I forgot to mention that before testing with the VID 0000 Mouse, I had two xbox 360 controls connected and then I forcibly disconnected them. do not disassociate them

You need to add the script change into the qemu hooks file as per the first post.

With the VID Mouse connected, Can you provide me output of /usr/local/emhttp/state/usb.ini and lsusb.

@garydapogiEach VM has a limit on the number of Virtual USB ports, I think the default is 5. I think you can increase, not sure why it would have changed in 6.9.2.

You can sometimes clear by powering down VM and restarting. Not reboot has that doesnt release the virtual ports.

Also disconnects can sometimes leave devices connected and not freeing up ports..

This was the post for increasing ports.

You need to change USB type in template to

This will support 15 ports.

Hi @SimonF

I'm still experiencing similar error, keyboard gets disconnected randomly. Keeps happening on specific keyboard.

Should I increase the ports? -- (turned out it was already set to 15, which is the maximum)

I think they are already at the maximum.

When you get the error can you run virsh qemu-monitor-command "Windows 10" --hmp 'info usb' replacing Windows 10 with your VM Name i.e. Mintxxxx

You should get an output similar to below. Please can you post this output.

@garydapogiOk I can produce the error on my test machine.

I thought QEMU removed the device when it was disconnected from the host, but doesn't seem to be the case. Will add function to disconnect the device if udev detects a change.

Do you get this once the system wakes up from sleep? Can you provide an extract of your syslog after a wake up so I can see if there are any USB disconnects.

No, I get the error randomly, while using the VM.

I would like to connect a DVB-C USB stick plugged to a Raspberry Pi to the Plex Docker on the Unraid server to use Live TV & DVR from Plex directly.

Can this work and if so, how?

Yes it should work, But I cannot say how performant it will be.

Also USBIP has no security so should only be run on a local LAN.

If unraid is just going to be the client then you only need to have the vhci_hcd module loaded, Daemon and the usbip_host is only required if you want to attach Unraid connected devices to another host.

You will need to install the USBIP on the pi, there are screen prints of pi and unraid on the first page.

sudo apt-get install usbip

Once installed you need do

sudo modprobe usbip_host

sudo usbipd -D to start the Daemon.

Add remote host to in plugin.

sudo usbip list -l should provide you a list of devices

pi@raspberrypi:~ $ usbip list -l
 - busid 1-1 (0930:653e)
   Toshiba Corp. : Flash Memory (0930:653e)

sudo bind -b 1-1 this matches your device from the list above.

pi@raspberrypi:~ $ sudo usbip bind -b 1-1
usbip: info: bind device on busid 1-1: complete
pi@raspberrypi:~ $

Click attach

Device appears in your list of USB devices as if attach locally See Toshiba device at 003 002

I have released beta version of USB_Manager. USBIP-GUi and USB_Manager cannot co-exist and currently there is not an automated upgrade.

You can uninstall USBIP-GUI and Install USB_Manager. Note there is an addon for the USBIP support that needs to be installed.

You can copy the configs from usbip-guito the usb_manager as they are compatible.

Looking to get this up and running but getting the following error message "Following are missing or not loaded: USBIP Commands." from the above replies it seems that the "usbip-1 package" is not being installed for whatever reason?

I tried uninstalling both plug-ins, restarting unraid, etc however no luck. Any tips? I'm installing the latest "USB Manager (BETA)" from the App store and have not installed any versions of this plugin previously.

I can see the libvirt.img was created under a system share.

OK, let me check the checking for the command. if you run usbip from a command line do you see the following output. If you dont need USBIP at present you dont need to enable or install the additional package.

I have also had the following when installed:

Following are missing or not loaded: usbip_host module vhci_hcd module

When installed my config file looks like this:

<?php

$strXML = file_get_contents('php://stdin');

for ($i = 0; $i < $args->length; $i++){
	$arg_list = explode(',', $args->item($i)->nodeValue);

	if ($arg_list[0] !== 'vfio-pci') {
		continue;
	}

	foreach ($arg_list as $arg) {

		if ($keypair[0] == 'host' && !empty($keypair[1])) {
			vfio_bind($keypair[1]);
			break;
		}
	}
}

exit(0); // end of script
