USB Device not recognized - Samsung Galaxy S9+ Questions & Answers

I'm not sure if it was the recent windows update(1803) or if my phone is ****ed.
I've tried every USB port, the original cable that came with my phone, the cable that came with my HTC 10, and 2 other cables I had lying around. I also tried factory resetting my phone. None of this worked.
I've tried a few combinations of uninstalling and reinstalling the USB drivers.
I don't have another computer I can use to test with.

Same problem here, can t connect my phone to pc anymore. It worked when i both the phone for 1 week or so and now... nothing. The sound when you connect the cable to the laptop is gone and also the allow and / deny notification you get on your phone.
In downloading mode odin sees the phone and the laptop is makeing the sound.

Whenever you connected your device to the computer, was the USB computer connection on Media Device (MTP)? If it's not on MTP then the computer may not recognize the phone at all.

I have same problem with my S9+ .. I try to install some update to Windows 10 (MTP Drivers) and nothing...
In dawnload mode, also ...don't recognize

This may or may not help, is Bixby updated and configured? I never used Bixby, I turned it off and used Nova Launcher and could not connect to the PC no matter what I tried so..... I turned off Nova Launcher, re allowed Bixby, went through the many configuration nonsense and the phone now connects to the PC. When I plug in the cable the phone shows up as another disk drive and if I click on it, I get internal memory and SD Card and can read or write to either. I've no idea why but apparently Bixby is needed to connect the phone to the PC?
I re activated Nova Launcher and it still works so give it a try.
NOTE: Bixby must be allowed to update first.
Hope this helps at least one of you?

[Q] USB problem

Yeah, so i've read plenty of topics about USB problems, but none gave me the
anserw.
I'm running Villain ROM 3.0. I just cant connect my phone to the computer (Mac).
It work well before also after flashing Villain.
What i tried:
1. connecting my phone without usb debuging ->phone gives the sound and report in the notification bar : "MTP - initializing" then "USB Connected, MTP-connected" But it does not gives a connection with my mac.
2. Connecting my phone with usb debuging ->phone gives the sound, but nothing happens. nothing in the notification bar neither on the computer. It's strange becouse before it was making the same sound and giving me the info in the notification to connect.
3. I've also tried KIES air it works fine. i can see my phone content, but when im trying to send one file (130mb) there is no reaction to this.
Also some time ago i was able to get usb working by simply choosing usb debuging and restarting phone.
But now i have no acces to my storage
Please help
I have a similar problem.
When I connect my SGSII to my PC (with USB Debugging On) I see 2 Removable Drives in Windows' Explorer. If I click on either one I get the "Please Insert Disk". If I connect to the same USB with USB Debugging off, then Kies Starts but does not connect.
Now the weird bit, if I do the same thing in the next USB port, then everything works fine.
Going back to the first USB slot then the problem reappears.
The 2 USB slots are next to each other and go back to the same controller on the motherboard. I have removed Kies and reinstalled Kies. I have uninstalled all the drivers. I have even changed the USB cable. When I plug a USB External Hard Drive into either USB, it works fine.
Maybe the phone just likes the one connection per computer. I'll have to test that out in my work's PC.
Update:
managed to get a microUSB cable and tested it on my work's PC. Exact same situation. Both PCs run Windows XPpro.
Has anyone else noticed this?
Now, when you said that, i checked with my second usb por, and everything works fine .
So thanks for your help. One working with sgs2 usb port is enought for me

[Q] Connection problems

So when i try to connect my galaxy to the computer nothing happens. i plug it in and it will start to charge but the phone will not have recognized the fact that it is connected to the computer and the computer doesnt even say "unrecognized device" how do i get the phone and omputer to recognize each other?
Did you install drivers for the phone? What operating system are you on?
yes i have. ive tried both osx and windows 7 and i have made sure to download teh drivers for each
Have you tried to connect it in usb debugging mode? (goto settings, applications, devlopment, check debugging mode?
(I dont know of it will help, but it would be the next thing I would try)
And try different usb ports. I have heard before that it can help.
yeah ive tried all of that it and still nothing, the switching usb ports too
Did you restart the computer after you installed drivers?
I would try installing Samsung Kies (from samsung website, GS2 support page). It also installs drivers and fixed a problem I had with connection.
If all these don't work, I don't know what to tell you. Sorry. I am sure someone here with more experience will be able to help.
yeah haha ive done all of these unfortunately and still nothing, thank you for you suggestions though
Kies had an update within the hour of New years (Pacific).
I discovered this morning that USB debugging mode MUST BE OFF for Kies to recognize and connect to the phone. I'm currently backing up my device in this mode right now.
"Kies Air" also works well, without having to worry about any USB issues.
"Droid Explorer" connects fine with debugging turned on. I have to wait until backup is complete to see if it works with debugging turned off.
I'm having USB port issues right now, so your mileage may vary.
Hope this helps.

