I’m trying to passthrough multiple USB devices to qemu-system-powerpc, a USB
keyboard and a USB mouse, from a linux host, however I can only get one to work
at a time, but not both.
Not real sure what the issue is, has anyone tried to passthrough more than one
USB device to qemu-systems-ppc?
Here is lsusb from the host
lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 413c:2113 Dell Computer Corp.
Bus 003 Device 002: ID 413c:3016 Dell Computer Corp. Optical 5-Button Wheel
Mouse
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 012: ID 05ac:828d Apple, Inc.
Bus 001 Device 004: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of
BCM2046 Bluetooth)
Bus 001 Device 005: ID 413c:2105 Dell Computer Corp. Model L100 Keyboard
Bus 001 Device 007: ID 413c:3016 Dell Computer Corp. Optical 5-Button Wheel
Mouse
Bus 001 Device 003: ID 04b4:6560 Cypress Semiconductor Corp. CY7C65640 USB-2.0
"TetraHub"
Bus 001 Device 002: ID 046d:c534 Logitech, Inc. Unifying Receiver
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
And this is how I’m trying to pass it to qemu:
-usb -device usb-host,hostbus=1,hostaddr=5 -device
usb-host,hostbus=1,hostaddr=7
I also tried to pass device 3 the USB hub and connect the KB/M to the hub, but
only one works, not both.
I also tried to pass device 2 a USB wireless Unifying Reciver for both a KB and
Mouse, but only the mouse works.
Anyone know what maybe going wrong here?
