What ROM you running, that might help ..... maybe turn off ADB , in settings, and check usb storage there ...

no ROM, everything is stock and debugging mode is unchecked as well
when i mannually try to use the USB mass storage from Setting>Wireless>USB utillties and click on Connect Storage to PC it gives me a window saying "ATTENTION: Usb is connected. Remove the cable" when i remove the cable then it tell me to Connect the USB cable

Same thing happens to me.
My solution is to plug my/your phone to the computer and open the notifications. Click/press on the usb is connected notification and you can enter storage mode directly without hassle.

When I had this problem, I just needed to fix permissions in recovery. Is the phone rooted? Did you recently buy it new or used?

Solution is simple I suppose.
Disconnect the cable.
Go to settings from where USB connection can be enabled.
Click that option and it will ask you to connect the cable.
Only then connect it. That should be work.

Have you tried removing the battery, leaving it out a few minutes? After about 5 minutes reinsert battery and reboot device then try plugging up to usb. Also might try a different USB cord/charger ... whatever you're using to plug into whatever you're plugging into.

pc connection doesnt work

ok i was going to transfer some files to my phone via usb cable and when i connect the usb cable to the phone the only thing that happens is that it displays slow charging logo. i checked and the phone is set to ask what to do when the cable is connected and tried another cable. im not on a custom rom and i tried to factory reset the phone but still wont work. any ideas ?

Your problem seems simular to what I had.
If you are sure the software settings are ok and that doesnt work, remove the backcover remove the battery connector, put it back again and see if that works. Does charging work?

Thats weird my s2 tablet has USb problems to. It stopped reading OTG usb connections and the PC. However it is always able to charge. I have noticed that when it does finally read on the PC it seems like the drives dont switch right and my battery wont charge. It got to the point I dont even try to plug it into a pc or USB otg just incase it quits charging I have SD card and twrp for installs so I use that instead. Most be a problem with the usb port and drivers.

I dont know the answer nor the solution.
What I noticed however is that I used my tablet as an monitor for an USB web cam.
The problem (charging but not being able to connect to PC) started AFTER I removed the webcam.
The app I use (USB Camera Pro) has an option "remove camera safely"
If I use that option everything works fine but if I remove the cam cable without pressing this option I cant connect to my PC anymore and have to unplug the battery.

I am having a similar issue and would be grateful for help. My Tab T815 has a clean install of the latest Android 10 Rom and Pico Gapps via TWRP 3.4. All seem to be working great apart from the USB OTG. Specifically, I am trying to connect my DJI Mini drone controller and it's not registering it plugged in. I also have Android 10 on a galaxy S5 and have no issues at all when I connect the DJI controller to the phone. I have run a diagnostic app that says OTG is compatible with the T815 so am now at a loss on what to try next. Could this be an issue with the Rom?

Unable to connect device to PC

Has anyone had issues to have the phone recognized on a PC?
Previously i had been able to connect it and to flash regular updates with odin and out of the blue
the phone will not show up at all on the pc, it just charges and if i plug it turned off a warning sign shows on the usb connector.
Any ideas?
Thanks in advance.
