[A] USB recognition issue when plugging in ASUS ME172V MemoPad - Android Q&A, Help & Troubleshooting

I have an ASUS MemoPad ME172V that I have rooted successfully.
Afterwards I had and issue with Windows 7 recognizing the tablet when plugged in and allowing access to the microSD/onboard memory.
So I installed the USB drivers for it - downloaded from ASUS.
The device was showing up on my Devices/Printer window as "Unknown" - but had an icon with ME172V under it.
So now what? I need access to the device and the microSD card!
Well, I solved the issue and I wanted to share since I did not find a thread on it.
You need to set the tablet a Media Device to allow file transfer.
To do this - do the following:
- Go to Settings, then Storage.
- In the upper right corner - click the "three square" icon
- This opens "USB Computer Connection" - click it
- Now the window should say - Connect As - select Media Device(MTP)
Hope this helps!

[Q] Can't Access Tablet through my computer after Vegan-Tab 5.1.1

I loaded Vegan-tab 5.1.1 and everything is working great, except that i can't see my tablet as an external device anymore while connected by usb to my computer. I do see the sdcard & sdcard2 files from the ifilemanager.
Is there a way to fix this?
I noticed something similar and it turned out to be me. I was expecting the "USB connected" message when I plugged it in. However, when I looked at the top bar, there it said "USB". I pulled down the bar, clicked on USB CONNECTED and I was back in business.
Possible for you as well? Something to check...
Me too
I'm having a similar problem with Vegan 5.1. The tab is connecting and I'll go to select "Turn on File Sharing" or whatever the option is and everything will appear hunkydory. However, if I attempt to transfer a file it will hang up for a while (on the PC side) and then eventually the connection will be broken. If I look, there is a file of the right size on the internal sd, but I'm not willing to fool around with them in case they're corrupted.
Somebody please help! I've had a good search and can't find any recent posts on this topic.
My trouble shooting advice :
A) 5.1.1 has a pull down menu that you have to "active USB"
B) I installed android USB drivers on my PC just in-case so i wouldn't have connection issues.
C)May need a "powered" USB port like Portable HDD .. example: (MAC keyboard USB port isn't powered).
Vegan by default after install leaves system in USB debugging mode. Go into setup/ applications/development and turn it off.

[Q] OK, I have a real mess - Please Help!

I did an NVflash after struggling to load VEGaN 7 for a couple days figuring it was the partition issue that I have read about. Flash went off without a hitch - or so I thought.
I went to flash VEGaN 7 again, but my computer would not recognize connection via USB. Attempted to login to clockwork mod but instead I get message - "booting recovery image".
Thinking a factory reset might somehow free up my USB connection I did a factory reset - now I'm stuck in a bootloop.
So, to review--
I can't connect to PC via USB, Access CWM, or get past the bootloop.
BTW - I noticed while looking for options to connect to USB that it appeared my Internal and external SD cards switched locations after the NV flash. External, although not accessible was 12.9 gig and my internal showed slightly less than 1 gig.
Anyway, is there any hope for my G tab - I have never been so frustrated over such a simple process in my entire life.
sorry looked for a way to move this post to the correct location...

When you NVFlashed, did you use the version with or without CWM. If you did the version without CWM then that would explain no CWM.
When you say you can't connect to PC are you talking about APX mode (NVflash)?
Go here http://viewsonic-gtablet-for-dummies.webs.com/ and follow the instructions for CODE RED step by step. Make sure download everything via the links on the dummies site to make sure you get the right stuff.

No I used the version with CWM, which is why I was suprised to see the "booting recovery image" and then it just continued to boot. I tried both APX via USB and a typical USB connection after loading --where PC gave error "device not identified".

So, just to verify, you hold Vol(-) and press/hold Power, 3 birds appear & screen goes black...that is APX mode. Connect usb cable to PC & what does the PC say?
USB device not recognized -
Still having that problem with USB device not recognized.
However, I have gone to ...for dummies site and reflashed device using the "flash USB driver" to temorarily gain access with USB connection. With NVFlash I Am back to having clockworkMod and working GTab with original software 1.1
Again going to flash rom - but Upon connecting USB i get the message "USB device not recognized" - I have attmpted to mount USB through CWM, but still getting that same error.

