I have a XPS 13, L322x. Windows 8. It has 2 USB ports. One of the ports works fine. The second port used to work fine too, but now it will only operate some devices, such as a mouse. Other devices won't work in the second port--specifically, a flash drive or a USB modem. These devices work in the first port. I tried diagnostics but they didn't help. Any suggestions?
I would suggest you to reinstall the BIOS and the chipset drivers on the system to check if it fixes the issue. Please enter your service tag # on the link below, then download the BIOS from BIOS section and chipset from chipset section onto the system and install it.
Please let me know if this helps.
Thank you for replying. I tried the link and entered my service tag, but I could not find "BIOS section" or anything that would allow me to download the BIOS. or install it.
