The onboard xHCI controller (C610/X99 series chipset) does support MSI,
# pciconf -l -BbcV xhci0@pci0:0:20:0
xhci0@pci0:0:20:0: class=0x0c0330 card=0x72708086 chip=0x8d318086
rev=0x05 hdr=0x00
bar [10] = type Memory, range 64, base 0xc6100000, size 65536, enabled
cap 01[70] = powerspec 2 supports D0 D3 current D0
cap 05[80] = MSI supports 8 messages, 64 bit enabled with 1 message
I will give this a try.
Thanks,
