Hello,
I use a desktop computer and I want to use a usb camera. During the first installation I was not able to create a usb-vm because I use a usb-keyboard.
Following this guide (USB qubes | Qubes OS)
I have done steps 1 to 7. My keyboard is on bus 005
[user@dom0 Desktop]$ lsusb | grep Keyboard
Bus 005 Device 002: ID 1a2c:002e China Resource Semico Co., Ltd USB Keyboard
the bus 005 has the id 0e:00.3
[user@dom0 Desktop]$ readlink /sys/bus/usb/devices/usb5
../../../devices/pci0000:00/0000:00:08.1/0000:0e:00.3/usb5
and the command line options look ok
[user@dom0 Desktop]$ cat /proc/cmdline
placeholder root=/dev/mapper/qubes_dom0-root ro rd.luks.uuid=luks-2213124b-01a3-4420-8086-33479998d66e rd.lvm.lv=qubes_dom0/root rd.lvm.lv=qubes_dom0/swap plymouth.ignore-serial-consoles rd.driver.pre=btrfs rhgb quiet usbcore.authorized_default=0 rd.qubes.dom0_usb=0e:00.3
How do I verify that the bus is attached to dom0 before I continue setting up sys-usb? I’m very afraid of locking myself.
I also checked
[user@dom0 Desktop]$ qvm-pci | grep 0e_00.3
dom0:0e_00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller
but there is no column USED BY which for comparison looks like this for an attached device.
dom0:05_00.0 Ethernet controller: Intel Corporation I211 Gigabit Network Connection sys-net
Thanks in advance!
