev/bus/usb is only being created with udev.
I found a script that create this path and enable usb_modeswitch to work properly.
now, all i need is automation of this process, e.g., when plugging the 3G module, hotplug will first call my script, and then usb_modeswitch.
the problem is that when plugging the 3G module nothing happens when the enumeration is done (the hotplug wont run), see trace:

I'm not sure what is wrong, is there something i didn't enable? is there a KO that i need to load in order for it to work?
Thank you in advance!
I have an Arduino-compatible board with USB Host Shield. It is connected to an Acer A100 Android tablet running "Ice Cream Sandwich" (Android 4.0.3) with Kernel 2.6.39.4. (The tablet has a USB micro connector and does not support USB HOST mode and therefore cannot connect directly to a USB accessory device.)
This picture shows what I have been able to do successfully (but with my tablet in place of the phone).

I would like to find an example of using an Android tablet connected to a USB Accessory (such as a keyboard or flash drive) via Arduino.
Connecting the USB accessory to the Arduino's USB micro connector (using an external power supply) does not work.
Can anyone provide me with such an example?
Theoretically it should work, I haven't tried it yet though.
Arduino should act as the middle man and should relay signals both from your tablet and the accessory.
What code are you use?
This is: adk_release_20120606?
And what board are you use SeeeduinoADK?
I use board Seeeduino ADK, but unfortunately I could not make it work in USB accessory mode. My board work in only ADB (MicroBridge mode). See my work example
My tablet is Ainol Aurora with Android version 4.0.4 (CyanogenMod 9)
