Hi all,
Apologies if this has been answered elsewhere but I have looked and cant find anything.
My One S is Jelly Bean 4.0.1 (un-rooted)
The problem I have is basically this.
I have a Micro-B Usb Otg On The Go Cable and Integral MicroSD USB Card Reader with a 32gb Micro SD.
When I first put all this together and plugged into the USB slot of the phone everything was fine, the little red light on the Integral MicroSD USB Card Reader was lit up. The message of Unable To Charge Device was coming up but the phone was also mounting the storage for reading via Astro File Manager no problem, so I was able to play MP3's and 4's and so on. But then it literally just stopped reading the Micro SD card and the Micro USB Card Reader is not lighting up at all.
Any help will be greatly appreciated as I am at a lost as to why it would be working perfectly one second and then not another.
Thanks you.
Follow up.
Been doing a little bit more looking into this and it looks like it has to do with USB hosting. Is there any reason my phone would just stop hosting a OTG USB Flash Drive? As i mentioned before it work fine for a while and literally just stopped recognizing that there was any Mini Sd attached.

You seem to be stock so not sure what's up with that but could try factory reset in the bootloader has long has you haven't changed recovery but backup what's on the SD Card because that will get wiped too.

Thanks Darknites,
I have reset hard from the settings menu, does it make a difference if i reset from bootloader? I have downloaded USB Host Controller and look at what results I get from running that and I get the SC3 USB Host Driver Not Found which I believe is something to do with the chip set which doesnt apply to my phone but I also get the message of USB Root Hub Present but I also get Not Present sometimes when re-running and the same with USB Host Mode is Active and then sometimes Not Active after re-running the Host Controller App.
I did read somewhere that its possible that certain chip/chips might have been damaged/fried by an extended use of USB Hosting to a flash drive, is this correct?
Thanks again for the reply.

I havnt heard of that in YEARS, and even that was in most cases a false rumor. I have never encountered a chip dying by being used properly.
If you short-circut the cables or something - then yeah, thats a different story.

Ya in bootloader everything gets wiped even sd.
I did cross my mind re the cable because the drives are fine in my PC, I know they are powered there though. I might try another OTG cable, there cheap as. Its just strange that one minute the Micro SD drive was working perfectly and then kaput.

I bought a small micro - usb female adapter. When I plug it in, no matter what device i use it seems as those the xoom is not sending any power through it.
Ive tried
Camera
Charge Phone
usb mouse
usb wireless mouse
nothing is getting power.
Is there something i need to enable or do? Or has anyone esle has this issue? I am on 3.1....
You can not use a simple micro usb adapter cable, it has to be an OTG USB Host cable like the official Motorola camera connection kit that is now available. This is a bit expensive but readily available at your local Best Buy.
Take a look at some of the many posts on OTG cables and you can find info on cheaper cables that have been verified to work or on how to make your own.
you need a USB Host cable. Not just a regular sync cable. You can google for one or search the threads here where others have linked to confirmed working cables.
dang, thanks guys
I ordered one from ebay! hope it works
I have a question that applies here, I am on stock 3.1 Xoom WiFi/3G and just got my OTG cable, plug it in usb drive blinks like its working but where is it located on the Xoom? I've been looking around for it with Astro and File Explorer and I'm unable to find it... could someone tell me the path?

i believe stock 3.1 only supports MTP, hence no USB mass storage.
http://en.wikipedia.org/wiki/Media_Transfer_Protocol
I've heard many conflicting stories, I would like some sort of confirmation rather then speculation about what will/will not work with the Moto Xoom (Stock 3.1) Wifi/3g and an OTG cable because I've seen posts saying yes and no to USB, portable HD's etc etc. Can anyone even provide me with some informative links? Everything I've searched for has been less than informative.
So, stock 3.1 Xoom is an MTP device, that is true.
However, with latest series of Tiamat custom kernels by Bigrushdog (see Android Development section) the usbOTG has been enabled. If you have already rooted and installed the proper bootloader/Tiamat kernel, then in File Expert you will find the usbOTG folder on the root directory, same level as internal sdcard and data folders. If you go up a step in sdcard, you should see your external sdcard. Is this clear?
I have rooted, using the Tiamat 1.6, I have access to the sdcard now but I am still unable to access my usb drive (thumb drive). I have an OTG usb cable and when I go into the /OTGusb its empty. The drive blinks as if its initializing but then nothing.
On a side note, I have looked through both OTGusb folders, restarted the Xoom with the OTG and usb plugged in as suggested in another post and nothing I've tried has worked in locating the usb drive.

