USB Problem

Something happened with my HD2. USB charging functionality works, but connectivity - not.
Computer shows message "USB device not recognized"
Tried on different comps, XP, Windows 7 - nothing. Soft reset, pulling battery, changing options on USB in Settings didn't help.
Any ideas?

You have ActiveSync (XP/2000) or Windows Mobile Center (Vista/7) installed?

Have you tried a different usb cable?! Anyone you know have a HD2 you can test it out on?! If something doesnt work on my HD2 I try it on my girls just to double check?! When you plug it in do you get a the option of choosing active sync or hard drive?!

Another thing it could be, and I need an answer to this myself, is that when you first plug the phone into the PC, the device presents the option of ActiveSync or Data Transfer, with an option of "Do not show this again". If someone selects Data Transfer, and clicks Do Not Show Again, how can this be reversed or undone? I have a user that cannot Explore through ActiveSync because he likely selected this option.

Jimbo, you can re-enable that in settings-connections-USB to PC, there a checkbox there labeled "ask me first about USB connection..."
DocAlex, did it connect properly in the past? If so, I'd start with toreone's suggestion and find a way to test with a different cable and/or PC.

Yes, installed. Also tried different cables, one of them was it's OEM cable.
Manipulated with USB setting on phone - didn't help.
Checked wet indicator - it's white.
Did nothing with - on some morning, after full night charging, connected to USB and got it. Bluetooth sync works on same computer...
Looks like USB controller died

Did you try connecting to a different computer?

Thanks Phunkeefunk!

Finally, after and hour on tech support call, T-Mobile agreed to replace it. Already got new, used SPB Backup, very easy transferred all from old one to new. USB obviously works on new.
So - some time USB controller can die ...

problem with usb connection?

Hi
My problem is that when I connect my sm-n900v to my laptop no usb icon showing up in notification bar device only charge.
I removed the driver and install it again not working.
I disable usb debugging not working and enable it not working
anyone know how to fix this problem?

I'm having the same problem. This started only after lollipop update. Device charges, but laptop does not "see" usb connection. Nothing in system tray. Nothing in device manager. Current version Kies just installed, but doesn't see phone when connected. Restarted both laptop and device disconnected and connected.
SM-N900V Android 5.0
Windows 7
Don't have a clue how to fix this. Any ideas? Thanks!

Thought I'd post my update. While my original USB 3 data/charging cord seems to charge flawlessly & quickly when plugged into the correct 12v OE wall charging adaptors, there is apparently a problem with data transfer. I think the cord I'd OK, but its loose when inserted into the port on the device. If I hold it JUST so, it works fine. I suggest patient cord manipulation to determine if this might be the problem for others as well. Might be hardware repair time.

Hi
I found this solution and it's work now
With the device plugged in:
Dial ##366633#(##DMMODE#)
Disable DM Mode
Disable USB Debugging Mode (Menu> Settings> Developer Options)
If you don't see Developer Options, Enable them by going to Menu> Settings> About Device and Tap "Build Number" 7 times. This will enable Developer Options.
Allow Drivers to load completely. This can take up to 5 minutes.
Device should now appear in device manager as Samsung Mobile USB CDC Composite Device
Now..With the phone still plugged in, turn off and turn on (Restart the device )
Again allow the drivers to load.
you will see the usb icon showing up in your device..
:good::good:

i knew i wasnt crazy and i had a usb menu show up on connect...btw a temp fix to not showing up, download more shortcuts, open app click activities -> click settings -> USB computer connection(Settings$UsbSettingsActivity) and select MTP or USB 3.0. You will have to do this everytime you unplug,(or set a shortcut on homescreen to open setting panel)

Have to change USB connection to MTP every time in order to get Android Auto to run

Currently I'm having to manually change the usb connection to MTP every time I plug into my car to get android auto to run. Is there any way around this or to set it by default to MTP? I've tried doing it through developer options, but it doesn't stick.

Same issue it worked when I turned off ADB debugging but then stopped working seems like another bug will have to wait for them to sort out really annoying for Android Auto users.

