I have the following on the host machine
$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I would like second in a line device to be passed through to the machine.
Also
$ lsusb -t
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/12p, 480M
|__ Port 3: Dev 3, If 0, Class=Vendor Specific Class, Driver=ftdi_sio, 12M
What should I write in qemu command line? I wrote
-usb -hostbus=1 -hostport=3
and in failed to run with
qemu-system-arm: -hostbus=1: invalid option
I wrote
-usb \
-device usb-host,hostbus=1,hostport=3 \
And got
libusb: error [_get_usbfs_fd] libusb couldn't open USB device /dev/bus/usb/001/003: Permission denied
libusb: error [_get_usbfs_fd] libusb requires write access to USB device nodes.

errors during boot under conventional used. If ran under sudo I got no errors, but also got no USB working under quest.

Full command line

I have recompiled QEMU with
./configure --enable-libusb
but this didn't help. lsusb still gives an error. Also no rows about usb in dmesg. On real raspberri pi there are many usb rows including dwc_otg.
