I have a KVM virtual machine running CentOS 7 on a host running Fedora 24. I have a usb-serial dongle (actually a RFID reader but that should really not matter) that is installed on the host. The host can see it after running:

sudo modprobe usbserial vendor=0x1325 product=0xc02a

I have access to /dev/ttyACM0 which is the device I need to talk to.

How do I can access to said device on the guest (CentOS 7) system?

Can you use virtual machine manager? I highly recommend it if you are using a GUI. From there you can click on the little lightbulb icon on the virtual machine and select wich usb devices that are connected to the fisical machine the VM gets to see. Also I found this article wich shows you how to redirect USB from the xml file here. I havn't tested it myself but i t looks legit. I hope this helps a little.
