Hello first sorry for my bad english, second i just got an older Asus Z380KL (runing Android 6.0.1 latest update from Asus) and its working fine for the most part. I just cant connect it to my PC (Windows 7/10) using USB. When i plug it in to my PC in device manager i dont see any new device but the Tablet is charging.
The tablet is in charging mode and i cant switch it to MTP. In Setting>Storage there is no option to change the USB mode, i dont get any notification in the pull down bar, in Developer menu i enabled USB debuging and tested the option to switch the USB configuration but if i change to MTP,PTP or RNDIS it always says Charging. I know the USB connector on the tablet is OK just tested my OTG cable and connected a mouse and it was working. Also i used 5 diferent USB cables that work when i try whit my Phone. Also tested all my USB2 and USB3 ports on my PC and laptop.
If anyone can help i wold be very grateful
Edit: Just tried it on Ubuntu 16.04 Live and MTP is working fine, Tablet connects i get the popup in the status bat saying i can pick if i want charging, MTP or PTP but on Windows 7/10 i cant get it to work its always in charging mode and i cant change it.

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

I have the same error but when I reboot my Tab, it's ok, before reboot I do not disconnect USB from my tab!You can try!
I've had my OPO for a little over 7 months now. My issue began when I had my desktop at a friend's house and plugged my phone into a USB 3.0 port to grab some videos off the phone when the phone suddenly shut off and would not turn back on. I thought it was bricked somehow but after leaving it plugged into a USB 2.0 port for some time, the charging screen came on and I was able to turn the phone on, but since then both OTG and MTP/PTP transfer doesn't work. If/when the phone is plugged into a computer, it gives an error and Device Manager shows
"Port_#0001.Hub_#0004 Unknown USB Device (Port Reset Failed)" and I'm not only able to charge the phone with one out the dozens of micro usb cables I have. I've tried several cables and a handful of different computers and OSs (Windows 7,8,8.1,10, Ubuntu 15.04, Kali Linux) all to the same result.
I'm running COS 12.1-YOG4PAS3JL, rooted, and have TWRP installed. The phone doesn't show up when in Fastboot mode or the bootloader either. Nothing changes when I disable or enable USB Debugging as well. With DriveDroid if I set the USB system to "Standard Android" the phone reboots and that seems like the closest I've been able to get to any kind of progress. I've gone through unbricking threads as well as Googled until my fingers bled but I'm yet to find anyone with a similar situation where the phone isn't bricked, the micro usb port isn't broken, I can't pick between MTP or PTP mode (USB Connection just says USB is now disconnected), and I'm not running a custom ROM. I tried replacing the micro usb on the phone so I now know that it wasn't that that's been messed up but I'm not sure where to go from here. Any suggestions or help is greatly appreciated.
My Verizon Galaxy s6 doesn't get detected at all by my computer AT ALL. I've tried different cables, PC's, USB Debugging etc.. It just charges that's about it. I looked in Device manager etc on all the computers I've plugged it into and it doesn't show anything being connected. Also I even tried a OTG Usb flash drive that doesn't get detected by the phone neither and the LED on the usb doesn't light up. Only thing I haven't tried is to force put it in MTP I don't know how to do that, i'm on 5.1.1 not marshmallow so I don't think I have that option and I can't update the phone to 6.0.1 because I don't use the phone on Verizon's network to OTA and the phone won't connect to my computer so I cant update it that way. The phone charges good when connected to the wall outlet. The only thing I can think of is maybe the charger port is damaged in someway that is not allowing the phone to detect a computer is connected to it which is why I never get a MTP notification. Before I do surgery on this phone and attempt to replace the charger port do y'all know of any reason to why it won't connect to the pc or is there anything I can do to force MTP?

I just tried this still doesn't work
Smart Switch should be able to update it for you if you don't have service. Has to be in MTP mode though. Enable Developer options by going to About Phone -> tap Build Number a bunch of times and then change the USB connection type in Developer options. I think Smart Switch installs drivers. If none of that works maybe its a driver or OS problem.
When I plug in my Nvidia Shield K1 into my computer it only charges.....
My old K1 was recognised by my computer immediately before so I don't know why this one won't work?
Please note these things.
1. I have tried a different cable and connector
2. It was purchased second hand and bootloader is already unlocked with TWRP installed.
3. Have installed all necessary drivers on computer
4. Have put tablet into developers mode
5. Have selected MTP on developer options
6. Nothing shows up in device manager
Have you tried with another PC?
Any notification on the Shield, that it has been connected by USB? And if so, select MTP (selecting MTP in Developer's Options doesn't always work on some devices).
You tried other USB ports on the PC? You said you tried another cable and "connector", so maybe by "connector" you mean the USB port on the PC? Also, don't use a hub, connect directly to the USB port on the PC.
If none of this work, and never did on this 2nd hands device, you may have a damaged USB port on the Shield.
Try going to Developer options - Revoke USB debugging authorizations. That has worked for me in the past. I would doing it with the USB disconnected then reconnect.
I need to connect to this tv box through adb, but adb doesn't even detect it. I'm using Ubuntu on a laptop.
USB debugging is allowed in developer options, the connection type is either file transfer or charging, trying to select any other mode (picture/image transfer) doesn't work, it goes into charging mode.
I tried using only WiFi, nothing. Tried connecting the box by USB to the laptop, nothing. Tried plugging in an ethernet cable from the laptop to the box, laptop can't get a connection going.
Has anyone managed to do it?

If you have windows on your laptop, try using MyPhoneExplorer and connect to MyPhoneExplorer Client on H96.
