hi，

I have running Linux & Android guest OSes on IMX8qm board as <i.MX Virtualization User's Guide> desc.

But there is no input w/ usb mouse or keyboard plug-in the usb slot.

How to fix it?

Thank you.

Hello zfreeman2321,

Android and Linux is booting ok in the virtualization? The usage of external mouse trough USB should be in kernel configuration, or check if the mouse is present in /dev/usbX.

Regards

Hi,

Before booting or running the image check the USB it is available with:

Bitbake -c menuconfig linux-imx

Hi,

You are playing a kernel version that is not supported anymore, please upgrade to new kernel 5.10.52 BSP.

hi,

if upgrade to L5.10.52, must the Android version be 11?

hi,

Also I found that the 'imx-xen' project has not supported L5.10 kernel yet?

So, I think it could not be used in the virtualization build. Right?

That is correct!

"Android and Linux is booting ok in the virtualization? The usage of external mouse trough USB should be in kernel configuration, or check if the mouse is present in /dev/usbX."

In response, I checked that there is no device in /dev like /dev/usbX..

Hi,

What OS version are you using?
What hypervisor?

The "i.MX Virtualization User's Guide" seems to be a quite old document, please check instead "Chapter 12 Virtualization" in i.MX_Linux_Users_Guide. For Xen hypervisor there is an example of DomU configuration that contains USB configs.

Regards

hi,

I used L4.14.98 , android P and xen hypervisor as "i.MX Virtualization User's Guide" desc.

And using the default configs in source code tree

Hi,

I could not make Xen work on 4.14.98 but I have it running on 5.4.70 and the USB mouse and keyboard are working properly, even when plugged at runtime.
I have used default Xen configuration for Linux DomU /etc/xen/domu-imx8qm-mek.cfg.
So migrating to 5.4.70 should fix the issue.
