Thanks for the information, the problem you are facing is caused due to defective hardware of the computer, to be specific the problem is with the USB controller of the mother board, as it is also associted with the SSD, now can disconnect the SSD and let me know, what happens ?

Thanks for providing all the information and helping to understand the problem, but unfortunately I do not have any good news for you, because the problem you are facing is caused due to defective controller on the mother board and there is no other way to overcome this problem, without repairing or replacing the mother board. Please let me know, if you need any further help otherwise please remember to give positive rating, as that is the only way I am compensated for my time and effort.