Under "Developer Options", there is the "USB configuration" setting. Mine is set to "Charging" but I can change it to "MTP (Media Transfer Protocol) or PTP (Picture Transfer Protocol) or RNDIS (USB Ethernet) or Audio source or MIDI. Are either of these options what you need?
Sorry, if I'm missing something with the problem you're facing, but I thought I'd throw out what I see. Disregard this post of it's something else you need. Good luck!

I'm having the same issue. And as the OP stated, we are changing it in developer options, but once you back out and go back to check it, it's back to charging mode. Been a nuisance as it disconnects from AA when it switches to charging mode.

It's super annoying. Hopefully a fix will be out soon, but doubtful

No option to change to file transfer when connected to PC

Good Morning All,
I had a quick question. When I connect my pixel Xl to my Windows 10 pc I get the drop down android system option to change from USB charging to file transfer.
On my Essential when I connect it makes the noise where windows notices it but on my phone I don't have the option to change from charging to file transfer.
I'm sure it is something I am missing but would appreciate any input. I believe it is a driver issue as my other windows 10 laptop recognizes it and I am able to change to the transfer files option.
I checked device manager and it is not showing up under portable devices.
Thanks

On my HTC 10, you can make the change manually by going to Settings>>More(last option under Wireless and networks)>>USB connection

Thanks I have the option to change it to MTP via developer options and it works fine where I get the notification on my other PC. I'm thinking somehow my one laptops driver may be bad as it recognizes my Pixel but not the essential.

Yeah, I was thinking there was a way in developer options as well, but I don't have my cable with me so it wasn't showing up.
I have an older laptop that makes the "recognition noise/ring" when I plug in my phone, but it takes like 2-3 minutes before the screen pops up asking what I want to do with it. Don't know if that could be your issue, but you may try just letting it sit for a few before unplugging it and see if that changes anything.
Or, it could be just like you say, bad driver.

Thanks I'm going to try and reinstall the generic driver and see what happens. Strange it works on one laptop but not the other. Gotta love Windows.

Try another usb port

It is usbc and only have one.
I plug my pixel in on the same port and it shows up in portable devices. With the essential plugged in my computer makes the noise that it is connected but it does not show up any where in device manager.
I uninstalled the driver with my pixel plugged in and re plugged in the essential still no go. I plugged in the essential and the driver was installed. It is strange as it shows up under my other windows 10 pc just fine.

I had the same problem and I eventually got it to work by using a USB A to C cord, not my usbc port on my laptop.

Had the same issue last night, turns out for me my computer recognized the phone and used the adb interface driver, had to go into device manager, Uninstall the driver associated with my essential phone, and then replug the phone in for it to be accessible via mtp

Yea the only problem is it doesn't show up in device manager. I uninstalled my ADB interface but still no go. I have a USB A to C ordered maybe that will work.
Thank you!

I also noticed that it didn't work in a USB 2.0 port for me, only in a 3.0 port. And my front facing 3.0 port on my desktop that I use for flash drives didn't work either, so not sure if there is some long cable signal integrity issue there, but USB 3.0 port was the only way I got it recognized via my computer

I did use this USB Device Viewer from Microsoft and found that it is showing up with this error.
Though not sure how I'm supposed to resolve it. https://imgur.com/w1tz12s
It is at least showing that it is connected.

Maybe I'm not understanding but on mine when I plug into PC the pull down menu shows charging and then I tap on that and get a menu that has file transfer and 3 others and I select file transfer. Have you tried that?

Can't be detected by laptop but can charge

My phone cannot be detected but I can be charge. It can't also detect OTG even though I flashed OTG fix.
Any solution?

Hi Random, here are a few things I'd try:
1. Try one or two different USB cables and see if you get the same results.
2. When the phone is connected to PC, you need to go to the phone and under the system notification, specify what you want the USB Preferences to be (Use USB for: File Transfer, USB Tethering, etc) just to make sure.
I can't help with the OTG as I haven't used it yet, but maybe one of the other members can shed some light on the issue. Good luck and I hope you get it sorted.

There's no system notification (a "P" should appear) when I connect it.

It's the cable that is bad. Try another.
Don't know about OTG fix.

I've used another cable, it's still the same.
But our desktop can detect it.

usb drivers
since your desktop can detect it try this.
connect it to your desktop and go into device manager and find what USB driver is being used.
now check if that driver is also present on the laptop. if not copy it over and restart the laptop.
