Huge Log FIles - usbconfig_user.log

Huge Log FIles - usbconfig_user.log

I am completely new to Desktop Central and have run into an issue.  3 of my workstations have almost run out of space on their hard disks due to an extremely huge logfile (usbconfig_user.log, 118GB, 283GB and 107GB).  The rest of the desktops have very small log files. What has caused these three to have such huge logs and how do I delete/fix them?
