[Qemu-devel] [PATCH] Fix usage of USB_DEV_FLAG_IS_HOST flag.

[Qemu-devel] [PATCH] Fix usage of USB_DEV_FLAG_IS_HOST flag.

[Michael Marineau]

USB_DEV_FLAG_IS_HOST is the bit number, not value. Booting with a
"Fitbit Base Station" USB dongle was triggering this assert.

Looks good.

Anthony?  Can you pick it for 1.5 directly?  I don't have any other
pending usb bits for 1.5 at the moment.

Ping, looks like this hasn't managed to land in master yet and just wanted
to make sure it doesn't get forgotten. I probably should have noted in the
original email that this bug was introduced
in be41efde3ca0372dbf7543e09ff473b4eec25057 and impacts both 1.4 and 1.5.

Damn, missed 1.5.  Added to usb patch queue now.
Will also queue up for stable (aka 1.5.1).
