Hello,
I have got Galaxy Tab A (2017) SM-T380, but it seems I cannot use OTG. Every time I try to connect an adapter, I'm getting this in notification area:
"High-power USB device connected"
"Cannot access to this device. Connected device needs external supply"
It would be much appreciated if you can point me to the right direction. Is there any custom kernel that make it possible to use OTG with the device or any other workaround?
Thank you very much.

Why don't you do what it asks? You need to connect an external power supply. Devices such as disk drives need external power.
The device itself cannot provide enough power.

Hello everyone.
I am currently modding Samsung Galaxy Tab 2 7.0 for car instalation and everything seems to be great except I have problems with two things:
1) As the tab will be also my main music player I would need an USB host from time to time (check: http://www.expansys.si/samsung-usb-adapter-for-galaxy-tab-series-no-30-pin-to-sd-slot-229630/ ). It would be hard to switch that adapter with power supply just for the time I need to stick USB in it so I am asking if anyone knows if it is possible to have both active at the same time: power supply and USB host? Or if anyone has some other interesting idea how to transfer data to tablet asap from time to time? Please note that it will be really hard to reach it when installed.
2) Since the tab has back camera (which is useless to me in cars interior) i was thinking if there is any possible way to get that camera out of the tab with some extender or something? I've been looking at the interior of a tablet and the camera doesnt look to be attach in any other way than just a flat cable. Any ideas?
Thank you guys for your help in advance!
Make love, not war <3

It sound like this will be a permanent installation.
Instead of €22 for an adapter, I'd rather use a breakout and hardwire:

This will also allow you to wire the earphone output also.
Yes, with many devices you can charge and do host mode at the same time.
It's mostly a question of convincing your device to play nicely with a non-standard operation.
You can just bring out the USB leads or hardwire in a hub for more options, like a keyboard.
I'd use a DC converter circuit board hardwired instead of a cigarette lighter adaptor.
Something like this, maybe: http://www.lightobject.com/LM2576-High-Input-7V40V-Switching-5V-Power-Module-Regulator-P549.aspx
I think somewhere in the Tab 10.1 forums, someone figured out the proper wiring for a powered USB host adapter. 90% certain that would also work on Tab 2 7.0
Hello everyone. I bought a nexus 10 a few days ago from a friend,he barely used it. However i cant seem to be able to connect the device with a usb flash disk. I bought the otg cable from ebay,and it works with a mouse like a charm. I tried connecting 2 flash usb and external hdd that get power externally..They all give me the same result at nexus media importer: after waiting like 5-10 secs "connecting..." then "waiting for media...",i get
"timed out in waitDeviceReady()". I can't seem to find anything about it on google. Any help/advice please?
Also,the usb/hdd have a small led light on them which is supposed to "blink" when they are connected and the connection is ok. When i connect them to n10, they "blink" at first for 2-3 secs, then they stay on/off.
I had better luck with non-Fat16/32 formatted OTG storage devices when I installed "USB OTG Helper [root]" although you require root. Just a suggestions.
With USB powered harddrives (not self powered), I read a number of posts indicating people had issues due the N10 not being able to supply the power requirements. Some even mentioned that their HDD worked but only when the N10 had 75% or higher charge.
Hi
I have Samsung Galaxy Tab 4 10.1 LTE SM-T535.
Does anyone know a way or a device that will enable charging the tablet and connecting it to another device via OTG?
I have tried several devices/usb splitters in order to simultaneously charge the tablet while connecting it to an additional device via OTG. None of them worked. However, I succeeded to achieve that only once: The tablet was in charging and then when I connected it to another device, the tablet remain charging and I was able to use the connected device. So I know that i should be possible. Unfortunately, I failed to reproduces the same result.
Hi,
I have a problem with connecting my Android device (Samsung Galaxy A5 SM-A510F (2016)) via a ethernet adapter and a OTG cable with LAN.
I bought an ethernet adapter and an OTG cable on ebay.
I rooted my Galaxy A5 successfully.
I downloaded the apps "BusyBox" and "Ethernet" (the app "Ethernet" should enable all settings needed to get USB ethernet). This app does not come with any drivers!
I also tried to connect my device using an active USB hub.
However, you obviously need the ethernet driver on the smartphone (which is not yet installed on Galaxy A5).
Does anybody know how I can get this driver?
Or does something else cause the problem?
Are there some better apps for connecting a device to LAN? (for example one which already comes with ethernet drivers)
Thanks for your efforts!
Best regards,
Simon
Hello everybody. Asking for help and suggestions. Maybe LENOVO representative take notice. Have secondhand yoga book. Resolved almost all problems but micro USB port. First of all, charging device died out. Find 30-watt charger with QC 3.0 and charge now working perfectly. Next tried to connect mouse, usb hub and usb dongle. Each time got DEVICE NOT RECOGNIZED message. Got error in device list.
But......tried to connect external HDD with noname HDD box and it connected. Connection may work to copy, install files or disk may disconnect randomly.
Tried system restore, tried to change drivers ( intel drivers for chipset not avaliable now) with no luck. Think problem is with low port current, but even small mouse and dongle make error and non-SSD HDD work 9 times out of 10. Have anybody experience problems with connecting devices to micro USB port?
Tried 3 different OTG cables and OTG micro USB to USB dongles. No luck.
Maybe the port is corrupted or desoldered

I did change it with the warranty I had. I had the same problem and did not want to fix by myself as the warranty was still active
