USB passthrough is not working

octopus2903 · Jan 14, 2018

Hello from a bloody beginner!

I have a container with ubuntu server and try to passthrough some USB devices.
Unfortunately it do not work.

The devices are connected via USB hub to my Intel Nuc.

On Proxmox host I have the following devices:

Code:

ZWAVE
root@proxmox:~# ls -la /dev/ttyACM*
crw-rw---- 1 root dialout 166, 0 Jan 13 11:55 /dev/ttyACM0
Bus 001 Device 020: ID 0658:0200 Sigma Designs, Inc.

Viessmann Optokoppler
crw-rw---- 1 root dialout 188, 0 Jan 13 12:01 /dev/ttyUSB0
Bus 001 Device 021: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

Lacrosse Jeelink
Bus 001 Device 022: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
crw-rw---- 1 root dialout 188, 1 Jan 13 12:03 /dev/ttyUSB1

mit Cul868 (Attention: This device is connected via LAN-USB-LAN connector (appr. 12 Meter Cat7)
Bus 001 Device 023: ID 03eb:204b Atmel Corp. LUFA USB to Serial Adapter Project
crw-rw---- 1 root dialout 166, 1 Jan 13 12:05 /dev/ttyACM1

mit OWL Strommesser
Bus 001 Device 025: ID 0fde:ca05 Oregon Scientific CM160
crw-rw---- 1 root dialout 188, 2 Jan 13 12:14 /dev/ttyUSB2

Now I added the devices via ALIAS to /etc/udev/rules.d/99-usb-serial.rules:

Code:

SUBSYSTEM=="tty", ATTRS{idVendor}=="0658", ATTRS{idProduct}=="0200", SYMLINK+="zwave"

SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="A900WVZZ", SYMLINK+="viessmann"

SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="AL01MZ4B", SYMLINK+="jeelink"

SUBSYSTEM=="tty", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="204b", SYMLINK+="cul"

SUBSYSTEM=="tty", ATTRS{idVendor}=="0fde", ATTRS{idProduct}=="ca05", ATTRS{serial}=="0077CF1A", SYMLINK+="owl160"

When I check in host via "ls -la /dev/" I get only 4 from 5 devices:

Code:

lrwxrwxrwx 1 root root 7 Jan 13 17:27 jeelink -> ttyUSB1 lrwxrwxrwx 1 root root 7 Jan 13 17:27 owl160 -> ttyUSB2 lrwxrwxrwx 1 root root 7 Jan 13 17:27 viessmann -> ttyUSB0 lrwxrwxrwx 1 root root 7 Jan 13 17:27 zwave -> ttyACM0

cul is missing. why?

Then I put all symlinks into
/etc/pve/lxc/100.conf:

Code:

arch: amd64

hostname: fhem-container

net0: name=eth0,bridge=vmbr0,gw=192.168.0.1,hwaddr=52:7E:2B:F2:EE:2A,ip=192.168.0.25/24,ip6=dhcp,type=veth

lxc.mount.entry = /dev/cul dev/cul none bind,optional,create=dir
lxc.mount.entry = /dev/owl160 dev/owl160 none bind,optional,create=dir

I restarted both: host and guest.
When I try to find the devices in the Container via
ls -la /dev/
there are no devices

When I do
lsusb
I can see my devices on guest system:

Code:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 8087:0a2b Intel Corp.

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

BUT, when I do
lsusb -vs 001:005
I get some information, beginning with an error message

Code:

Can you please help me to passthrough my 5 USB devices?

P.S. Are there no code tags in the forum? (ok, first issue is solved: I found the code tags ;-) )

Hi,

i connect to viessmann (vcontrold) without any problems.

In your lxc.conf use colon (doppelpunkt) instead of equal (=). And give other create mode a try.

Code:

lxc.cgroup.devices.allow: c 188:* rwm
lxc.mount.entry: /dev/viessmann dev/viessmann none bind,optional,create=file

Must write "doppelpunkt" because the colon in clinch create a smily

Hope its works.
