Nexus Media Importer suddenly stopped working after update

I've been showing off the Nexus Media Importer, also using for practical purposes. Got a right-angle OTG cable off Amazon, paid too much, but it worked perfect with the mini-16gb flash drive in it. It also work with a card reader no problem. This was rooted on 4.2 using NMI 3.2.2. No problems, great program.
Then I saw there was an update to NMI 4.0. Installed it and now NONE of my USB devices show up. Always says "No Device. Click Scan to Retry". It used to just pop up automatically when I plugged it in. No longer.
I downloaded USB Device Info.
On the Android side, nothing shows up. On the Linux side, usb1 shows up, looks like the internal USB hub. Oddly enough when I plug my OTG USB cable in, a usb2 also shows up on the linux side. All output is identical except for the device where it said usb1 for the usb1 device, it shows usb2. So there's SOME data communication taking place it seems.
I've rebooted, I've discharged and recharged, I've made sure everything is plugged in tight. I am on 4.2 rooted, and have been since before I even installed NMI 3.2.2. The developer is helping but he seems to be in head-scratching mode right now. So, anyone got ideas? This was no the el-cheapo $0.80 USB OTG cable from Hong Kong, I paid quite a bit to get it from Amazon. That said it probably is the exact same cable but I digress. On the off chance that the cable suddenly died the moment I updated NMI, I've ordered another cable (this time a cheap one, but still the right angle).
Please anyone have help? I need this program to work!
Edit: FWIW I saw that Stickmount got updated to support 4.2. Downloaded and installed it. It also doesn't see my flash drive (which was working fine 2 nights ago). Did my OTG just die or did something screw up my devices? I hate to do a hard reset and go through and reconfigure everything, even with TiBu backups.)

I know this doesn't help you, but FWIW, NMI 4 is working fine now 4.2 for me, so it is definitely something on your end.
Do Windows machines see the usb drives ok?
Do you have another device to test the OTG cable with on your phone like a game pad or a Canon DSLR?
I'd suspect the OTG cable...

Windows sees the drive and the card reader just fine, the two devices that were working. I got a new OTG on the way, even though this was brand new, and no, I I don't have any other device to test it on. Also I tried stickMont since its supposedly 4.2 friendly now and It doesn't see anything either. If the new otg doesn't work guess I'll back everything up and factory reset.
Edit: Actually a factory reset will only clear the data - won't reset the system device files will it? I'll need to get a full 4.2 image and put it on, I guess with Wug's, it's what I used before, then re-root, and restore everything with Titanium Backup. Man I hope it's just the cable. It was only 3 days old tho!

Bad cable! Got a new cable and it's fine.

[Q] USB 3.0 mode not working

When I plug my N3 into a USB 3.0 port on my Windows 7 PC (using the cable that came with the phone), it works fine until I select the phone option to use USB 3.0 mode. At that point, my PC stops recognizing the phone (it disappears from Windows Explorer). Has anyone else had this problem, and does anyone know of a solution?

I had this happen to me earlier- I had to plug it into a different USB port while it was still in USB 3.0 mode. For some reason, sometimes when I switch it, it fails to enumerate the device ID. If you quickly plug it into a different USB 3.0 port, it will work. At least for me. YMMV!

Thanks, but that doesn't work for me.
Here's what happens, in more detail. I plug the phone into a front-panel USB 3.0 port. My PC's Windows Explorer then shows the phone as a Portable Media Player, and the phone says "Connected as a media device. Tap for UDB 3.0 and other options". I tap and then set the checkbox for "Media device (USB 3.0), selecting "Use USB 3.0". At that point, the phone immediately vanishes from Windows Explorer, and the USB "Connected as Media Device" notification also vanishes.
In contrast, when I plug the phone into a rear-panel USB 3.0 port, it never connects at all. It does vibrate briefly to show it knows it was plugged in. But neither the PC nor the phone itself gives any other indication of the connection.

