Hi David,

This bug depends on "Bug 1786413 - Assertion `dev->state == USB_STATE_DEFAULT' failed when setting spice usb redir during migration".

Verify this bug until Bug1786413 is fixed well, right? If not, I will verify this bug first, just focus on whether hit the new issue.

Many thanks.

Thank you, yes that's fine.

QEMU has been recently split into sub-components and as a one-time operation to avoid breakage of tools, we are setting the QEMU sub-component of this BZ to "General". Please review and change the sub-component if necessary the next time you review this BZ. Thanks
