[Q] TF300t USB stick and file issue. - Transformer TF300T Q&A, Help & Troubleshooting

My problem is a fairly unique one in that its happening only on the USB stick that is used for music storage on my car deck. The symptoms are as follows and ive tried many things (see bellow) so i put it out there:
When copying .mp3 files to my USB flash drive to load them onto my car the car deck no longer recognizes them at all. They are not present on the list at all. Once i successfully got the file to be seen but it wasnt recognized and my deck threw a hissy fit.
With my usage of tablet a full sized USB is a must. If the tablet doesnt have it then its useless for me as i do alot of file transfers for clients and personal. My tabet previous to this was a Acer Iconia A200 with built in USB and android 4.1 and no such problems existed. Windows can see and read the files I put on any USB disk so its not a problem for workplace, its only happening with the car stereo.
Has android 4.2 changed something in the file transfer protocols for USB?
Attempts to fix include; buying a usb stick that is only a microSD adapter and using MicroSD to transfer files and SD as well. Various file viewing apps including all the top ones in the Market and the Asus factory app. Forum searching, hoever, due to the problem being only with my car stereo I found nothing. When using windows I can see the files so I copy them off and back onto the flash drive then the car dec can see and play the files.
Please help if you can.

[Q] File transfer from PC to G Tablet?

I'm trying to transfer files from my PC to my tablet, but the PC doesn't recognize the tablet - it wants me to format it. Same thing when I try to transfer the files from my mp3 player, the content of the player should be listed in the usbdisk folder, correct?
This is driving me NUTS, I'd appreciate some help. Oh, and tablet is rooted - VEGAn.
Thanks!

Do you have ADB working
OK, please bear with me, I'm noobish - but what is ADB?

Rooting this Gtab is somewhat of a different process fyi
You could always use dropbox, Google it
It works fine for me, with no ADB installed (Vegan 5). Plugging the Gtab straight into the PC and turning on USB storage should recognize it as a USB storage device, like any other USB key.
OP, what operating system are you using? Have you tried a different USB cable? A different USB port on the PC? Perhaps a different PC (if one is available)?

Hi,
For the PC, are you connecting from your regular size USB connector on the PC to the *mini-USB* port on the side of the Gtab (not the full-size USB under the cover on the side of the Gtab)?
The mini-USB connector is the one you need to use to connect to your PC.
The full-size USB under the cover is a "host" USB, i.e., you can connect a flash USB drive or USB hard drive to that, and then assuming it's formatted FAT32 with only ONE partition, you should be able to see it on the Gtab under /usbdisk.

- My PC OS is Windows XP
- I am using the small port on the tablet, not the USB port under the cover, to connect to the PC
- I don't have a different cable/PC to try it with
- FYI - it WAS initially working when I tried to transfer files from my mp3 player to the tablet, the transfer was interrupted when the cord came loose from the tablet, and now it's no-go for both the PC or mp3 player file transfer process
- I do have a permanent folder usbdisk on the tablet, even when there's nothing plugged into the usb ports
Thanks for all the questions and suggestions, I'm glad there's people more savvy than I am with this, willing to help!

The small port (like a camera cord) should work. The cable has a USB end on the PC side. It should be recognized on the PC as an external drive. No need to install ADB unless you want to try that too.
One idea is try plugging the USB cable into different ports on the PC end.
If you have wireless and can share network drives on your PC, try File Expert. Its free and can be found in the market. With it I can connect to my PCs drives and copy to SD or USB in my GTab right on it. Granted, it took quite some time to copy a 1GB movie to SD2 (10 min), but it worked. I had to prevent my device from sleeping though or the transfer failed. Worked well though. I'm on TnT lite.

