The onboard xHCI controller (C610/X99 series chipset) does support MSI,
# pciconf -l -BbcV xhci0@pci0:
The controllers looks like this
# pciconf -l -BbcV ppt2@pci0:0:26:0
ppt2@pci0:0:26:0: class=0x0c0320 card=0x72708086 chip=0x8d2d8086

bar [10] = type Memory, range 32, base 0xc6134000, size 1024, enabled