I've found that there are two factors which may be in play here...
1. When I connect a flash drive it takes a bit of time for the directory structure to parse... It does show up in the OTGusb directory.
2. I've found that anything larger than 8GB (I've seen it stated in the forums as well) does not work (of if it does it takes forever and a day to become available)
Hope it helps...
I have same problem here. whenever I try to connect the USB with Motorola connector, it doesn't appear anything in otgusb
I'm not sure I am going to get what I want at this time with the OTG cable. My goal is to be able to use the OTG cable to connect a USB thumb drive to so I can carry additional movies, documents, etc without completely consuming the main Xoom storage.
Can the OTGusb cable support this? Do I need to wait for yet another update?
TIA
So i installed CM 7.1 tonight and when i plug my phone into the computer using my usb cable it detects my phone, charges it and allows me to mount for usb storage.
when i mount for usb storage i do not see the sd card under removable hard drives. im new to all of this rooting and this is my first time rooting and installing a custom rom so any help is greatly appreciated.
thanks!
Search on forums. Theres a thread about that. I think you need a proper driver for you pc, in order to communicate with your phone.
Sent from my LG-P999
i have searched the forums, most of the issues are saying its not mounting and what not. i do have the LGdriver downloaded otherwise i would not have been able to put the necessary files onto my sd card. the problem started after i rooted my phone. my computer recognizes the phone when i plug it in but once i got into USB mass storage mode it doesnt show up in my removable hard drives..
sorry if sounds confusing, im having a hard time describing what exactly is wrong with it.
when i click turn on usb storage it'll say USB storage is on and the green android guy will turn orange and all the apps that are on my SD card are no longer in the app menu. but i have no way of copying files over to my sd card.
Go to Settings>Applications>Development>USB Debugging and turn that on, then plug in you USB as usual.
Hope it works
it worked! thanks!
at least you guys arent having the annoying problem im having.........every other day my phone says i have a blank sd card and when i put it in the pc it tells me it is damaged. It only does it when i mount it to usb. I think it is because the phone gets a little hot sometimes. Quite annoying
Here's a cross post from the Mesmerize thread where I'm not having any luck:
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.
Please use the Q&A Forum for questions Thanks
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,
Wondering if anyone has problems connecting a smartphone ? When trying to connect to the usb port of the dock on TF700T my Sony Xperia S is not recognized, no message appears that "mass storage device" or "usb device is being prepared".
kind regards,
What Android version is your phone running?
Once my phone was in USB connect mode, I had to go to the transformer settings > storage and then scroll down to the bottom and select the option to mount the mass storage device.

Doesn't work for me, there is no available device to mount, there is no sign it is even connected in usb mode,my phone simply isn't recognized for some reason.

I never saw any pop-ups or notifications in the status bar either. My first thought was that the device didn't know my phone was attached. I had to do some google-fu before I found the suggestion that, even though you don't see any notifications, to look at the storage settings anyway. Very strange that nothing is showing up for you. This might seem odd, but would you happen to have a USB hub you could run through? Try connecting the phone to the hub in storage mode, then connecting the hub to the transformer.
I can confirm that I did not have any notification either. My phone however detect the USB plug and I could activate USB mass storage on its side.
Then i needed to manually mount the external storage in settings. This done, I have access to the external SD card of the phone but not to the internal one.

Besides the fact i can't seem to connect it, that would be a problem also, because with the Sony Xperia S there is no SD card slot available for external memory, only 32GB of internal memory.
kind regards,
Not quite satisfied by my first test, I have made it again. With the two cards in the phone I can only access the external one. So I retreave the external card out of the phone and renew the test. this time, I can access the internal card.
So it seems that i can only see one card at a time, even if I need to mount it manually.
In any case if you have only one card, you should be able to access it.
My s22 ultra suddenly does not work on dex. Theres no way to access the sd via a pc either.
I was using this exact setup and it worked fabulously.
As far as i know i went to bed one night and it didnt work the next time i went to use dex.
Reboot phone and pc? Is the phone recognised when connected? Try another cable, does it work on a different pc. Do other USB devices connect ok etc etc
i have rebooted both phone and pc. Same cable as when it did work infact the samsung original that came with the s22. My s9+ does not connect. Both phones DO charge via usb c.
I have infact reinstalled my pc and resest my phone to factory trying to fix this.
Still to no avail.
Does it connect to another pc? Usb pc hub might have failed
its a brand new laptop and it does power the phones. and it all did work fine. i can even power my usb c vape through the same port
there is not an alternative machine to test on
actually i just thaught of this, the last night i was using it i had the standard popup on my phone asking to allow dex to run. An ok responce and cancel or not now responce, i dont remember exactly.
Could this have done something if i hit cancel
also could there be something in the pc bios i may have not realized could effect this. Since i was on the same night trying to boot to a usb linux pendrive
When you connect your phone can you access its files on your pc? Is it recognised as drive
Ok so ive even reset the bios to system defaults and tried a regular usb to usb-c and still nothing

could it have anything to do with the phone usb connection settings. When you plug in a usb otg it normally would give an option for transfer or charge etc on the phones pull down menu and all its doing is saying fast charging
Try phone on another pc
Absolutely everything else works through usb mate.
What else can you access via USB. Drives, devices?
well i can access the standard usb port with an sd card reader. read write and even installed windows off it. So this usb to usb c should work fine.
If it were just the usb c hub blown this would not be the case.

im currently trying to see if i can run a lubuntu through usb bootable key and try to access the usb c ports from that.
I have been reading about my laptop and apparently it has a reputation of usb issues. lenovo x1 yoga gen 2 on win 10
Solved. During a bios update it appears the bios setting for thunderbolt usb-c was changed to disabled. As soon as i discovered this and rebooted it worked so if anyone is having issues with this they may want to check there bios settings.
4 days of struggling over. Dang its nice to beat a computer once in a while.

Do you have Link to Windows enabled on your phone? If so, turn it off and try running DeX.
