Hello,

 

I am running 6.0-beta4 , does anyone know how to do a USB passthrough so that I can access a usb device in the Ubuntu Guest?

 

I tried updating my config file to the following :

 

name = "ubuntu"

bootloader = "pygrub"

#kernel = "/mnt/cache/VM/ubuntu/vmlinuz"

#ramdisk = "/mnt/cache/VM/ubuntu/initrd.gz"

memory = 2048

vcpus = '4'

disk = ['phy:/mnt/cache/VM/ubuntu/ubuntu.img,xvda,w',]

vif = [ 'mac=00:16:3e:aa:bb:cc,bridge=br0' ]

usb=1

usbdevice=[ 'host:0764:0501' ]

#extra = "debian-installer/exit/always_halt=true -- console=hvc0"

 

 

However when I xl console ubuntu , and do lsusb i get the following :

 

lsusb

unable to initialize libusb: -99

 

 

I get the same (using Tretflix vm)...

Try usb=0 :-)

Also, please upgrade to beta 5a.  Just replace bzroot, bzimage, readme, and xen in the root folder of your flash device and reboot.

Upgrading to 5a and usuing USB=0 didnt do a thing for me

 

I have, however, fixed it by passing through the pci adaptor:

 

In my go script (havent checked it works from coldboot but manually tested)

# pass through usb ports for node-red serial
xl pci-assignable-add 00:1a.0
xl pci-assignable-add 00:1a.1
xl pci-assignable-add 00:1a.2
xl pci-assignable-add 00:1a.7
# xl pci-assignable-list 
# tests that the adaptor is available for passthru, 
# test again after vm started to see that they are allocated

 

and my config:

name = "Tretflix"
bootloader = "pygrub"
memory = 3608
vcpus = 2
disk = [ 
   'file:/mnt/cache/domains/Tretflix/Tretflix-v1.3_x64-NAS-disk1.raw,xvda,w',
   ]
vif = [ 'mac=00:16:3e:01:01:02,bridge=br0' ]
bootloader = "pygrub"
pci=['00:1a.0','00:1a.1','00:1a.2','00:1a.7',]

You shouldn't have to pass through the entire bus for USB in order to get a single device, but to be fair, I haven't messed around with this inside a linux VM just yet.  Will look at this more in the weeks to come.

I had the same issue with USB devices and ended up getting an add-on USB3.0 controller to pass through to my Windows VM.
