Hello,
I have a SM-T580 with Android 7.0 that is working well. However I would like to connect a thumb drive or other peripherals.
I have tried with two different ONTG cables, but the device refuses to recognize or even power anything.
Am wondering if I am missing something here.
Anybody successfully using one of these in USB host mode?
Thanks,
Pete

I bought a SM-T580 this weekend and took it into work. My previous tablet as an Acer B3-A20 Iconia 10. I used an OTG cable from Best Buy to connect an HP wireless keyboard & mouse combo on the Acer. Today, I tried it with the SM-T580 and it worked.

Thanks for the info. In the meantime, I have discovered that this is actually a hardware problem, since the tablet does not connect to a PC, either. Now, Samsung Canada doesn't want to touch it since I bought it in the U.S. I opened up the tablet, and tried heating the USB connector contacts a bit, and that fixed it, for a while. Now it has gone bad again, so I sent it out to get the connector changed.
Thanks everyone,
Pete
work with cheap otg cable (amazon) here good.
i have tested mouse/keyboard and usb storage.

I have a hannspree sn10t1 tablet.
The tablet does not have a usb port but does have a miniUSB port.
So i wanted to connect a keyboard to it ( i got a tablet case with a keyboard in it) and got a usb adapter as well.
But it seems its not working.
At fist i thought that the adapter was defective, but i got a second one and it still does not work.
What can i do?
I tried connecting different stuff on the sub adapter and it does not show anywhere anything pointing out that there is something on usb connected.
I want to use a 3g stick as well.
What is wrong ?
Is it the software or the hardware?
Same problem
Hi,
I have the same problem.
Did you manage to get this sorted?
Thanks

I had my 7.7 for some time and about 2 days ago i've bought a cheap chinese usb otg cable from some shoup around here. I thought it would be as simple as pluging it in and connecting some usb stick like i've done with justabout all usb otg stuff i previously owned. But it doesn`t do anything. I`ve tried other usb devices, the tab simply doesn`t power them at all. I`ve also disasembled the cable and measure it, everything is fine. I`m on stock ics 4.04, also tried a couple of kernels, it just doesn`t work.
Has anyone encountered such a problem.? Damn weird....

errrr....I think I misread your issue and specific item...
sorry!
Still great though!
The usb otg cable is just a plain simple usb cable with a 20kilo ohm resistor placed between 2 pins on the galaxy tab 30pin connector. That's about all the things inside the actual cable. When you plug it in, the tablet should figure out that the 20k resistor made contact with the pins and an accesory was connected. Mine doesn't. The cable is fine, i think there's something wrong with the tablet. Doesn't it supossed to power on whatever you insert on that usb port? Because i can't get those 5v on the port.
I don't know if it's a software or hardware problem....

what file system is your USB Stick using? try formatting the stick to FAT32 and see if its a file system issue
have you tried using another OTG cable? I'm also using a china knock off bought for 4 bucks, running stock ICS and it detects most of the thumb drives I attached to it
thanks for the replies but the situation is kind of different in my case.
In order for the tablet to read what kind of filesystem you have on a usb mass storage device (stick, hdd, whatever) it must first power it on and then attempt to access it. In my case, it simply doesn't power on. So, it doesn't matter what kind of file format it has. Also, if i plug a mouse/keyboard, it won't work either.
I thought that maybe it's a broken wire inside the connector, so i took it apart and measured each pin. The otg adapter is fine, it should do the job. I've also tested on another samsung tab and it worked straight away. It seems there's something wrong with my tab. However, other then this, the 30 pin port on the tab itself seems to be working fine.
My Windows 8.1 PC would not recognize my Shield Tab with the supplied USB cable. Charges fine, though. However, the Shield Tab is recognized with either cable from my Samsung Note 2 or LG G Pad 8.3.
Anyone else experience this? Looking for feedback before contacting Nvidia.
My tablet is not recognised on Linux either, whereas my nexus 7 2013 was. It did have Franco kernel installed, which might make it mount the file system better than stock.
I am able to see mine in windows and my linux vm

Thanks for the feedback, guys. I appreciate it. I'll contact Nvidia and inquire about a replacement USB cable.

Actually, I stand corrected. My tablet is visible in LInux in MTP and PTP mode.
Have you tried the usual tricks about swapping USB sockets, and checking your Connected Hardware in Windows.
I also have USB Debugging on, if that makes a difference.
The Shield cable is the same as any other Micro USB cable, so if you have another one lying around for another phone, give it a go first before going to the hassle of contacting Nvidia.

Thanks. It's definitely a bad cable. I've tried USB cables from 3 other devices and the Shield tab is recognized by my PC with each of them.
I've now purchased THREE USB OTG straight cables (not Y) that did not work with my Shield Tablet... Is there some sort of trick i don't know about? Some special kind of OTG cable i need to buy? Some setting i need to enable for it to work?
I've tested the cables both with usb keyboard, mouse and various properly formatted USB drives - none detected at all. They dont work either with my Nexus 4 phone or Nexus 7 2012 tablet (but i suspect those models dont even support USB OTG, so doesnt say much).
Can anyone point me to a straight USB OTG cable that actually works with the tablet?
Are you running the latest OTA , Android 5.1? The OTG is broken in this version. Try plugging in the cable while tablet powered off the booting up. You won't be able to charge tablet until reboot though.

Man, I updated while traveling for 45 days!!! Loss of OTG for thumb drives, hub connection, camera image off load, wired Ethernet....what a loss!!!any word on when they will release software that at least makes it fully functional again? Plus the constant app optimization every boot cycle..I am hoping their self driving cars and self cooking ovens and make believe cities get better attention!

According to their website they expect an update by the end of the month that should fix these issues.
Online I've seen people using a USB OTG cable on the Samsung Galaxy S6 but when I try to do so on a Verizon model it does not respond to keyboard or mouse input.
Has anyone else tried to use USB OTG?
I used my OTG cable to hook my verizon s6 to my external hard drive last week. Everything worked fine. Check your language and input setting maybe?
Well the problem is that there is no response at all. For example when I connect the mouse to another phone via the cable the mouse light turns on, connecting it to the S6 does nothing.
Are you on 6.0.1 as well?
I am currently on 6.0.1. The other thing to check would be the usb options in the notification area when you plug it in, if that shows up.
That's what I'm hoping for as well but nothing shows up, very odd.
Have you tried using your OTG cable on another device? Or using another peripheral? Do you plug in your device to charge it? I'm just trying to think of all the possible things that could be awry.
Well so it worked fine on a Moto G and X and I had only tried a keyboard and a mouse. I've now tried a USB stick and it suddenly works on my Galaxy S6 as well. Keyboard and mouse now suddenly work as wel... I'm starting to think it must have been a loose connection due to my phone case or something cus I can not think of any other explanation as to why it suddenly started working. Regardless, thanks for your help!
