This should be named _open_device_async_cb()

SPICE_USBREDIR_CHANNEL(object) would be better than the direct cast.

I don't think you need this _ref() here,
g_simple_async_result_new(channel, ...) will take a reference for you
for as long as the GSimpleAsyncResult object is alive.

All the changes below in usb-device-manager.c seems to be more or less
unrelated to the changes above, and aimed at setting 'redirecting' to
TRUE/FALSE when redirection starts/ends, I suspect it would be clearer
to do this in a separate commit.

Can't this be done in spice_usb_device_manager_channel_connect_cb()
rather than introducing an extra async_cb step?
