[Q] USB Device Not Recognized [Unrooted]

Hello everyone,
My pc won't recognize my samsung galaxy note 10.1 GT-N8000 *4.1.2 Android version* and also on Kies
Already tried: -Reinstalling samsung device on PC
-Restarting the device (samsung galaxy note) as well as the PC
-Kies installed
PLEASE HELP!, I WOULD REALLY APPRECIATE YOUR REPLIES
BTW, here's the screenies ↓
Try a different usb cable... Sometimes it can be that...
Otherwise re-download the usb drivers and try that.. They can be found in dev section, a quick search will find them...
The problem is that u are using a hub port on your pc or a deffective one try another one and if you have another data cable to ensure that the problem from the pc and not the tablet

If changing the cable/port did not work try the following:
1. Bring up dial pad
2. Dial *#7284#
3. Select Qualcomm USB settings
4. Make sure MTP is selected, if it isnt, select it and click ok button
5. Reboot Phone

Samsung Galaxy S III Mini stuck on BOOTLOOP. Not recognized via USB on PC. No ODIN.

Hello. As the Title suggests, it is exactly my problem.
I have done quite a lot of research, and I have been able to find similar issues, but not the exact problem.
I tried installing an external source .apk and it resulted in crashing my Samsung Galaxy S3 Mini. Now the phone would simply restart and is forever stuck on the bootloop.
Now, the things that are working with the phone are:
Enter the Download (Odin) Mode (Volume Down + Home+ Power Button)
Things that are not working are:
- Unable to enter the Recovery Mode (Volume Up + Home + Power Button)
- Connecting to the PC, does not trigger any changes in both the PC and the phone. (There is nothing wrong with the USB drivers. I have installed the latest Samsung USB Drivers and tried connecting a different Samsung phone and it was detected on the PC as well as ODIN)
- As it is not detected in PC, the phone is not being detected in ODIN. The phone is connected in Download (ODIN) mode.
I don't know what to do at this point. Can someone please suggest some ways to fix this? Thank you so much!

When you connect the device to PC, does it show anything for the device in Windows device manager?

If nothing is showing in device manager, it could be a problem with the USB drivers, have you installed the "USB drivers for Samsung phones" manually or did you update drivers automatically using the "update driver" option in device manager?
Have you tried installing Samsung Kies? It will install the drivers correctly.
Have you tried the recovery options in Kies or SmartSwitch? One of them might be able to fix the device.
