Dotaz: lxc a usb device

[jany2]

Proxmox VE 5.1-41
LXC debian 9 zo sablony
Mam cardreader s cipom FTDI 2232

lsusb
Bus 004 Device 002: ID 0403:6010 Future Technology Devices International, Ltd FT2232C Dual USB-UART/FIFO IC

dmesg
[   12.319214] usbserial: USB Serial support registered for FTDI USB Serial Device
[   12.319289] ftdi_sio 4-2:1.0: FTDI USB Serial Device converter detected

[   12.324021] usb 4-2: FTDI USB Serial Device converter now attached to ttyUSB1

Kedze v kontajnery som nemal /dev/ttyUSB0 a /dev/ttyUSB1, tak na hostitelskom jadre som vykonal

lxc-device add -n 101 /dev/ttyUSB0 /dev/ttyUSB0
lxc-device add -n 101 /dev/ttyUSB1 /dev/ttyUSB1

V kontajnery sa objavili teraz /dev/ttyUSB0 a /dev/ttyUSB1. Citacka ale stale nefunguje.
Do proxmax VE som teda skusil nahodit aj VM debian 9, ale na KVM a tam ta citacka funguje bez problemov.
Rad by som to ale rozbehal cez LXC, nie KVM, ale uz si neviem rady.
Vedel by niekto helpnut?
thx

Ten navodik som samozrejme nasiel pri googleni este pred tvojou odpovedou, ale nejak som tomu nerozumel. Skusim si to este raz poriadne pozret (teraz vsak bohuzial musim ist do sku****ej prace )

Este som nasiel tento navodik a aj som tak urobil, ale stale to akosi nemozem rozchodit.

root@proxmox:~# lsusb
Bus 004 Device 002: ID 0403:6010 Future Technology Devices International, Ltd FT2232C Dual USB-UART/FIFO IC
root@proxmox:~# ls -l /dev/bus/usb/004/002
crw-rw-r-- 1 root root 189, 385 Feb  6 09:57 /dev/bus/usb/004/002
root@proxmox:~# nano /etc/pve/nodes/proxmox/lxc/101.conf

a pridal som tam

lxc.cgroup.devices.allow: c 189:385 rwm
lxc.mount.entry: /dev/bus/usb/004/002 dev/bus/usb/004/002 none bind,optional,create=file

Asi sa na to vybodnem ... aj ked LXC je super, asi to budem uzivat len v PVE