Hi,
I seem to recall that roebert (I think) had a problem w the miniusb connector being loose or broken. Have you looked at the connector in detail? Maybe the solder connection broke and it 'jiggles'? If so, probably need to get it repaired.
Jim
Well, I know it's not the cable, because I used it to transfer files from PC to mp3 player without any problems.
My PC shows the tablet (drive letter E assigned to it when plugged in), but I can't access the tablet - it's like the PC recognizes something is plugged in, but it doesn't recognize it as having content or something.
On top of that, I kept getting the android.process.acore error, so I did a datawipe and had to re-download all my apps again, to add to the aggrevation.
I will look at the different solutions suggested and if they're not requiring too much advanced knowledge, I will attempt them.
Thanks again for the help & suggestions so far, hopefully I will somehow stumble onto a fix that works!
So, I figured it out. Really simple - if you know how.
The VEGAn root is what did me in - when you plug in the cable, it doesn't give you the option to turn on the USB Mass Storage, which you need when you want to transfer files from PC to tablet. The unrooted device was a bit more user friendly by walking you through it when the cable was plugged in.
I figured out that if you tap and drag down on the USB icon on the top of the screen you can actually access the options - it's not just a status icon!
Hopefully this'll help out someone else who's rooting their tablet following instructions blindly without really knowing what's what!
Thank you again for all the suggestions, I really appreciate all the responses!
Astro SMB Module
If you are working on a home/private network and the file is on a shared network drive, you can map it in using Astro and the SMB Module for Astro ("Astro SMB" returns both in the market provided you have the market fix) and browse shared network drives just like you would on your laptop or PC.
Once installed, a network icon appears in Astro (looks like an upside down "T" or an old school windows network icon) and you can map in your network drives pretty easily. I use this with NAS and work files pretty regularly. You may have to enter alternate or domain specific credentials to make it work.
EDIT: Also I believe there are file format limitations, OS limitations, but haven't fully explored that.

[Q] I need an OTB tutorial and answers to some questions.

I have an OTB cable camera connection kit and I purchased a 4 port USB powered HUB and am also using a thumbdrive. I use Root Explorer as my primary folder organizer/file management.
What I did was load up Music Junk and pointed it to my usbOTG directory and into a Music folder. When I download a song it goes directly to my thumbdrive so that I don't have to keep the music on my Xoom, or so I thought. When I disconnected the OTG cable and opened up the Music app the music was in there and was able to be played. Is it stored twice on the Xoom (once on the stick and once on the device)?
I noticed that sometimes I have to refresh a lot in Root Explorer or unplug the thumbdrive from the hub to be able to see any files on it. Is that normal? Is there a correct way to unmount the thumbdrive so I don't corrupt any information on it. I'm testing this out on a thumbdrive because I plan to use a hard drive in the future with the OTG.
Thanks for looking.
Have you tried it without the hub? I've read that people have problems with hubs because the xoom simply can't output that much power.
The OTG cable works perfectly with the HUB. I loaded some emulator ROM's on a flash drive and connected a USB controller to it perfectly fine. I just don't know how to unmount the drive so I can disconnect it. Does it really matter? I'm under the impression that it does because I know you can corrupt files by just pulling it out of a computer without ejecting first.
It depends on the drive. Some drives protect against that, some don't. Majority of them do though.

