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.
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.
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.

Thanks for the useful report and data -- I think I know where the problem is and how to fix this.

Can you please elaborate further what exact kind this device is, e.g. manufacturer / exact model number or links where you got this from?
Also, was this 7.2.18 build installed directly from virtualbox.org, or was this a SuSE-provided package? If so, which one exactly?

It is a Bluetooth dongle. It was sold out, so the link is not available anymore.
Virtualbox was installed from openSuse repo.
