XHCI on Parallels VM

Mon Apr 7 05:14:14 UTC 2014

Hi,
I am developing a USB3 device based on the Cypress FX3 for use on FreeBSD (9 or 10) but my main development platform is OSX so I am running FreeBSD inside Parallels.

I find that if I enable USB3 mode then the device fails to enumerate with..

(I set hw.usb.xhci.debug=3)

This is with the USB UART sample code from Cypress (so I don't believe it's a problem with the code in the FX3 micro)

If I connect it with the boot loader running it works, however that enumerates as USB2, not 3.

I tried setting hw.usb.ehci.iaadbug=1, hw.usb.ehci.lostintrbug=1, hw.usb.xhci.use_polling=1 with no change.

I also tried setting hw.usb.xhci.xhci_port_route=-1 in /boot/loader.conf with no change (not that I expected it to since it emulates an NEC XHCI controller..)

Here is the output of pciconf -lv if it helps..
