suddenly it started giving me no notification any time i plug it into any PC. I've used different USB cables,turned on my USB debugging mode,restored the factory settings, updated the phone software. I don't know what else to do. I really need help here
Browse to your sdk on studio terminal and type adb devices and check if it shows.
If not try adb killall-server and adb start-server otherwise try updating usb driver for your phone
If you have a Samsung Phone, try installing Samsung Kies on your PC. That should include all drivers.

So after I'm done using adb on my Android device, do I just unplug the USB wire from the computer and restart my phone, or not?
There is no need to restart your phone.
Using ADB doesn't inherently change anything about your phone's configuration. Some test frameworks may do things like disable animations on the device, which you might have to reset manually in developer settings if the tests are interrupted partway through and it fails to restore the original settings. But generally, rebooting won't help.
You can simply unplug your phone when you're done using ADB.

I am using ubuntu 15.10 and android 4.0.4. I googled a lot how to reverse tether from ubuntu to android but couldn't find any reasonable answers. So how can i share my ethernet connection on my ubuntu to android? i know i should create a new wifi hotspot from my pc and set it to "shared to other devices" but the wifi hotspot is NOT visible in my android phone! Also creating a wireless network with setting "infrastructure" to "ap" mode did not work for me.
Thank you for your answers!
Checkout hostapd.
This documentation for Ubuntu looks like it'd get you going, but you'll probably have to make a few tweaks, like wlan0 will be eth0. wlan1 would be the wireless adapter that is broadcasting to your phone.

When I connect my phone running android version 4.2.2 through the usb port the android phone driver is not installed. What could be the issue? I have searched a lot but could not find a solution.
Any insights would be greatly appreciated.
EDIT:
Usb debugging is enabled.
Phone Model and Make: Huawei 3c Honor (Just in case)
Update:
Question that may also be related or helpful but without answer given to my question: Installing the Android USB Driver in Windows 7
On windows you can just go to your device manager, click the unknown android device and install the driver which you can find in the follow directory. You have to pick it manually as scanning the directory for matching device drivers will show an empty list of compatible drivers.
<path to your android sdk directory>\extras\google\usb_driver
Is your phone showing the USB debuggging connected mode? Otherwise you might have to enable this in the developers settings.

after I rooted a Nexus 10 the app I have written which connects to an Arduino in USB Host mode no longer works properly. I'm pretty sure this is because the USB Host mode is no longer available.
I have checked the original unrooted device with Chainfire's 'USB Host Diagnostics' tool and it recognises the plugged in Arduino whilst scanning for connected devices, but nothing is detected after rooting.
Originally the device had Android 4.3 - build JWR66Y, and USB Host mode worked.
I rooted via the Nexus Root Toolkit and installed a rooted image of the same build, now the device isn't detected.
Any ideas what could be causing this?
Thanks
This is not a question of your app not working. I have seen it plenty of times that when someone roots a device the USB host no longer works. Its a problem with the ROM or method that was used to root the device. Best bet is to reset the device and try something else.
