I think Diamond supports USB host.

I saw this picture in the service manual:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
In this picture,we can see it is using an USB card reader.So I am sure Diamond supports USB host.At leaset ,the hardware supports.
But we can also see an AC adapter, so maybe Diamond can not power the connected USB devices.
If an external AC adapter is connected , maybe it really supports some USB devices.But if an external AC adapter is needed, it is not very useful.

yes there have been several posts about the same thing in the forums
and nobody ever been able to get host outside of the bootloader
and even the ppc devices which do support usbHost require external power
usb is 5volt 0.5amps and
watt == volt * amps
so that mean it would have to be able to supply 2.5Watt out of the usb port
and thats more then most handheld devices can manage

How to enable USB debugging for remote control of phone without a screen or digitizer

I have a rooted Note 4 with TWRP. My screen and digitizer are destroyed so all i have is the mainboard. I've connected with USB and can enter my password, I can take screenshots and see them but I can't enable USB debugging and ADB isn't able to help. Without using ANY onboard phone inputs outside of the Power, Home, Menu, Back and volume buttons. How can I enable usb debugging so that I can get in and remote control my phone with something like teamviewer or adb?
Thanks guys

Got it stumbled blindly into team viewer using a usb keyboard with the OTG adapter and got it.

My XT1092 won't charge (video)

I haven't touched the phone for around 6 months. Now that I was trying to charge it the phone goes into a loop of turning on, displaying the charging splash screen, vibrating and turning off:

(can't post a direct link)
When unplugging the usb cable I get this image for a brief moment before it goes off for good:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
It's unlocked, but on an original rom.
Is that a known problem and is there a way to resurrect it?

I fixed it by:
Connecting the charger
Holding down the power button and volume down at the same time, for 30 second or so to get into the fastboot menu
Inside that menu I selected Recovery mode
While in Recovery mode I was able to charge and rebooted normally at 7% charge or so
I got the hint from reading the comments under some youtube video (search term: moto x2 charge).

USB charging but no file transfer

Some weird issue with my phone - I cannot connect it to Windows 10 (tried on two computers) using USB type-c cables laying around.
When connecting to USB on PC - the phone is charging, but there is no USB notification in the notification bar, where you can choose an option. When I try to search for USB options - they all grayed out.
Cables working, same for USB - checked wy my wife Motorola G7.
Tried to set a default mode in development options - still no luck.
Tried to connect a mouse - works.
No root, no custom firmware.
What to do? How to fix it?
This is a development option:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And that's what I see when connecting to a PC

There was a really annoying background noise when connected to my IEMs (kz zsn pro), and also had volume issues with my ath m40x. I will try the Samsung dongle tomorrow.

Samsung dongle works much better. Audio quality is very good, but it also has issues with the volume (works Ok connected to a Windows PC). I will keep it for my sensitive IEMs and buy an external dac/amp for the over ears.