Update: I found a different (Intel) rear USB 3.0 port that works. Apparently it's just finicky about what port to connect to. (All drivers on my PC are up-to-date, though.) I haven't tried any file transfers yet, but the phone notification says "Connected as USB 3.0 Media Device", and the PC Windows Explorer shows the phone and can list its files.

usb not even an option
can anybody help me I don't even have the option for 3.0 and I tried it in 3 pcs with 3.0 master reset and just wondering if its a att issue were the rom mybe was defected thanks just thinking about returning device

This is what happened to me when I plugged in to my front 3.0 port the phone would have the charging icon at the top but would not show connected to USB 3.0 port not pull down menu just showed charging if I put into 2.0 ports USB notification pops right up. So I thought my phone was bad and exchanged it and the same thing happened. So I then turned to the PC I went to my laptop which is a Dell with Intel chipset and i7 plug it in and it was recognized right away pull down menu and 3.0 option showed. So off to the store I went while I was there talked to one of the techs and he told me that ASMedia 3.0 controller on the boards where having problems Intel and AMD now I was on track as I have a AMD Sabertooth 990fx board so I did two thing I picked up a M5A99fx Pro 2.0 and a I/O PCI Express 3.0 card one I got had a different controller than AsMedia on it and got lucky and found one that also had a 20 pin port on the card so I could plug my front port cord to the card and it would give me access to the front ports on my tower. I installed the new mother board and the same thing happened then I put the PCI Express card in and hooked my 20 pin cord up and now I have usb 3.0 on the front but the board's ports still won't work with the phone also I tested other flash drives and USB 3.0 drives and it seems that what the tech said is true with my setup AsMedia is have problems with their controller! The PCI Express card is the Vantec one UGT-PC345 and it has then Renesas USB 3.0 Controller on it. I have since went back to my Sabertooth board and returned the M5A99fx my board is just fine just had to ad the card to get 3.0.

Well in my case the third option just doesn't exist its not grayed out its just not they're so I wonder if its a att deal can some one let me know

I dont know if its related but the issue i have is that when i tap the usb 3.0 option, my phone connects and disconnects over and over about 5 times at whic point it goes back to MTP.
Also, i forgot to add... when it stops all the connecting and disconnecting, i get the message that no software was found. I installed Kies, but its the same thing. This is windows 8.

I have same problem , did you find a solution to this

Only what I mentioned in the update above--it worked to use a different USB 3.0 port on the same PC. The port that didn't work has a different controller, so there may be a driver problem. But I stopped investigating as soon as I found a port that worked.

ok , I have tried both in put and not working

How about a little more info on what your system is. Especially motherboard manufacturer. It seems what ive found in my searching is that most people who are having this issue share one major thing in common and thats the the board manufacturer is ASUS. Im not saying all of them, but most. With that being said im also willing to bet that most problems are on the same USB chip manufacturer. Asmedia chips seem to have the issue. I have 3 towers all with different ASUS boards but all have Asmedia controllers and they all have the same problem. However, if i plug it into my wifes laptop with an intel USB 3 controller, it works perfect.
I have done firmware upgrades, changed BIOS settings, even a reinstall on all 3 systems of the whole OS and in the end i got the same result. The only thing ive been able to get work is if i install ASUS' USB Boost software, my phone will now show its working on 3.0 but only from the rear ports. That being said, if i let it sit at idle for more than about 15-20 minutes, it automatically goes back to USB 2. I dont know if thats intended or if im still having issues.
So, any extra info you can supply might help get a better response. OS, MB manufacturer, controller manufacturer, all of those things will help.

I'm almost 100% certain that BC 1.1 is enabled on your computer. It's extremely common with ASUS boards. It is on other boards as well. Find out how you can disable it from the manufacturer and it will work.

Possibly. But I don't have BC 1.1 enabled on mine, and I have the same problem on my non-Intel USB 3.0 ports (but the Intel ones work).

Thank you. This is the issue I had. I have an Asus motherboard, and I did have Ai Charger+ enabled, that supposedly charges BC 1.1 devices 3x faster.
So for anyone who has AI Suite installed, open it up from the system tray, go to Tool, then Ai Charger+, and make sure it's disabled.

I just re-tried the USB 3.0 port on my PC that previously didn't connect to my N3 in USB 3.0 mode, and it now does. I don't know when or how it got fixed. The hardware is still the same and I haven't manually changed anything on my PC or N3 that would be relevant, so either the PC or the N3 must have received some intervening update that repaired the problem.

An incompatible update for the Texas Instruments XHCI controller was delivered through Microsoft Windows Update. If your computer received this update, use the following steps to roll the controller driver back to the previous version:
Click Start , enter device manager into the search field, and click Device Manager from the results.
In Device Manager, click the plus sign (+) next to Universal Serial Bus Controllers to expand the list.
Right-click Texas Instruments XHCI Controller and select Properties . If Texas Instruments XHCI Controller is not listed, then this step will not fix the problem. Find and use another section on this page.

