Search: Catalyst 3850-48P-L Switch The driver is called Cisco_usbconsole_driver_3_1.zip Or the below URL if it is not stripped. https://software.cisco.com/download/home/284455380/type/282855122/release/3.1 To download the driver you will need a CISCO account login... update your account with your address... accept user agreement... apologies to coworkers for numerous expletives lodged during ridicules endeavor.