[Q] USB issues Odin

So the ota screwed up my phone. I was able to connect and intstall the stock eoh3 for xda the phone now starts up but I am unable to connect USB to root or flash any new rooms with Odin I can only connect Odin if the phone is booted up and debug and mock locations are on. If I pull the battery and put it in download mode it will not connect to the pc it just shows as an unknown device. I have reloaded drivers ect but not getting anywhere. Any ideas?
Try another cable if you have one, and try putting the drivers on another PC. For reasons I still haven't figured out, my home desktop PC quit connecting a couple of ROM's ago, and it won't even let me reinstall the drivers. I have a laptop that works fine (so I haven't gone into major troubleshooting) and my work PC also connects fine.
If the same issue repeats on other PC's and cables, there may be something wrong with your mini USB port. I had to have mine replaced a few months back.

[Q] Doesn't connect to PC

Hi, I have a Galaxy Player 4.0 that I rooted with SuperOneClick. It was working fine at first then a couple of weeks ago, I noticed that my PC no longer recognizes it as a device, it just charges when I plug it in. So, I looked around andn tried a few things:
Restarted it several times
Tried with all the different modes in USB settings
Tried with different cable
Tried with two other computers, a Mac Mini and a Win7 laptop
Tried to unroot, couldn't get that to work
Did a factory data reset
Nothing works. I can't remember anything I did since rooting that would cause this, except I installed the Samsung Kies driver on the PC. I can't remember if the USB mass storage was working after Kies. Does anyone have other ideas?
Bump. This is rather a big deal, as I cannot transfer files between my PC and Galaxy player in any way other than over WiFi, which does not work reliably. I don't have a microSD card adapter either.
You might want to check if anything related to samsung/android appears in the device manager. Alternatively, to use heimdall I use Zadig to switch from samsung's driver to libusb but it does show you everything connected to your computer via usb when you check the option to list all devices. You should try this with and without usb debuging enabled. If nothing shows up you know it id your player that is at fault.

Thanks,
The first time I plugged it in without USB debugging enabled nothing showed up, when I enabled USB debugging, in Zadig and Device manager there showed up an unknown device, trying to update driver in Device manager showed that it already had the best driver, and in zadig driver replacement failed. Now, when I plug it in, either with or without USB debugging enabled, nothing shows up anywhere. I have tried with other computers and other cables, and nothing works, so I am pretty sure it's the player. I am willing to to a complete factory system reset, but I don't know how.

I'm having the same problem with my rooted 5.0. Although it's not a huge problem for me (I use dropbox for file syncing) I would love to sort this out, let me know if your factory reset works!
You can find it in the Privacy section of the settings menu.

I suspect you have a faulty usb connector on your device, but it doesn't hurt to do a factory reset. But you might want to backup your data first Did you try to jerk the usb cable in your player? A loose/broken connector would explain all your problems. Even if it is a software problem, I can't see how to flash your device with the original firmware since you don't have a sdcard & usb doesn't work...
Btw, I was referring to zadig only to show the devices attached to your computer, not to change the driver!

Thanks, I only tried to change the driver because it showed no driver already installed. I have a bit of electronics background so I may crack it open and take a look at the connector. I already tried the factory reset in the privacy menu, but that only wipes data apparently, not the system. I do have an sd card, I just don't have an adapter to the PC.
EDIT: After wiggling the cable around a bit, it showed the USB icon in the status bar, so I clicked connect USB mass storage, but the computer still showed a badly installed driver and then after some more wiggling the icon disappeared, so I am pretty sure it's a problem with the connector. BTW, how would I flash the stock firmware to unroot?

[Q] Make windows 7 detect S3 in download mode

I've searched around a few threads but not having much luck on this. I've started on a different computer totally from scratch several times and it just doesn't recognise that the phone has been plugged in. It's really quite irritating as the ODIN CF root method is literally 5 clicks and should take about 10 seconds to do.
I plug the phone into my PC while it's on and it detects it as the USB device and I can go into the folders and copy music on etc etc.
I switch it to download mode, plug it in and it does sod all. No windows beep to say it's plugged in a USB device. If I open ODIN then plug it in it's not doing the COM added.
I've tried installing then uninstalling kies then rebooting, installing just the USB driver, uninstalling, rebooting, reinstalling, rebooting. Just NOTHING seems to make my PCs detect that I've plugged the damn phone in when it's in download mode. It should be such an easy process but I'm left banging my head against the wall mid way through because it just refuses to acknowledge the device. I unplug, switch it on, plug back in and there it is, device connected. I've tried different computers, different USB ports. It doesn't show up in device manager even.
So my question: any idea as to why it will detect when the phone is on normally, but will not even think it's plugged in when switch on in download mode? And of course, how to fix it would be useful!
OK I fixed it.
I uninstalled the USB driver and restarted.
Downloaded/installed a new USB driver (specifically SAMSUNG_USB_Driver_for_Mobile_Phones_v1.5.23.0-retail).
Went to download mode and it picked it up straight away! ODIN worked in 10s as expected.
Found the instructions here, for reference. http://www.modaco.com/topic/361286-...-phones-15230-for-win-87vistaxp-adb-fastboot/
