I have Samsung S4 Mini phone which I bought about 10 months ago. I used to transfer my files from phone to my PC and vice versa without any trouble using the USB cable. Recently, I enabled the Developer Settings (by tapping the build number 7 times), turned on USB debugging mode. I could transfer files even after this.
After a few days, my PC stopped recognizing the USB. I don't see the the USB button in the notification panel. I get a notification - "The last USB device you connected to this computer malfunctioned, and Windows does not recognize it".
In the device manager, I find Other Devices under which I see "Unknown Device". If I disconnect my phone, I don't see this entry.
I had searched quite a lot on Google for the same, but couldn't come up with a resolution. In fact, I did factory reset as my last attempt on my own and still couldn't find any result. (Lost all my apps for no reason).
Other Details: 1. I tried connecting my friend's phone onto my PC with the same cable, his device was recognized. 2. And yes, the cable was provided by Samsung itself, which used to work in the past and now it is not working.
Some one, please help me in connecting my phone to laptop using USB.
