You can attach host device directly from virtual machines tab -> select VM
-> host devices sub tab -> "add device" button.

But first you need to verify your BIOS is supporting intel VT-d or AMD vi.
And you also need to activate it in the kernel. The next link describes how
to do it:

note: Instead of adding "intel_iommu=pt" in the grub cmdline, add
"intel_iommu=on" or "amd_iommu=on".

Another thing worth mentioning, USB hotplug is not supported yet, so if
your programmable device is resetting the USB connection each time you
program it, the USB will be detached from the VM and you will have to
attach it again in order to see it.
