I have an HP Envy running FreeBSD 14.2.
I am a bhyve noob, but I am able to create a bhyve guest, and installed
freebsd 14.2 on it.
Here's my host pci devices:
xhci1@pci0:0:20:0: class=0x0c0330 rev=0x00 hdr=0x00 vendor=0x8086
device=0x06ed subvendor=0x103c subdevice=0x8767
vendor = 'Intel Corporation'
device = 'Comet Lake USB 3.1 xHCI Host Controller'
class = serial bus
subclass = USB
xhci0@pci0:1:0:0: class=0x0c0330 rev=0x00 hdr=0x00 vendor=0x1b21
device=0x3242 subvendor=0x1b21 subdevice=0x3242
vendor = 'ASMedia Technology Inc.'
device = 'ASM3242 USB 3.2 Host Controller'
class = serial bus
subclass = USB
Here's my usbconfig:
usbconfig
ugen1.1: <Intel XHCI root HUB> at usbus1, cfg=0 md=HOST spd=SUPER
(5.0Gbps) pwr=SAVE (0mA)
ugen0.1: <(0x1b21) XHCI root HUB> at usbus0, cfg=0 md=HOST spd=SUPER
(5.0Gbps) pwr=SAVE (0mA)
ugen0.2: <Hub Genesys Logic, Inc.> at usbus0, cfg=0 md=HOST spd=SUPER
(5.0Gbps) pwr=SAVE (0mA)
ugen1.2: <PixArt HP USB Optical Mouse> at usbus1, cfg=0 md=HOST spd=LOW
(1.5Mbps) pwr=ON (100mA)
ugen1.3: <Chicony HP USB Keyboard> at usbus1, cfg=0 md=HOST spd=LOW
(1.5Mbps) pwr=ON (100mA)
ugen1.4: <Realtek Bluetooth Radio> at usbus1, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=ON (500mA)
ugen0.3: <PNY USB 3.2.1 FD> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps)
pwr=ON (126mA)
ugen0.4: <Hub Genesys Logic, Inc.> at usbus0, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=SAVE (100mA)
Originally, my PNY flash drive was on usbus1, but when I added
pptdevs="0/20/0" to /boot/loader.conf, I lost my mouse and keyboard.
Fortunately, I recently added a pcie card supporting usb 20 gbps rates.
So I changed /boot/loader.conf to pptdevs="1/0/0"
But I don't know how to see the PNY flash drive in the guest. I was
hoping I could use gpart show -l and see a /dev/da0 or /dev/da1 drive,
but I don't.
In the guest, usbconfig:
usbconfig
No device match or lack of permissions.
and pciconf -v -l:
pciconf -v -l
hostb0@pci0:0:0:0: class=0x060000 rev=0x00 hdr=0x00 vendor=0x1275
device=0x1275 subvendor=0x0000 subdevice=0x0000
vendor = 'Network Appliance Corporation'
class = bridge
subclass = HOST-PCI
isab0@pci0:0:1:0: class=0x060100 rev=0x00 hdr=0x00 vendor=0x8086
device=0x7000 subvendor=0x0000 subdevice=0x0000
vendor = 'Intel Corporation'
device = '82371SB PIIX3 ISA [Natoma/Triton II]'
class = bridge
subclass = PCI-ISA
virtio_pci0@pci0:0:2:0: class=0x020000 rev=0x00 hdr=0x00 vendor=0x1af4
device=0x1000 subvendor=0x1af4 subdevice=0x0001
vendor = 'Red Hat, Inc.'
device = 'Virtio network device'
class = network
subclass = ethernet
virtio_pci1@pci0:0:3:0: class=0x010000 rev=0x00 hdr=0x00 vendor=0x1af4
device=0x1001 subvendor=0x1af4 subdevice=0x0002
vendor = 'Red Hat, Inc.'
device = 'Virtio block device'
class = mass storage
subclass = SCSI
How do I fix this?
