qemu-system-arm and USB
 

Hello
I want to ask how i can make the guest shown from host as USB peripheral (not to use the hosts usb devices). I want to virtual plug my guest and lsusb on host to list it. Also i want to run adbd on guest and adb on host.
QEMU is 6.2 and OS is Slackware 15. I try with versatilepb and virtio machines.

QEMU already has host emulation, so should be able to support connecting your virtual device. Making it look like its an actual device to your host may require a driver on the host to create a virtual controller. When I looked around for such a beast I found https://sourceforge.net/projects/usb-vhci/ which seems to be an active project. I don't know what it would take to get it to talk to QEMU, though.

me too

I think one part of the problem is that the device tree doesn't mention the otg423 controller that why if i load the g_ether module dmesg says <<couldn't find an available UDC - added [g_ether] to list of pending drivers>>. Someone with more knowledge about? I will try the vexpress dts.