Thanks, but as just mentioned, my problem already fixed itself. Also, my PC doesn't have the TI XHCI controller. Also, the warning you quote is from more than a year ago, so it is very unlikely to still be applicable.

[Q] Nexus 6 OTG

This is the second time I am posting this as I have posted it once before and did not get even one response from a community known for its extensive knowledge in this field.... VERY frustrating as there was many views and no one offered any help. ANYWAYS,
I have been trying to get my OTG cable for my nexus 6 working for weeks now to no avail... I am rooted unlocked and have tried every app that I have found to help in the mounting process. I use TWRP and am not able to mount through recovery either. I have read that others have gotten an OTG cable to work with the Nexus 6 but like I said, no one has been kind enough to take the time out to help. Because I am out of resources I am going to put my faith in humanity and ask once again.... could someone who knows this process please give me a hand in this? Thank you very much in advance to anyone who would be willing to help.

I dont know if this will help, but here it goes.......
I needed an OTG cable for a device a few years ago. I went to microconnectors.com and searched...I found E07-171-OTG for 9 bucks. I didnt have to do anything more than connect it to my device and was able to wipe my device with no problem. I saw your post this morning and searched for my OTG cable and connected it to my N6 and it worked. Not that I expected anything else, as it is a USB MICRO to USB FEMALE. You can probably find it cheaper elsewhere on the Net, but again I did not have to load any software at all....just plug and play....so to speak. Hope this helps.....

Use Es explorer or chainfires stick Mount and or still work just fine. I use otg everyday without issues.

Thank you both for responding and I really appreciate you taking the time to do so. Unfortunately I believe that there is something more going wrong here than just missing a step. I have tried the CF stick mount and ES explorer. Also I too am using a standard micro USB to female USB connector and its getting no signal even when I look for it using a terminal emulator or adb shell i cant find anything under /dev or /mnt. I really need someone who knows linux better than me on android who can go through a troubleshooting process of elimination with me. Thank you both again for your quick reply!

Does the off work without issues on other devices? I don't use stick mount as much because es file explorer always works for me now. Did you look under the local section in es file explorer, it should be under the option for SD card on the. LHS window that you pull out.

yes I have looked under SD card in ES explorer. And Im assuming you meant otg and not 'off'? I have not used it on any other devices no. And it very well could be the issue that the cable is no good but that is part of the troubleshooting that I wanted to go through. I made the otg cable myself and I literally made three of them thinking maybe I was doing something wrong with the the fabriccation of the cable but I am 99.9% certain that there is nothing wrong with the cable. I made it a Y cable with the 4th and 5th pin on the mini usb male shorted (jumped). Then with the male usb type a plug only having pins 1 and 4 populated. I have made plenty of usb cables in the past and like I said made three of these before I was sure that the cable wasnt the problem. The cable when plugged in charges the phone fine just even with the otg troubleshooting app doesnt show a mount point. I couldnt even find it in the shell as a charging device yet it is clearly charging

Yes I mean OTG, although my keyboard disagreed...
It could be the way the device is seeing the cable (I know some cables are charge only) maybe the phone sees it as one of those? I would try to find someone else you know who has a Android phone and see if it works. Its odd that it doesn't work, I have a OTG cable and 3 OTG flash drives that I use, but I haven't had any issues with my phone finding them.

When you say otg flash drive do you just mean flash drives that you have dedicated to otg use or is there something special about them? How about the permissions or the way the flash drive is formatted? should work with just a normal fat32 formatted flash drive right? And I tried getting the cable to work before I even put the charging option on it thinking maybe the flash drive needed power and didnt work than either. How about when a flash drive has a led light for an indicator on it. when you plug it in to your phone via the otg does the light blink during activity?

so I tried a usb with a led indicator light and it does indeed light up showing me that the cable is in fact good and that the usb is being recognized but I still cant mount it or see it in the file systems.... The light flashes on the usb when the phone is booting and when I plug in the usb and still no recognition in files

Thumb drives will work anyway assuming they are formatted correctly. I believe they need to be ExFat not Fat32 to work with OTG.

I did try exfat also and no luck there either... the cable does work on other devices so wtheck? Anyone else can give me some help please? Perhaps a "member" could help....

