I=E2=80=99m trying to access a Huawei USB LTE stick from a Bhyve VM like =
so:
# cat /var/vm/mgmt/mgmt.conf=20
loader=3D"bhyveload"
cpu=3D1
memory=3D256M
network0_type=3D"virtio-net"
network0_switch=3D"lan"
disk0_type=3D"virtio-blk"
disk0_name=3D"disk0"
disk0_dev=3D"sparse-zvol"
uuid=3D"53854567-8358-11e8-9638-000db94be2cc"
network0_mac=3D"58:9c:fc:04:1d:52"
bhyve_options=3D"-lcom2,/dev/cuaU0=E2=80=9C
On the host, I can connect ppp(8), but inside the VM, ppp(8) appears not =
to be able to talk to the USB device. Using cu(1), I can talk to it just =
fine though. I=E2=80=99m not sure how to debug this further. Is this =
supposed to just work, or am I missing some obvious configuration bit?
