Dell XPS 8700 KVM

Finally got my Dell XPS 8700 running but I'm having issues using a KVM switch. The mouse and monitor work fine and it switches easily between my two computers. I've been having a problem with the keyboard though. It wasn't working at all at first unless it was plugged directly into the computer. I moved the KVM to from a USB 1.1 to a 2.0 and it started working to type in the password. Once past the password the keyboard just stops working again. Any ideas on what I can try?

MacOS Mojave 10.14.6
Dell XPS 8700
i7-4770 3.4Ghz
AMD RX460 2GB
Z87 Express Chipset
16GB DDR3
Thanks!