[Q] Re: Samsung Galaxy S2 (l9100) Car USB internal mount

Hi all, I've been waiting and searching around seeing if I was able to find any kind of fix or something for some time now but it's beginning to get to me far too much.
My problem is when I had the HTC Aria I used to have the audio stored on my phone and plug it into my car's USB connection and the headunit would search the device and find all audio to play through the headunit which I was then able to use my controls on the steering wheel. After some time I bought the Samsung Galaxy S2 (l9100) and to my excitement received the whopping 16GB internal storage as a bonus, so I filled that. And heres where my problem comes in, I cant seem to make my headunit search the internal storage and play all that music, It will only search the SD card (external).
Now from reading all over the internet I've been led to believe by any posts that relate somewhat to this that it wont be possible for this to work, what frustrates me though is that it is possible. I've rooted and flashed various custom ROM's to my device (VillianROM first, Cyanogenmod Nightlies second and now MIUI yesterday). I have successfully had the headunit read my internal (newer and more songs) upon connection twice that I can recall now, I think the first time was after first connection to the car after the cyanogenmod flash and today when I first connected it again. Which led me to believe that it was working and then was just applying a new theme on my phone while hanging at a friends then was taking another friend home and plugged it in and back to only reading from my SD card (external - old crap music) and can't figure out why it has worked twice if it is not possible.
The reason why I am determined to figure this out is due to 16 GB internal storage and only 1 GB external storage and I wish to use my phone to its full potential.
While I'm at it, I guess I should mention my other problem which adds to my determination to get the USB connection working with my car. The USB connection is a much clearer & louder playback (Higher quality) then the AUX (current alternative) and to be safer while driving by using my steering controls.
But since flashing to Cyanogenmod and MIUI (cannot recall whether I had this problem on VillainROM) I've noticed the volume in headset mode (when I have something plugged into the headphone jack - ie, AUX, etc) and I begin turning up the volume from quietest to loudest it get notably louder each press until halfway or a press before halfway and then does not become any louder, which I also think may be making the audio less clear and loud when connected via AUX to my car.
Thanks in advance to anyone whom contributes.
I am usually stubborn enough to sort problems out myself, but for the first time I am asking for help on a community forum.
Anyone have any idea what I'm talking about?
If you need to know anything else don't hesitate to ask.
CM7 volume is a known issues or least it was last time I checked.
Try turning on/off usb debugging is my best guess.
Done that, today at some point it randomly read my internal storage and right now I'm constantly reconnecting it with no success.
The frustration continues as it is obviously possible but appears to have a mind of its own.
With my little knowledge when it comes to android and their platform, is it possible it could be there mount priority of the storage or the internal having something stored on it such as an app that could be in use by the phone which could be preventing the drive from being read?
what the hell... I have the exact OPPOSITE problem.
With my headunit its been only mounting the internal storage, but most of my music I put them in the external since I got a 32gb card!
Could it be mounting the smaller sized storage first? =P
-EDIT-
Actually it should be easier to do it the way you want it to (i.e mount internal only)
just unmount the sd card via the android settings -> storage -> unmount
and once it is unmounted, connect the usb to the car.
The catch is of course if you wanna use the external again you have to manually mount it via the settings.
more info but no real help
I have seen a very similar problem and I feel like I can reproduce it.
I've got a 2010 Hyundai Tucson - it has a USB/aux port in the dash console and can accept anything that can be mounted as flash media, flash drives, ipods, etc can all play back music using the Nav display to browse and playback files from the device.
The stereo plays back music perfectly through both my wife's old and new phones. An original MyTouch 3g and a MyTouch 4g. She's had no problem mounting and reading the files from her internal storage. She can playback music on her phone, the car even remembers her place and resumes where she stopped a song.
I, on the other hand, cannot easily get the car to playback files from my older or newer phone. I started with the original android, the HTC Dream/TMobile G1 then later upgraded to a Samsung Galaxy S 3g/TMob Vibrant. What's the difference? I've run modded android OS on my phones and my wife has not. I had been running CM5 and later CM6 on the G1/Dream until I retired it. Lately I've been using a MIUI mod, Lithium 360, on the Vibrant.
When I plug in to the USB on the car, the phone gives me the mount prompt and the car begins searching for files. Eventually both fail to make any progress.
I've tried many fixes including turning on/off USB debugging, I've tried wiping Dalvik cache, Wiping regular cache, I believe I even did a factory reset, flash zip, full re-install on a road trip just to see if I could get the car to read my files. What I did discover is that the problem is simply not hardware related. I could boot to recovery and use clockwork to mount USB storage. Files were seen instantly and played back fine. However, this doesn't do me any good as I can't really use the device for anything else (safety first ) and not to mention that there's no way I want to run the phone with the screen on for hours. I know there are simple workarounds here. But carrying an aux/patch cable is an extra hassle, and since my phone can hold enough data for my average means, I often don't remember to bring a flash drive with me everywhere. Besides, the USB cable in the dash does double duty, charging while giving access to files.
To be fair, I've only used CM based mods (according to wikipedia, MIUI is somewhat based on Cyanogen) on my phone and have not tried out any other android software. I don't know if that's a connection or not, but it's the only lead I have right now. There's got to be something different about the USB settings in the OS itself compared to stock Android. Is there an apk file one could flash and test somehow?

This thread is above seems to be describing the same problem. This however appears to be an aftermarket stereo.
[Q] After mounting it *immediately* dismounts
Connecting to a Samsung TV (USB debugging ON and clicked on USB Storage until it turns from green to orange) and then browsing USB (Menu => USB device) it mounts the USB ("Android 11GB" which is presumably the internal SD) and then dismounts within a second and restarts initializing. An ordinary USB stick (single file system) does mount.
Is this because the Galaxy S2 mounts two file systems at a time and the TV cannot handle this. Is there an app which only mounts ONE filesystem on the Galaxy ?

