Power on with USB Plug - Huawei MediaPad T5 Questions & Answers

I would like to install the T5 as a Mediacenter in the car. Who can I modify the tablet to power on with the USB Plug? I have found the way with fastboot oem-off-mode charge 0. But when I connect to the PC, the cmd says all the time "waiting for device" any Idea?

Reconnect the USB after sleep

Connected 7.0 plus to computer, after a while it went to sleep. Pressed the power key, so it will wake. In the windows explore I can't find the 7.0 plus any more. If I don't want to pull the cable out and insert it back, any way to reconnect the USB? It shows USB was connected, but nothing in windows explore.
I don't know if this will help, but when I use usb stick, after performing copying files etc, then safely remove usb, it won't recognize a different usb drive. So I re-boot and then it recognizes all again

[Q] USB OTG Does not work anymore

Hello Gents,
I purchased a USB OTG for my 7+ last week, all was working. the USB drives works, mouse works.
But this morning, when I tried to use the same mouse/usb drives. The tab does not seem to recognized the USB, I can see the LED on the USB blinks for a few moment and then turn off. Like it's getting power but then stop.
I tried the following.
1. reboot the tab. power on , power off. No go.
2. reboot from factory default ( yes it drives me nuts, but I did it anyway) Power Volume Up. Factory reset, data wipe. No go.
3. tried a new OTG USB cable, still does not work.
I had the Tab root before, but after the system reset, it gone back to stock firmware. The only thing I can think of is I did the latest Samsung Patch after my initial test.
When I look at the "dmesg"
s5p-ehci: detected XactErr len 0/8 retry
tspdrv: ImmVibeSPI_ForceOut_AmpEnable (1)
ImmVibeSPI_ForceOut_AMpDisable...
Does anyone have solution for this problem?
Thank
P.S. these are not the OEM Samsung USB cable. But they were working before.
Also, when I plug in an portable external HDD, it does say, High power device not supported.
hi,,,
try to connect all tools to usb otg hub first before you conect it to GTab. i mean if you want to connect a flash disk or a mouse, connect them to the usb otg hub first before connect it to GTab.
for hdd, you have to connect a power supply to usb otg to make it readable on GTab. i use my old nokia charger to power the usb otg hub device.
hope it help and sorry for my bad english.
dan
edit : i use this device as usb otg hub

Greetings!
I had this issue as well, keeping track of it via Device Manager on the PC. Sometimes, it says it's the Model #, other times (depending on if you're recovering, adb debugging) it will say is "ADB Interface". I'm in need of recovery and refresh for mine, which is how I figured this part out. It's not much, but open your Device Manager on your PC before plugging it in via the 2nd USB2.0 down on the tablet. Watch it. If on the Windows side, it should pick it up as a media device or the device model number. On the Android side, if USB Debugging is on (which mine already is, thanks to the last person who had it -- I bought it from Amazon.), the charging should show up on-screen, and the Device Manager (USB Device, last one down) should see it.
I hope this little bit helped.

Computer Doesn't Recognize N20U Connected Via USB A

I can't figure this out. For some reason my Windows 10 computer doesn't recognize my Note 20 Ultra when it's connected to a USB 3.1 type A port. It's not my cables, I used them with my S10+ and they worked fine. The only way my computer will recognize my phone is if I use a type C to type C cable in the USB 3.2 type c port. Otherwise it shows up in device manager as "Samsung Mobile USB Composite Device" with a conflict and tells me the USB device malfunctioned and isn't recognized. I can't for the life of me figure out why my computer won't recognize my phone in any USB A ports.
The drivers are installed, the cables aren't faulty, and uninstalling the drivers and letting them install with PnP doesn't work. Does anyone have any idea what's going on here?

Pi Zero connected to phone (adb)

Hej,
my phone is powered by Android 10. As you probably know, to get ADB over Wifi working on devices running Android 10 you have to connect it to a computer via usb cable.
This is not very comfortable nor a practical way to go.
So i prepared a Pi Zero 2W in a way that it runs 'adb tcpip 5555' when it recognises that the device id of my phone is connected. but there is this problem that i need 2 cables right now to achive what i want.
1. If I connect the phone to my pi (any port, normal usb cable, no further powersource), the pi start up just fine but the phone isn't available in the list of the usb host controller
2. If I power up the pi with external power and connect a second usb cable with otg adapter afterwards to the phone the pi recongize the phone and begins to start adb.
3. If I try to power the pi with only the otg adapter cable with the phone, the pi doesnt get alive. There seems no current.
My Question is:
Is it possible to connect the pi with only one cable or maybe a splitter cable to the phone so the pi can draw power from the phone and also see the phjone as regular usb device that can be operated on ?
regards
rob
