Article Summary: This article provides information on "XPS 13 (L321x) USB 3.0 Ports Stop Working after Windows Update".
After Windows updates, the USB 3.0 ports on an XPS 13 (L321X) will stop working. It appears that there is a Fresco Logic xHCI Controller driver being pushed, and this causes the failure. The Fresco Logic website recommends only installing drivers from the OEM provider. This is due to the fact that the driver has to be based on the chipset of the system as well.
Make sure the A02 driver version XPS-L321X_Chipset_Driver_R9WKR_WN_220.127.116.11_A02.exe posted on the Dell website is the one being used, and that no updates are applied unless they come from Dell. The easiest solution is to do a driver rollback within the operating system if there has been an unplanned driver update.
If the choice for Windows Update Settings has been selected for "Install updates automatically", the problem may reoccur. It is best to choose an option like "Download updates but let me choose whether to install them" so that Windows updates will not be installed automatically.
