I've had this problem before, but I have always been able to fix it by uninstalling ADB and drivers, through WUG's toolkit, changing cables, device manager/update drivers, jumping up and down while spinning and plugging cable in, among other things. However, this time is different and I'm not sure if it is because of M on my phone or the Windows 10 update. This problem has been going on for over a month now, and I've had both since it started. I've tried all the above mentioned things, along with everything else I can find, and none of them work.
The only way I can get my computer to recognize my phone to share files is to go into device manager every I plug it in is to; go to device manager, right click to update driver, select do it from my pc, select driver in folder. After doing this it works perfectly fine, but I have to do it every time I plug my phone in or every time my phone turns off while it's plugged in. The error message I get on my computer is "USB device not recognized" when I go into device manager it says "device descriptor request failed" It does this on both of my PCs. Any ideas or help would be greatly appreciated!

I think I'm getting something similar since I've installed "M"....
Under:
Settings -> Developer Options -> Select USB Configuration
It say's it's set to "MTP (Media Transfer Protocol)"; it really isn't. When I plug the phone in, under Win 8.1, a desktop window opens with "AOSP on Hammerhead" (or something like that), but there's nothing in it. Now for some magic....
With the phone in one hand, and the mouse in the other:
1. Open Settings -> Developer Options -> Select USB Configuration
2. Touch "MTP (Media Transfer Protocol)" (even if it's already selected)
3. Listen for the PC/Windows Desktop (it should give an audible sound)
4. Immediately click on the "AOSP on Hammerhead" text in the path listed on the open Windows widow ("This PC -> AOSP on Hammerhead")
5. You should see an "Internal Storage" folder appear
6. Open the folder, enjoy MTP

Hey there,
I'm having issues trying to sync my phone with my computer. When I connect my phone, nothing happens, Zune doesn't launch, and when I open it, it doesn't show my device as connected. I've tried everything I can think of, different USB ports, rebooting both the phone and my pc. I'm running windows 7 64 bit, and it was working before. Anyone know what's going on?
Thanks for the help!
p.s. I tried uninstalling the drivers for the device, and upon reinstall my computer said it was installing drivers for "Microsoft USB Sync" thought that was weird...
try making it forget your device (don't have your phone plugged in). to do this, click on the phone icon in the bottom left of zune, click view sync options, and then on that screen click forget device.
after this, try and connect it again.
Didn't work, i plug my phone in, and Zune still says I have no device connected
does your computer make it's sound when you connect the phone (device detected sound)? if not, you might need to reset your phone (settings > about > reset phone). if yes, does it show the eject icon in the notification area (system tray)?
yes, it makes the sound, and yes it shows the eject icon... this is very odd
I had this problem too. When i went to the Device Manager, it showed unknown device when i plugged my phone in using the USB cable.
Here is what I did (Windows 7). If you see an unknown device, right click it and select Update Driver Software. Click Browse my computer for driver software, then click Let me pick from a list of device drivers on my computer. Then click on the Have Disk button, then browse to C:\Program Files\Zune\Drivers\Zune and select WMZuneSerUSB.inf. Then select Windows Phone 7. Hit Next and you should now see your Unknown Device show up as either Windows Phone or the name of your phone under Portable Devices in the Device Manager.
Actually, I forget if it is WMZuneSerUSB.inf or Zune.inf, so you'll need to try both.
Hope this helps.

I had this problem with my Samsung Focus.
Try using the cable that came with the phone, not another one...
That is what worked for me..
Nothing seems to be working, I may have to reset my phone, which i was hoping to avoid...
Did you perhaps use the hidden Tethering feature? If so, then change that option back to "Zune sync" and you're done. It is not possible to use your phone for Zune sync and tethering at the same time, for now.

Now that you mention it, I can't remember if I did that on this phone, or my last optimus that had to be returned. What exactly do I need to do to change that back? I totally forget the process...

Dial ##634# to go to "Diagnostic mode"
Then enter *#7284# to go to "Micro USB Test"
You then have 3 options to choose: "Zune Sync" (default), "Modem, Tethered Call" and "Modem, USB Diag". Change it back to "Zune Sync" and you'll be able to connect with Zune on your PC.
Anyone else having this problem? Zune doesn't recognize my WP7 phone on a laptop with Win 7 x64, but same phone+cable works on a laptop with WinXP
The Win 7x64 laptop does connect to the phone - I tried the above tethering change and was able to pull files from my WP7 storage - but when I switch it back to Zune synch it doesn't work.