If your tab boots, you don't have to use CWM/mount & storage to transfer your rom to the internal sd. Put your external in your PC, copy the rom to it, move back to the tab & copy to your internal. There are also other ways to transfer it but we can talk about that later if you like.
If that works you can still flash your rom & then we can work on getting the usb up.
So, the usb not recognized is when you try to connect after your tab is either all booted up or in CWM mount & storage (and not when you are in APX mode doing NVFlash)?
If you look in device manager what does it show?
Try connecting your tab to a differet PC & see it detects it correctly?
If it works on another PC, you may want to tryto use USBDview http://www.nirsoft.net/utils/usb_devices_view.html to look at the USB dvices that are connected or have been connected to your PC. You can find the gTab devices in the list & then use it's command line options (see instructions included with it) to remove(uninstall) them from the PC. Then you can reconnect to see if it will detect & install the driver correctly.
Can't use external load on pc to transfer rom. No card access.
USB did work in apx mode following instructions in code red. I thought of usin another pc and duplicated the failed results there.
Device manager showed yellow exclamation mark and would'n't install any driver I pointed it to (both computers) Unknown USB device.
Btw I want to thank you for trying to help me out on this. You people who lend your knowledge are commendable.

OK, try this. We are going to use Mobisynapse to wirelessly transfer files to & from your PC to the tab.
Download mobisynapse from my dropbox http://dl.dropbox.com/u/36150173/Mobisynapse.exe & install on your PC.
From your gTab, download Mobisynapse system tool from my dropbox to your tab & install http://dl.dropbox.com/u/36150173/com.mobisystems.office_registered-1.apk.
Start the app on the tab, click More & select Connect to PC to switch it to ON.
Start the Mobisynapse on your PC, it shoud see your tab, once it sees it click connect.
From there, go to the Files icon & you should see an Explorer type screen. PC on the left, tablet on the right. You can transfer files in either direction. Transfer your Rom files or whatever you want.
Let me know when you have downloaded the apps from my dropbox so I can remove them.

I downloaded them and installed, on tab it shows up as officesuite. When I run it "more" is not an option. On pc it simply says (can not connect to android device) under "choose devices". I did turn on USB debugging on tab.

It's easier that way, that way you can easily differntiate it from other files/folders. If you create the folder, then put the zipped rom inside the folder.
I turned connect to pc on. Running mobisynapse on pc it sees the tab just fine. I click connect and it pulls up info about tab, BUT when I go to files tab --- right side of screen is greyed out. It won't transfer files.

Third icon from the left...looks like a little file cabinet.
lol, yeah 3rd from left...
It seems to connect just fine, but under the file tab I can only see files from the PC on the left - the right side doesn't show any files and all buttons are greyed out. Again, under the home tab I have access to the GTab just fine. I can see apps, contacts, etc. but under file tab - no files on right side and buttons are not accessable.
So do you see the left (PC side)? Is the right side populated at all & what is in the drop down folder box (should be /sdcard)!

Unable to install drivers needed for rooting

So, apparently I need to install a few drivers for rooting this. The one set of instructions I got is to enable USB debugging and then find a device called "ASUS Android Composite ADB Interface" with an exclamation mark in Windows Device Manager. Trouble is no such device exists. I plugged in the TFP with USB debugging!
What to do?
What version of Windows are you running? Do you have Asus sync? If so can you see the Prime as a storage device when connected via USB?
It can show up as various items depending on which driver version and the actual text string in the .inf file. Have you tried having device manager already open and watch it to see what ( if anything) changes as you connect the prime? It can appear as a device under the "android phone" heading or as other things... plug it in whilst watching device manager update, let us know what is added to the list and maybe we can help...

ICS and USB debug/Mass storage

With the new ICS firmware (and I don't know if its all ICS) you need to turn off debug in order to use Mass Storage.
Is there any application or other way around this? It gets a little annoying to always have to do this.
Titanium backup needs debugging on for some of my apps and if not using mass storage mode the phone connects via MTP mode which is very slow
I would willingly pay for an app/widget that does the following
Once pressed turns off debug and asks you to plug in USB for mass storage.
Prior to disconnecting the USB cable you select to disconnect which then un-mounts the storage and then turns back on debug
figure should be easy to make for some dev out there
Anyone have an idea on this?
Guess no one out there has an idea
Hmm, for me the only difference running ICS and checking or unchecking dev option/USB debugging is whether or not I can manually unmount the phone in Windows, it always connects as a media device and I have no otion to turn that off.
Mediamonkey takes forever when my phone is connected as MTP (say 15 minutes to build the sync list?), and the only real option to use it to send fresh music to my phone WAS connecting it as mass storage (15 SECONDS for the sync list).
So I would really really appreciate any hints on how to get my S2 to connect as mass storage. It's the official ROM rooted using Chainfires respective kernel.