Massive Storage not working in T813, computer does not detect

Hello fellas,
I have a problem with my brand new T813 running the latest official firmware available (Android 7).
Massive storage is not working, my computer running Windows 10 with updated samsung drivers has failed to detect it. The device charges, but I am unable to modify the usb options, regardless the choice MTP always remain.
I have tried with three different cables, all of them work fine with my S7, the computer never detects the device, eventhough it's charging. This means it is not a problem with the device's micro usb port. I have the latest drivers, and I have also tried with all usb ports. None of them seemed to do the trick.
The computer has faulty usb 3 drivers, ever since I have installed Windows 10, the speed is not what used to be with the previous configuration. I have the same drivers, I don't understand what's wrong.
Any help would be appreciated, I have tried most solutions mentioned on this community and they didn't work. I can't flash the device because it is never detected. The problem still persists after a restablishment via the menu.
Download mode shows
QUALCOMM SECURE BOOT: ENABLE (CSB)
FRP LOCK IS OFF
[UPDATE] 06/08 11 AM
Left the device at SAMSUNG ARGENTINA repair shop. Also had to pay 300 pesos (around 20 dollars) as a diagnostic fee, they told me that if I accept the repair cost later on, they would discount the 300 pesos I have paid out of the total price. And if I don't, they will keep the money.
Will update again when Samsung calls me in a couple of days. Maybe this monday, I hope so.
[UPDATE] 06/08 15 PM
I have just received an email from BGH, which is the SAMSUNG ARGENTINA official partner for repairs. They told me that the problem is a FAILURE on the SUB board.
http://www.ebay.com/itm/Micro-USB-C...g-Galaxy-Tab-S2-9-7-034-SM-T813-/322414846816
The good thing, is not that expensive. The bad thing, this tablet hasn't arrived officially to Argentina, and since it has been bough in Chile, the guys at SAMSUNG ARGENTINA had to request an international order replacement, which I have been told it could take some time. But they will eventually get the piece.
Will update again.

Thanks for replying, please refer to first screenshot. No Mass Storage option appears after connecting device. MTP option seems to be forced, i am unable to change it.
The tablet is brand new, but the guy who sold it to me said that it has always been working. He even told me that it has been barely used, and that the device is recognized when connected to an usb audio system. It has been upgraded to 7.0.1 a couple of days ago, maybe that's the problem.
I have just tried with a macbook air and it didn't detect it either, it is only charging. The same computer has detected my S7.

I didn't know mass storage is not used anymore, I think my S7 does have it and it works. I will try at work tomorrow.

When the problem appears with different USB cables and in different computers, as in your case, you have to look into the possibility that it may be a hardware issue.
I hope I'm wrong about this, but it sounds like the DATA+ or DATA- pin is damaged in your micro usb socket (pins 2 and 3, see http://pinouts.ru/PortableDevices/micro_usb_pinout.shtml)

Yes, I'm afraid it could be a hardware problem. But that would also mean the guy who sold it to me is lying. I have to say it, the device looks like it has been treated with care. However, i have noticed the plastic has worn out a little near the usb port, those black marks could indicate not so much care when plugging or unplugging the cable.
I hope we are both wrong about this. Tomorrow i will know. Fixing this is a pain in the ass, right?

¡Che! Replacing the microusb receptacle would not only be a pain the ass, but if you make a tiny mistake while soldering or desoldering you can end up with a bricked tablet.
Anyway, let me know what you find out tomorrow, good luck boludo.

Actually not too bad as the Micro USB port is a module and can simply be swapped out.

I didn't know this tablet had a modular micro usb port, that's great ! :good:

USB data transfer not working.

So i bought a used A2 for 5500 INR.
At first i thought it was a bargain but soon it turned out to be a nightmare.
The phone is full of bugs.
Worst one is that the phone only charges through the usb port. No data transfer of any sort. like an old nokia pin charger.
OTG doesn't work. It doesn't connect to the PC.
Whenever I plug in the OTG/connect it to pc, the usb options are all greyed out (same in the developers options default usb preference).
I can't even use Gcam now bcoz the PC doesn't recognise the device at all, so can't enable Camera2api, can't root, can't install ROMS... can't even buy a new phone cuz i have no money ???
turns out my phone also have the slow Emmc issue ?....read speeds are okay but write speeds are very slow... specially Random write (~10mBps).
I read many people have faced this issues. All those Posts are old, has anyone found a solution.
