USB Device command line restart?

[goinsnoopin]

Is there a command that I can ssh into Unraid and execute to have it be the equivalent of unplugging and reinserting a USB Device?  

I am passing a USB zigbee coordinator cc2531 to my zigbee2mqtt docker.... everything works fine, however when the docker updates it does not start.  When I am home this is no big deal as I just unplug then replug the USB dongle then start the docker container....however sometimes I am away so I would love a command line way to do this.

 

Thanks,

Dan

+1, this is essential

 

apart from that, what are your experiences, are you happy with it?

I am planning to use it with Home Assistant and Mosquitto, each in a docker container. Does that work?

But, you would have to be very careful to not detach the boot flash drive, as then you'll run into other problems.

I followed the instructions here which works well via command line.

 

The usbfs interaction seems to have changed a number of times since this question was originally answered. So, here's how I cycle hub port power on Ubuntu Oneiric Ocelot from a Bash shell.

Search for the bus and device number:

sudo lsusb -v|less
Locate the device in the bus / hub port hierarchy using the bus and device number:

sudo lsusb -t|less
The syntax seems to be 'bus-port.port.port.port.port...' For example, my mouse is connected to an external hub which connects to my computer's hub which internally connects to a root hub:

/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/2p, 480M
    |__ Port 1: Dev 2, If 0, Class=hub, Driver=hub/6p, 480M
        |__ Port 1: Dev 3, If 0, Class=hub, Driver=hub/3p, 480M
            |__ Port 1: Dev 6, If 0, Class=HID, Driver=usbhid, 1.5M
So, '2-1.1.1' in the above case. Finally, cycle the port power:

echo '2-1.1.1'|sudo tee /sys/bus/usb/drivers/usb/unbind
sleep 1
echo '2-1.1.1'|sudo tee /sys/bus/usb/drivers/usb/bind

Is there a way to automate this to execute at reboot (or at restart of VM, or restart of OZWDaemon docker)?
