On my HP 4530s, USB sometimes stops working. No device detected (tried with an usb key and my samsung smartphone).
It has been like this for months. When it stops, it does this for days or weeks. Then some day, it just happen to works again, for days or weeks. Then not. Then again. :-/ Couldn't find the pattern.
I tried upgrading all drivers, then using alternative versions, then various combinations
It used to work quite well last year, and I can't see what caused this.
I have 2 SSD drives instead of the one that originally shipped (and removed the CD drive), but I guess that isn't the problem.
Everything looks fine in Windows' Device Manager.
