Hello,
I re-post my question from some days ago, as I got no reply..
Please let me know, if my question is unclear, or if I can do anything
to make answering it easier.
I appreciate your help.
Greetings,
Hendrik
Hello,
I'd like to pass throug two identical devices to my VM. (using libvirt,
guest is debian). For one device, it works like this:
<hostdev mode='subsystem' type='usb'>
<source>
<vendor id='0x4fa'/>
<product id='0x2490'/>
</source>
<boot order='2'/>
</hostdev>
But now, I have another device just like this one:
Bus 001 Device 007: ID 04fa:2490 Dallas Semiconductor DS1490F 2-in-1
Fob, 1-Wire adapter
Bus 001 Device 005: ID 04fa:2490 Dallas Semiconductor DS1490F 2-in-1
Fob, 1-Wire adapter
Unfortunately, only one of these two devices appears for the Guest, even
if I duplicate the above entry.
Now, there's this option to pass devices:
<address bus='0x06' device='0x02''/>
But the Bus/Device can/might change... Maybe this can be overcome by
udev (and maybe this is the default in ubuntu? can someone confirm?)
I have tried the latter syntax aswell. Here the log-file:
Code:
LC_ALL=C
PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin
QEMU_AUDIO_DRV=none /usr/bin/kvm -S -M pc -cpu qemu32 -enable-kvm -m 256
-smp 1 -name WG -uuid fd90f0d6-122c-992f-a399-4105ee30d6e3 -chardev
socket,id=monitor,path=/var/lib/libvirt/qemu/WG.monitor,server,nowait
-monitor chardev:monitor -boot c -drive
file=/var/lib/zentyal/machines/WG/WG-Test.qcow2,if=scsi,index=0,boot=on,format=qcow2
-net nic,macaddr=00:16:3e:5d:c7:9e,vlan=0,name=nic.0 -net
tap,fd=29,vlan=0,name=tap.0 -serial none -parallel none -usb -usbdevice
mouse -vnc 0.0.0.0:0,password -k de -vga cirrus -usbdevice
host:04fa:2490 -usbdevice host:04fa:2490
usb_create: no bus specified, using "usb.0" for "usb-host"
husb: open device 1.5
husb: config #1 need -1
husb: 1 interfaces claimed for configuration 1
husb: grabbed usb device 1.5
usb_create: no bus specified, using "usb.0" for "usb-host"
What's odd in this:
-usbdevice host:04fa:2490 -usbdevice host:04fa:2490
And this, although I had used the bus/device syntax...
So, what would you recommend?
Regards,
Hendrik