Copy from one USB-device to another with Asus Infinity

Hello,
New to Android and new to this forum. I have my TF700T two weeks now and I'm glad I bought it. My target is to copy the content of my Compact Flash cards (16GB each - from my DSLR) to a portable hard drive. Therefore I tried to connect both a card reader and a portable hard drive via an auto-powered USB-hub to the only usb-connection of my tablet. I even tried with another hub and even with a third hub. The only result was that my tablet only found the first device that was connected (regardless wich one: the CF-card or the HD) with the hub and not both at the same time, so copying from the CF-card to the drive isn't possible in one step. Sure I can copy the CF-card to the internal memory of the tablet and in a second pass move it to the HD, but that is very time-consuming.
Anyone who knows how to connect more then one usb-device at the same time via a powered USB-hub and do a file transfer between them? Your help is greatly appriciated.
You can use wi fi transfer to do it with a file manager, like file expert.

@tbtaf: When on vacation or on a photo trip I only have that portable hd, my tablet and a powered usb hub. I think a Wifi appraoch is not applicable then. Or am I missing something?
Sounds like you need to setup a second mount point for the additional device - don't know if that can actually be done or not, but I do know that some people who could not even connect the first device were able to manually specify the device by mounting it in a terminal window.
I'm not sure 100% on the code, but let me try to find out.
Or you could copy the 16 Gb CF card onto the pad's internal memory (or external MicroSD card), disconnect it, connect the HD and then copy it out again.

He already mentioned, he doesn't want to do this, he wants to copy straight.
For now, it's not possible since the powered hub or non power hub unable to recognize 2 devices at the same time.
CF, now there's nostalgia if anything. I thought those became outdated over 3 years ago... Fact is the CF is hardly compatible with mobile devices these days.
No, you can't copy from an external cardreader directly onto an external HDD through your tablet. It can only read 1 storage device in the USB port. Multiple devices works, but multiple storages doesn't. Some people have had some success with USB Flashdrives/Pendrives instead of HDD's though. You could try that.
You can copy from an SD to HDD easily though, so you could consider using an SD with a CF adapter if your camera has no SD slot. (SD's have the added advantage that the pins can't bent.)

Flash Support for Non-Supported USB OTG Devices

Noobie question here. Is there any way to transfer files to and from directly to flash if the phone you have DOES NOT have USB OTG support? No PC in the mix, just a flash, cable adaptor and phone itself. If so, is it possible to do it without rooting? I've tried the PNY Duo-Link as well, without success (r/w from the laptop, phone does nothing). See I prefer to have the flash as my main datastore, independent of internet transfer and local to the PC, laptop, phone, etc.
Recently purchased a Verizon LG Transpyre, Model Number: VS810PP. The closest solution I've found is WiFi File transfer. However, I want to take the PC out of the equation (don't run M$) for the driver:
http://androidxda.com/download-lg-usb-drivers
Any help would be appreciated, maybe I should have gone the Moto E?
Wifi File Transfer does require not only Mobile Hotspot, but Mobile data too ;( You get an ugly Verizon subscription message with Mobile data even though you want to tranfer from YOUR PC to YOUR flash. Still a lot of hassle to go through though all you want is a non USB OTG phone to flash.
I can use bidirectional transfers via a miniUSB to USB cable on the Transpyre, but the flash isnt there. Had a talk with Sandisk technical support about non USB OTG solutions they may have for file transfers. Basically with OTG (MTP) only Microsoft supported scenarios work to a PC, there are no flash options and to to try Amazon. Bottom-line is, according to them, is if you have a non USB OTG phone, your only option is a SD option.
I just like everything I have on one media i.e. not multiple, SD, CD, flash etc. On top of that I want a bootable media. What would fit the bill would be a male SDmini cable into the phones slot to a female USB adapter for the flash drive, I dont think thats possible. So, some sort of SD adapter for the non USB OTG device is all I can come up with. What do others use for their main bootable datastore media for the phone, PC, Stereo, etc. i.e. the flash drive, SD, SD to USB adapter, DVD, etc.? Or should I just throw the phone and get a USB OTG one
Now the question is bootable SDCard vs USB for all around bootable media for storage to any device. This is what I did, almost there...
Bought a neat little kit from Walmart, Mobile Junkie's 3-in-1 mobile Kit. Basically, I took it's miniSD stuck it in my phone. I can use a miniUSB toUSB cable to the PC and pull the miniSD when I want and slide it into the kit's USB for the PC or booting. Getting close to all the functionality I want other than it's a pain to open up the phone and the bootable USB image I have did not work on the miniSD. The kit also has a regular SD, i.e. miniSD > USB > SD. Not sure if this type of USB/miniSD connection is bootable. But I think all I need to do is create a bootable to the miniSD from the PC.
Any experiences out there between bootable USB's vs SD's?
Conclusion - I'll never buy a phone again without USB OTG support.
