Línea de trabajo

Start with the attached coredump.txt and usb-device-info.txt, then trace the USB passthrough path for handling duplicate bAlternateSetting entries with different wMaxPacketSize. Reproduce by starting a VM and passing through the Bluetooth dongle; the issue is resolved when passthrough no longer crashes with this device.

What happened?

The virtual machine crashes on turning on USB passthrough of Bluetooth dongle. The problem is only with specific dongle, and does not occur if other devices are passed through.

coredump.txt

The difference between this USB dongle (which causes crash) and other devices (which do not cause crash) is duplicate bAlternateSetting with different wMaxPacketSize. I am not sure that this is a cause of the crash, but who knows.

usb-device-info.txt

It does not matter which OS is a guest OS. The bug can be reproduced with any guest OS. Also, it does not matter which USB controller is selected in settings: ECHI or OCHI.

How can we reproduce this?
  • Start the VirtualBox
  • Start the Lubuntu virtual machine
  • Insert the dongle to the USB port
  • Start passthrough using the menu
Did you upload all of your necessary log files, screenshots, etc.?
  • Yes, I've uploaded all pertinent files to this issue.
