Can't connect s2 to pc. Not recognized - Galaxy S II Q&A, Help & Troubleshooting

Hi,
My s2 is not recognized by my pc. I have the right software on my pc because my s6 is recognized fine. What could have caused this? What can I try?

If you have all the current Samsung USB drivers correctly installed, it is *possibly* due to the usb port on the phone beginning to wear out (it does frequently happen).
Have you noticed any other odd device behaviour?
Things like car mode suddenly being enabled for no apparent reason?
The phone showing it's connected to the charger when it isn't? Or not charging/not showing it's connected when it is?
Edit.....have you tried other USB cables?

[Q] Just got Tab back from Newton Ring screen replacement, having USB issues

None of my computers seem to recognize when I plug my tablet in while in Download mode, and while my desktop seems to activate the appropriate MTP notification when the tab is plugged in during normal use, my laptop just starts charging it, and doesn't even seem to recognize the thing.
Neither of my computers even make a noise to signify I've plugged something in when plugging in in Download mode.

Help USB problem

Just got a Galaxy S3 a few days ago, everything was going fine. Transferring music to my phone from my MacBook Pro using Android File Transfer. Half way through the app stops transferring and I have to force quit on my laptop. Now when I reattach my usb cable I get the following message: "No Android device found Please connect your Android device with a USB cable to get started" My cable is connected, my phone is charging, but the phone is not showing that it is connected (no usb in notifications, can't choose between MTP/PTP...) So I can't continue to transfer my music I restarted both my MacBook Pro and phone. I tried to see if its my phone by connecting to my dock in my car and everything works fine, my Car Home Ultra app opens and works fine. HELP please. How can I get my phone to recognize my cpu via USB? It was working fine, but now nothing other than charging. I read on another thread too toggle USB debugging in developer options, tried both to no avail. Help please, I am an Android noob.

USB keeps tab awake?

Hello there,
I plug in a USB to my Tab (p7510 , stock ICS 4.0.4) to listen to music located on my USB using the Samsung USB connector. After I unplug both usb and connector, I see under battery in settings that my device is constantly awake. Does anyone know the reason for this and how to solve it? Is it something to do with Mediaserver (it has a use detail of stay awake)?
Thank You
Michael

Problems with OTG connected USB devices

Ok, so has anyone else had problems with this..
when you plug in an OTG connected usb device (i have the same problem with usb drives and midi controllers so far) and in the notification bar pull down it will say charging usb device, and when you choose to switch it to something else, like transfer files or connect a midi device, it just goes right back to charging the device after changing it for a few seconds or until you tap the screen or check it again.
This has completely stopped me from being able to connect a midi device, and causes the usb drives to get hot, although I can still transfer files in an 3rd party file manager, but the notification bar will never stay in tranfer mode, and it has never gone into midi mode at all.
This is not an issue with my OTG adapter, as I also have the same problems with borrowed adapters, as well as using DEX. In fact in dex, if I plug in a usb drive and switch to transfer files mode it will crash. Has anyone else experienced these problems? Are any of these apps for OTG management in the play store useful for this? They seem to be useless based on the reviews except for testing a UTG adapter. Thanks!
btw I don't have root, my note 8 is fully updated to BQLA version.
Hi, check the battery! If internal resistance goes up so does noise.
Check the cable and connector on the phone as well.

S9+ not recognizing USB C Drive

I've been trying to find information about this on the web but I've failed to do so.
I bought a Kingston Micro duo USB C 3.0 and it worked a couple of times (I had to manually change to MTP) using the USB C connector straight on my S9+.
I've been trying to get it working again on my phone with no luck. Everytime I connect the USB C end on my phone, it will show on the notification tray "Usb charging device" and "USB connector connected", this last one will disappear in a matter of seconds.
I've set the default to be MTP using Developer Options and even select MTP for the device once it connects, but it just reverts its status.
I know for a fact the USB C end works because I can connect it to my computer (Windows and MacOS) and I've tried formatting it using a lot of different formats, still when I connect the USB C to the device it doesn't read it.
I managed to get the drive working using my USB C dongle (Which has 2 USB A 3.0, but no power passthrough) and connecting the USB A side to it and my phone recognized the drive instantly! So I formatted the drive using my phone, connected the USB C end on the device and it doesn't recognize it.
It seems it's just a bug on the Samsung device or something. I guess Samsung is moving towards USB C but they are not thinking on all the stuff you can connect.
I found this link https://us.community.samsung.com/t5...g-defaults-to-charge-other-device/td-p/183539 and this other https://forum.xda-developers.com/galaxy-note-8/help/note-8-usb-otg-t3680207 but so far no solution.
Edit:
I just tested my drive with an S8 and it worked without issues (the USB C end) and was able to test it on another S9's and they don't recognize it.
Mine works without issue. Not sure what's happening with yours sadly. Edit - mine's the Micro Duo 3C, but I can't imagine there'd be much difference.
Same here. Today I had hard times getting to work my USB stick and a default dongle. Every time I inserted the dongle the notification goes "USB charging device" and changing to "transfer files" doesn't change anything. Playing a bit made a 32gb stick visible in a file manager (namely x-plore) and I was able to transfer files to it. But no PC recognizes the stick so far...
