I have a 2.2.1 (rooted) Mesmerize and I can't get it to recognize anything plugged into the Samsung Micro USB to USB Adapter I just bought.
The phone is set to "Mass Storage" for USB and I've tried both USB Debugging on and off.
I can't get it to recognize any of 5 thumb drives that I've tried connecting to it. So either it's a bad cable, or something else in the phone is preventing the connection. Help, please!
EDIT: I'm possibly naive in assuming that this (reading a USB thumb drive from the phone) will work at all, but since they (Samsung) sell the cable and tout it as being capable of it, I must just be missing something such as a setting or the necessary version of Android or a wonderful hack from this group.

Here's a cross post from the Mesmerize thread where I'm not having any luck:

Moving to Q&A
What you are asking for is a USB host function on your phone. As far as I know there is none for the Mesmerize or android. The cable is to connect your device with a pc or other that does have usb host drivers.
there are probably other, better ways of getting extended storage. what exactly are your trying to accomplish?
I just figured it would be cool to read off a thumb drive (or usb card reader set up as a thumb drive with an sd card or micro sd card attached) from my phone. For instance, if I'm out somewhere and I take a picture with my camera and I immediately want to get that picture from the camera to the phone (without using a pc as a bridge)... I could just remove the sd card from the camera, plug it into my card reader, plug my card reader into the micro usb to usb adapter and then plug that into the phone. Whereupon the phone would recognize a thumb drive is attached and let me navigate it the way I navigate the internal micro sd card.
yeah I don't think usb hosting was available until 3.1
I don't even know how easy it is with newer devices.
What about with a custom mod/ROM?
mad towner,
i would like to know how did u root ur phone. i have a tab with same os as yours. but i find it very difficult to root.
thanks in advance.
Hi!
I've rooted my Ace2 and tried to get USB OTG to work in order to connect external storage and to use DSLR Dashboard. USB Host diagnostics gives the following information (s. attachment). Neither external storage nor DSLR dashboard works. Is there a way to activate USB-OTG by editing config files? In that post I've read that the /etc/volt.fstab hat some lines commented out related to USB OTG.
EDIT: Replaced wrong screenshots
Any ideas? Wrong forum? Any suggestions?
You are using a specifically OTG cable to connect?
The cable must ground the ID pin on the USB connector of your ACE 2.
Many devices will work correctly (and automatically) when they receive the interrupt from the grounding.
See if you can get a USB keyboard to work first.
I used this (Amazon de Product B0068CEUAA) USB OTG cable.
I am not sure but in another post on xda I read that one need a new kernel where usb otg support is compiled in. I checked dmesg while connecting an usb drive, nothing happens there.
Has anyone with any USB OTG cable got this function to work on the Ace 2 (GT-I8160)?
Hey everyone, I'm currently running the latest stable version of CM10. My phone also has a microSD card inserted in it.
My question is about connecting to the computer via USB port. Normally, with stock, when you connect to a computer you have to allow it to connect and disconnect it before you remove it from the computer. I think it has to do with USB debugging (which I have off)? However, when I use CM10, I get no prompt whatsoever.
Is it safe to just put it in and pull it out (that's what she said)?
If I enable USB debugging will I get this prompt again? Is it even possible to get this prompt again?
I've tried looking all over for an answer, but it's kind of difficult to word in a search. I've been just pulling the plug, and I'd really hate to damage my precious SR!
Thanks, y'all

When you plug the usb in pull down the menu on your phone and it'll give you the option to connect usb. Just Swype down from the top of your screen.

I think CM10 and 10.1 have USB OTG which means you don't have to allow/disallow it anything. Just pull the usb cord and that's it.

Excellent, thanks!
I don't have this device but when you install JB, it use MTP mode as default, which is a Microsoft transfer standard. MTP mode allow you to use the phone storage space (and Sdcard) while transferring at the sametime, for example, if you have apps installed or files on your Sdcard they will still be accessible while plugged in. You can unplug it anytime and there are less chances of files corruption. However MTP also have its limitation such as being retarded.
The other mode is USB MSC (aka UMS aka usb mass storage) which we're familiar with. You could pull the chord with this mode too since its really how USB transferring is designed, but it's better to safe remove first to prevent corruption.
USB debugging is something different which allow ADB access, which I recommend turning off when not in use for security. It should work with both UMS and MTP mode.
USB OTG means on the go, which allow plugging in USB peripherals such as flash drives and is only available for phones that have both the hardware and kernel that support it. Sometimes you also need additional mounting software such as Stick Mount.
Some phones allow you to switch between UMS and MTP mode. Most newer ones running JB only have MTP mode and donot allow UMS mode at all, such as Nexus devices and Galaxy SIII. Also if the device only work with MTP you will not be able to mount USB storage to your PC while in CWM.

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.
I think I'm doing something wrong, the Pixel 2 only works with certain cables, or something else (port defect, OS defect, special drivers needed, etc.). I wanted to transfer some files from my PC (Windows 10) to my phone. I have a USB 2.0 to type-C cable that I plugged in. The phone came up in Windows but the contents of the window were blank. I could not access any contents or view anything on the phone. In Settings under USB I saw it said "charging" so I selected "transfer files" and it disconnected from Windows and reconnected only to go right back to charging. I have locked/unlocked, restarted the phone, tried different USB ports, and nothing works. The only function that works is "charging." When I use the supplied type-C to type-C that came with the phone I can get it to work only if I plug into the computer, then the phone, lock the phone, and then unlock it using my PIN (not fingerprint). I ordered a USB 3.0 to type-C cable to see if that works. Is there something I'm missing on why the phone won't connect with a USB-A to USB type-C cable...except to charge? Drivers or something else?
Also...I've reset the phone once (that didn't work either)...and even tried enabling USB debugging.
Please help. Thanks in advance.
Well...I think I figured it out with more troubleshooting. Apparently, you can't connect this phone to a computer via a USB hub. I was able to get it to work by plugging directly into my computer. I tried it on two different powered USB 3.0 hubs and it didn't work. Not sure why or if there is a way around it for convenience.
