I can't figure this out. For some reason my Windows 10 computer doesn't recognize my Note 20 Ultra when it's connected to a USB 3.1 type A port. It's not my cables, I used them with my S10+ and they worked fine. The only way my computer will recognize my phone is if I use a type C to type C cable in the USB 3.2 type c port. Otherwise it shows up in device manager as "Samsung Mobile USB Composite Device" with a conflict and tells me the USB device malfunctioned and isn't recognized. I can't for the life of me figure out why my computer won't recognize my phone in any USB A ports.
The drivers are installed, the cables aren't faulty, and uninstalling the drivers and letting them install with PnP doesn't work. Does anyone have any idea what's going on here?

After hours of troubleshooting, uninstalling/reinstalling USB drivers and Samsung Mobile USB Drivers, modifying Windows' registry, etc. I've come to the conclusion that the problem might be the USB cable that came with my Galaxy S6. But there's a catch...
When I plug my S6 into my Win7 desktop (back USB port, regardless of 2.0 or 3.0) using the cable that came with it, a fresh device installation results in the phone registering properly, then reverting to "Unknown Device" just seconds later. If I plug it in again any time after that, it will say "USB Device Not Recognized" and register as an "Unknown Device" in Device Manager - all it will do is charge.
BUT, plugging my S6 into the same USB port in my desktop using both a cable that came with the S3 and another that came with the S7, they both result in a properly registered device in Device Manager which allows both data transfer and charging.
Riddle me this: The catch is, when I plug my S6 into my Win8.1 laptop using the original cable, it registers properly and allows data transfer and charging.
Is there an explanation for this? The fact that the original cable doesn't work with my desktop but works with my laptop sounds like a driver issue - though using different cables in the same desktop port working properly makes it sound like a cable issue...
When i connect the iwork the PC with the cable Type C it only charges
When I connect with USB 2.0 nothing happens ...
What I have to do to be able to transfer files between the tablet and the PC?
Thank you

Greetings!
I had this issue as well, keeping track of it via Device Manager on the PC. Sometimes, it says it's the Model #, other times (depending on if you're recovering, adb debugging) it will say is "ADB Interface". I'm in need of recovery and refresh for mine, which is how I figured this part out. It's not much, but open your Device Manager on your PC before plugging it in via the 2nd USB2.0 down on the tablet. Watch it. If on the Windows side, it should pick it up as a media device or the device model number. On the Android side, if USB Debugging is on (which mine already is, thanks to the last person who had it -- I bought it from Amazon.), the charging should show up on-screen, and the Device Manager (USB Device, last one down) should see it.
I hope this little bit helped.

When I plug in my Nvidia Shield K1 into my computer it only charges.....
My old K1 was recognised by my computer immediately before so I don't know why this one won't work?
Please note these things.
1. I have tried a different cable and connector
2. It was purchased second hand and bootloader is already unlocked with TWRP installed.
3. Have installed all necessary drivers on computer
4. Have put tablet into developers mode
5. Have selected MTP on developer options
6. Nothing shows up in device manager
Have you tried with another PC?
Any notification on the Shield, that it has been connected by USB? And if so, select MTP (selecting MTP in Developer's Options doesn't always work on some devices).
You tried other USB ports on the PC? You said you tried another cable and "connector", so maybe by "connector" you mean the USB port on the PC? Also, don't use a hub, connect directly to the USB port on the PC.
If none of this work, and never did on this 2nd hands device, you may have a damaged USB port on the Shield.
Try going to Developer options - Revoke USB debugging authorizations. That has worked for me in the past. I would doing it with the USB disconnected then reconnect.
I think I'm doing something wrong, the Pixel 2 only works with certain cables, or something else (port defect, OS defect, special drivers needed, etc.). I wanted to transfer some files from my PC (Windows 10) to my phone. I have a USB 2.0 to type-C cable that I plugged in. The phone came up in Windows but the contents of the window were blank. I could not access any contents or view anything on the phone. In Settings under USB I saw it said "charging" so I selected "transfer files" and it disconnected from Windows and reconnected only to go right back to charging. I have locked/unlocked, restarted the phone, tried different USB ports, and nothing works. The only function that works is "charging." When I use the supplied type-C to type-C that came with the phone I can get it to work only if I plug into the computer, then the phone, lock the phone, and then unlock it using my PIN (not fingerprint). I ordered a USB 3.0 to type-C cable to see if that works. Is there something I'm missing on why the phone won't connect with a USB-A to USB type-C cable...except to charge? Drivers or something else?
Also...I've reset the phone once (that didn't work either)...and even tried enabling USB debugging.
Please help. Thanks in advance.
Well...I think I figured it out with more troubleshooting. Apparently, you can't connect this phone to a computer via a USB hub. I was able to get it to work by plugging directly into my computer. I tried it on two different powered USB 3.0 hubs and it didn't work. Not sure why or if there is a way around it for convenience.
Hi,
Thank you for the forum (first post).
Trying to get the S6 recognised by pc:
When the phone is connected to the laptops usb port via micro usb and cable (usb debugging on, samsung usb drivers downloaded, mtp:usb on) the computer makes the 'plugged in' audio sound but there is no 'permission to transfer files via usb' type message.
It does charge.
Does this maybe mean the charging port is broken/damaged, or the usb is broken?
Only other detail is that I once got the computer to say in a pop up that it was labelled as a 'samsung s6' rather than unknown device, which it normally does. This any symptom maybe its just a software issue?
Trying to get my computer to connect to the phone and have tried most if not all software solutions so far (including factory reset) and now looking if its hardware. Any tips to get it connected welcome.
Thank you,
David
