I am trying to emulate Raspberry Pi image on Linux host and have
access to host USB ports and failing
My basic command line is
qemu-system-arm \
-kernel qemu-rpi-kernel/kernel-qemu-4.4.34-jessie \
-cpu arm1176 \
-m 256 \
-M versatilepb \
-append "root=/dev/sda2 panic=1" \
-hda 2017-07-05-raspbian-jessie.img \
-usb \
-redir tcp:5022::22 \
-redir tcp:5080::80 \
-serial stdio \
-no-reboot
And I also tried to add some combinations of options such as
-usb \
-device qemu-xhci \
-device usb-ehci,id=ehci \
-device usb-host,hostbus=1,hostport=1.3
and so on, but failed.
I have no any usb on guest and also have
$ lsusb
unable to initalize libusb: -99
My host is Ubunto 18.04, my device is serial-based custom USB device
On host:
$ lsusb -t
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
|__ Port 6: Dev 2, If 0, Class=Mass Storage, Driver=usb-storage, 5000M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/12p, 480M
|__ Port 3: Dev 2, If 0, Class=Vendor Specific Class, Driver=ftdi_sio, 12M
last one is interested
How to investigate and fix?