Or at least an app that selects and deselects the option automatically as I mention above.
Sure a dev somewhere can make lots of money for an app like this

Thanks for the info but I already knew this.Also you didnt need all these steps in gingerbread and previous software versions.
Also for people using USB debug this must be turned off before being able o do all of the above.
Im just saying an app can be made that does all of this with one click
Well, get onboard here, test and say if it works.
I have USB Debugging always on and I am currently running LP7 version of ICS.
When I plug in the the phone I get the Media Device (MTP) coming up on the phone - which is ticked.
In Windows Explorer (Windows XP) just below Control Panel (in the folders window) is a +GT-I9100. Clicking on the + I see a subfolder +Phone The items in this folder are the Internal SD of the phone.
From this I just drag and drop. I haven't noticed any difference in speed between this new way and the old method in Gingerbread.

Try transferring a large file you will see the difference between transfer speeds in MTP mode and mass storage.
Also with MTP you can only do one thing at a time. For example let's say you are transferring files. While doing that you want to erase something else. It will wait for the original transfer to finish prior to starting

But will this work even with debug on?
Yes. As mentioned in the linked post:
- connect cable
- classic "usb connected" notification appears in notification bar with option to do usb mount
- adb available.
Doesn't like my Mac either
When connecting my galaxy s2, I get the attached error.

MTP wont even work properly on my Windows 7 machine. It refuses to update the explorer process as long as the phone is plugged in. So navigating the phone means a lot of plugging and unplugging to get anything out of it.
Changing to UMS means my 2 devices (Internal SD and External SD) are visisble right away, but sadly are not displayed with any storage bars underneath . As a result I can't access them anyway and the second my phone goes to standby it stops the "process".
So any help or hints how to get my damned phone to actually work and show the storage bars underneath is most welcomed.

Will reward if tested and solved - 2nd Kindle with Same Odd USB Issue

I just received another KFHDX 7" to replace my old one.
Here's the situation:
- 1st HDX couldn't connect to Home PCs. One running Windows 8.1, and the other running Linux / Ubuntu.
- Talked with Amazon support and did all the listed troubleshooting techniques they told me to follow (most likely online "Google-ing" with me on the phone).
- My conclusion I told them, from what I think the issue can be, is that either there is a physical issue with the connectivity inside the KFHDX, or that a file corrupted when the battery died that is used to have the computer communicate with the PC.
- Amazon support gave up and sent me a replacement KFHDX 7" with firmware 13.3.1.0 on it. "Woo-Hoo!"
- 2nd KFHDX rooted and ready to go.
- Connected to Home PC to transfer files. Worked just fine.
- Connected to Work PC to transfer files. Worked just fine.
- Go back home to transfer files using Home PC.. USB issue. This time the KFHDX is giving me a different error message: "USB Compatibility: Some computers require a free file transfer utility to copy files between the computer and your Kindle. If you need this utility, please open your computer's browser and navigate to kindle.com/support/downloads. Your computer's USB port is a low output power source that will slowly charge your Kindle while asleep and may not charge while in use."
- Mind you I tried using both the front USB port on my Home PC (Win 8.1), back USB port on my Home PC (Win8.1), same USB cable, and different USB cables.
- Went back to my Work PC and it gave the same error, then.. some how it worked!
- Decided "Maybe uninstall the Kindle from the Device Manger utility", which I did, and left back home.
- Connect to Home PC. USB error message on KFHDX 7" device.
Any thoughts? Opinions? Also I really feel that a file was corrupted. If so I installed SafeStrap and Recovered my KFHDX stock ROM. Still had the same USB connection error as before.
Any files to download to the KFHDX to replace an old one? Or can I edit it myself using ES File Explorer?
If solved, tested, and my device can reconnect, I promise to give lunch/beer money for the one that fixes the issue. Thank you.
If it is beyond fixing then I will return it and wait until Google announces their next Nexus tablet in July 2014. Maybe as a "hassle-free" holiday college present. And hopefully similar or better hardware when compared to what the KFHDX has.
I'll also try to talk to my network admin that might have the Work PC with some kind of software where it makes this connectivity issue happen. I can download files off a cloud but USB is much faster and convenient.
.
.
Issue was solved.
My steps:
- Open Device Manager on PC
- Look to see if the Kindle Fire HDX is listed as Kindle, as if it is a device choice (Could be in Portable Device, if so expand it and you should see Kindle listed underneath).
- Disconnect KFHDX from PC. The device listed as Kindle should disappear.
- On KFHDX go to Settings / Device / Enable ADB and turn that off.
- Reconnect KFHDX. If I remember correctly the PC's Device Manager utility will label it as an Android Phone. (If not then sorry I can't help there. My first KFHDX 7" was giving me a different issue that I couldn't resolve. Amazon replaced mine after I tried all the troubleshooting techniques they gave me. Therefore this helps for those having this similar situation.)
- Now update drivers on the "Android Phone"
- Then out of no where my device could communicate with the PC again.
Hope this helps someone if you were having the same issue.
Now to reward myself to a lunch and drink