Is this specific to Samsung models? I can't get to the micro USB test on my lg optimus
EDIT: Problem solved, I had to switch back to MS COMPOSITE, and now it works fine.
Hmm yeah I have this issue on my HD7 with my PC running Win7 x64.
The phone connects fine on both ends (sound on both, phone charging, shows up in Device Manager as HTC HD7), but the desktop Zune software often does not show it as being connected. Restarting the phone and PC generally doesn't help-- just have to wait a few days until they start syncing again.
The sync setup seems really flaky (like the earlier days of ActiveSync).

i have the same problem...
Are you using virtualisation software? It's USB arbitrator modules for forwarding devices might have messed up things. This happened over here before with VirtualBox.
Exact same problem with Win7 Ultimate x64. Device manager saw my phone but zune would not.
I did the steps above to change my phone to usb tether, rebooted, then back to zune zync, rebooted, and now the zune sees my phone.
Thanks for the help.
How can I fix my problem of 'No USB connectivity' ?
My Samsung GS3 has stopped giving me the notification that I connected to my PC. It still charges, but I can't access my files. It's been happening for a few months. When I cable up, after a second, it chimes audibly (pong-ping), but the pitch fork icon for USB never shows, there is no notification, the PC never does anything. Drop box works, Wi-Fi works, NFC works, Phone works. Samsung model SCH-I535 running Android 4.1.1 on Verizon. I have not rooted, or ROM’ed but this may take me past that brink.
I've tried::
Numerous PCs and USB cables
USB debugging (& Stay awake & Unknown sources) checked and unchecked
Unmounted & remounted SD card
Asking the PC to look for new hardware
Removed and re-installed PC drivers both from Verizon
(Verizon_Wireless_I535_GSIII_Samsung_USB_Driver_v1_4_6_0.exe)
& from “Samsung GS3 Int ToolKit”
(SGS3_International_ToolKit_v6.0.exe)
:: but nothing has fixed it. :crying:
Please don’t tell me to use a Wi-Fi app, Kies, All Share Cast, or S Beam. I want my phone USB fixed.
Thanks;

What are you expecting to see when connected? The new Android o's doesn't mount the device as a drive letter - you have to access it via MTP. This means you won't see it as a drive. You need an MTP capable program to sync, or you can see the contents within the "portable device" entry.
Without proper, working MTP drivers, the phone may not show the connection. Under XP I had many issues getting the driver to work. I think other windows versions have similar issues. I had to force-load the drivers from the "eclipse" (I think) sub folder after extracting the files in the installer.

I fixed this by doing the following:
1. Reboot phone into download mode.
2. Plug phone into PC.
3. It should install some drivers at this point.
4. Remove phone from PC and remove battery to shut off phone.
5. Put battery back in and boot phone.
6. Plug phone into PC.
7. Profit??
Working, thanks!

As I tried 'download' mode, it worked, sort of, like you said. My PC found new hardware and installed MTP and ADB drivers. My procedure went more like this:
1. Remove phone from PC and remove battery to shut off phone.
2. Plug USB cable into PC.
3. Plug USB cable (other end) into phone.
4. Put battery back in and boot phone but…
5. As the phone boots, hold down Volume up and down
6. This should reboot phone into download mode.
7. PC should install some drivers at this point.
Phone was in safe mode, but another reboot changed that.
Their must be some magic in that old silk hat you found. Opps, sorry, wrong song. :victory:

Edited following @Shawnsch's post, as I referred to MTP/PTP as "mass storage" which might be true but is confusing
I just got a Moto G (XT1032) 3 days ago. Like my previous phone, I've rooted/CWM/CM11. I'm getting pretty confused because the PC to USB link side of things isn't going smoothly like my previous phone did. I'm probably just confused, but not sure where I'm muddled, and I need things set out clearly.
On my old phone/firmware (Samsung + 2.3.x / CM7.2), I installed a manufacturers' USB driver (Win7 or Win8 x64) and ADB on the PC side. The phone then presented itself on connecting as a mass storage device and was assigned a letter, and also responded to adb if that was used too. On the phone side a USB icon appeared in the status bar when connected.
Fast forward to my new Moto G and... yeah, chaos. Sorry if this is a bit of a brain dump, I'm confused myself.
I got the basics fine - Motorola x64 drivers (Motorola_Mobile_Drivers_64bit.msi, 3533312 bytes) and TechGlen's adb/fastboot (v1.1.3). They both work as I've had adb install and file copying both working at different times, and unlocking+flashing was fine. But I'm not getting a stable situation where I can use both (MP or PTP) and adb. When I get the device recognised in "My Computer", it takes forever (with driver uninstall/reinstalls and pure luck) to get adb back again; once adb's working it's a nightmare getting Windows Explorer file transfer working again. I'm in and out of device manager and rebooting - I'm sure something's not done as it should be but what?
Each time I re-install the devices I get several kinds of device/driver it "knows" about - ADB Interface and Android device are both listed, but each has several drivers to choose from (Android ADB, Android composite adb, Mot composite adb, Mot single adb,and several others). I have no idea which to use or the differences between them. Sometimes it says "drivers not installed" with a yellow mark, but other times it says "this device doesn't need drivers" instead. Right now Device Manager shows both an Android device and an "Other devices->Motorola ADB interface" (The 2nd of those has "drivers not installed" although surely I've installed them many times now), and MTP/PTP aren't working since, although it audio-alerts on the phone and pops up in device manager, and sometimes I get the "driver installing" taskbar item, no storage device appears under "My Computer".
When I did get them working, the Moto no longer lists as a drive with a letter, it's listed as some kind of media device instead, so some software and disk management utils can't access it. It appears instead at the bottom of "my computer" as a separate kind of item. I also can't find how to enable/disable/control the USB connection in CM11. On my previous phone there was a clear status bar icon.
My questions are:
Which drivers and setup should I be using, to get Windows Explorer recognition and adb to both work smoothly? Is there a difference between an adb connection and a MTP/PTP connection in CM11 (by which I mean, do I need to "change mode" between them or can they both be used in parallel?)
Where is the usb status bar icon, and how do I disconnect/reconnect/turn on+off USB at the phone end
Can the Moto appear as a "regular" drive letter so that disk management tools with USB disk capability can act properly on it?
Thanks!!
I believe mass storage mode is gone now

Yeah - referring to MTP/PTP as "mass storage" wasn't a good idea. I corrected my use of "mass storage" in the OP so people reading this won't get misinformed.
Odd thing I found as well - I got one machine to connect - if I put it in MTP mode it'll be recognised in Explorer but not ADB, and if I switch the Moto to PTP mode then ADB will not recognise it but Explorer won't.
hi ihave problem with mtp driver in moto g.pls help
I'm trying to use android file transfer on my macbook and every time i plug in my phone it automatically selects the "PC Software" option and it loads up a screen that says "Installing PC Programs.....Please check your PC" but nothing happens on my PC or phone.
I select the Media Sync (MTP) option on my phone but it will literally switch it back to PC software on its own. I've even unplugged my phone, changed the setting and plugged it back in and it keeps forcing itself onto the PC Software option, i've even gone so far to restart my phone and computer.
I have the USB drivers from LG for my macbook and phone installed but it's not working. To make things more annoying I was using android file transfer like 3 weeks ago but for some reason this keeps happening.
Any help would be hugely appreciated.
Thank you.
Brand New Unlocked S8+... Tried to connect it to my PC to use a previous copy of smart switch backup but it never connects.. Windows Explorer never displays a mounted drive either. Smart Switch Eventually comes back with Failed to connect to the device.
The Phone displays the "Attention The connected device is unable to access data pm this device. Reconnect the USB cable and try again...."
Phone is on Transfer Media files (MTP)
USB Debugging is one.
Device Manager says "Samsung Android Phone - SAMSUNG Android ADB Interface" two times - No red or yellow exclamations.
I've removed the software in device manager and restarted both the phone and the laptop multiple times.
I updated Smart Switch and did More\Reinstall Device Driver.
Does anyone else have any workarounds for this? I found one article (https://www.recovery-android.com/connect-samsung-to-computer.html) but still no success.
I actually have the exact same issue on windows 10. Anyone figured out a solution?
Doesn't seem like there is much help here on the 2 Samsung formums I posted on....
I know its not my windows profile as I have tried 3 different profiles as well as safe mode.
Tried 2 different sets of Samsung USB drivers and no improvement.
Like I said I had no issues on a windows XP machine or a windows 10. I didn't even need to install the USB drivers/Smartswitch on either of those machines.
We can't be the only 2 people!

