Hi,

I have a PCIe USB card which is exported to the bhyve vm using
passthrough. I have tried to use the card in Ubuntu, Debian 8 and Centos
7. Each time the OS has given a segmentation fault on bootup and killed
the bhyve session. This is what i get in the bhyve-log:

The USB card works fine on the host and is detected by the xhci driver.
The card is "Inateck Superspeed 4 Ports PCI-E to USB 3.0 Expansion Card
- Interface USB 3.0 4-Port" (https://www.amazon.com/gp/product/B00B6ZCNGM)

ppt3@pci0:129:0:0:      class=0x0c0330 card=0x11001b73 chip=0x11001b73
rev=0x10 hdr=0x00
    vendor     = 'Fresco Logic'
    device     = 'FL1100 USB 3.0 Host Controller'
    class      = serial bus
    subclass   = USB

Any idea how can i use this card in a linux vm?


Thanks