Firstly, i cannot give you direct answers.
Just my thoughts.
i have a S8+. No root stock as is.
I have Lenovo laptop Win 10.
From day one, out of box, i connected
S8+ and it connected. I can do whatever
i want. Transfer data, photos videos.
ADB etc
So it should work...?
However i do realize there are quite a few things to consider......
Samsung drivers on laptop and a few other
issues..... eg
For one,
have you enabled
in Phone /Settings /Developers Option /Usb debugging.?
Normally first time when you connect
With pc /laptop you should get
a small pop-up message(on device) to allow
phone to connect.?
(that's my experience, over years)
Good luck
Yes, USB Debugging is on and connection is set to MTP.
Windows recognizes "USB Android" but dosnt install the driver successfully.
It will appear as a modem in Device manager but nothing is mountable.
I have 2 desktop pcs with win 10. One with samsung software Kies 3 and smart switch installed and the other no samsung software. Both find the device Galaxy S8+, in device manager under universal serial device controllers i have Samsung Mobile USB Composite Device. You have an adb driver I think because you have usb debugging on, i would turn usb debugging off. The pc should find a device connected to the usb and download a driver, once done the device is recognised as galaxy S8+ in my case but will not communicate with the pc until the phone has given permission. On the phone will be a message asking you to allow the connection. Hope this helps ??

Firstly i do understand that you
must be quite annoyed trying to figure
out issues. (I would) Thankfully i don't.
Bottom line is that it should work..!
My experience confirms, that S8+/laptop Win 10 works.... 100%when connected
However a few suggestions.
If you feel you checked all checkbox.?
However you never said anything
about popup notice ? granting premission
for device to connect.?
So device /laptop /pc is not "seeing" each other?
All Samsung devices I have used, first time connection gives me this popup a notice
Can't remember exact wording.
Something... eg
Device id 5786446.......
Have or does your other Samsung devices
connect etc.?
Have you tried connecting to a friend pc laptop.
An option is to go to a Samsung Care Center
and as them to test and connect.
My experience (in past) is that they should
assist you.
If it connects to friend pc or Service provider /Samsung Care Centre.
Then surely it has to be your pc/laptop?
So I turned off usb debugging and revoked the permissions on the phone, connected it to my PC.
Samsung Android (with a Yellow Exclamation) was already present in Device Manager under "other devices" so I uninstalled that.... and rescanned. My laptop attempted to reinstall but it generated a Driver Installation Failed message on "SAMSUNG_Android" - no driver found.
Device Manager once again shows the Yellow Exclamation Point
I would go on to Samsung support look up the phone and download the usb driver and install from the download. Good luck
I've downloaded the drivers from Samsung 2x.

I can vaguely remember that i had this same
issues with my Note 5 and Win 10.
This was many months/year or two, ago.
I also had yellow exclamation etc.
Further in Device manager( laptop) kept installing wrong Samsung drivers.!
I uninstalled drivers/installed and battle for a few months like this Then one day Windows
did an update and in update i noticed
Samsung drivers included etc. (must have been correct)
Ever since that update i had no issues again.
Bottom line... some drivers issue?
Not S8 +?
Good luck

In the past I had this problem I downloaded USBDeview to my PC and deleted all of the old Samsung drivers, after rebooting the PC the phone was able to connect with the PC.
Tried USBDeview and removing the Samsung drivers but no difference
Still unable to connect.
I'm having this problem as well. I'm still trying to work it out, but when I remove and re-add the device through Device Manager I get this error: "An existing device was found that is a duplicate of the device being manually installed" and the device DOES connect as a camera, just not for full file transfer.
I had the same problem and tried many of the fixes, including different USB cables and different computers and different phones. I finally figured out that the case I had on the S8+ was the problem (at least for me). I took it off and everything works.
Hi, i have a pc with windows 10 . In device manager under universal serial device controllers i have Samsung Mobile USB Composite Device. i think you should meet best mobile shop.

I have Windows on Lenovo Laptop with latest Windows updates installed. Yesterday, I downloaded Samsung Smart Switch unlocked the phone and connected it to the laptop. Smart Switch found it immediately and I did a backup. I did not need to check Device Manager. It must be a drivers problem as mentioned above.
Note 8, getting "Attention The connected device is unable to access data pm this device."
And I am only able to see some files, Sammy is a crazy fool, this is basic stuff
installed the windows fall update a week ago now connect my phone to my laptop and nothing is recognised, no phone memory and no memory card just a empty space when i click the icon where my phone should be, i've had samsung drivers installed and they have worked fine so far till today, any ideas where to find the latest drivers? and what else i can do to get access to my phone on my laptop?
solution that worked for me
On my windows 10 PC, I opened device manager (open up start and just type 'device manager') and under portable devices there was a usb device called MTP USB device or something like that (I forget the exact name) with a small triange and an exclamation mark next to it. I clicked on that and then clicked "update drivers." When the prompt comes up I chose the automatically look for drivers option. This fixed the issue and now my Galaxy s8 is recognized (it no longer says MTP USB device or whatever it was). Hopefully this works for others as well. You can also probably download the usb drivers for the phone from samsung.
