Patch works when applied over commit 4f53138fff ! (bflags change and
it avoids the issue)

------
Maybe code changes on recent commits are interfering with the patch.
Same behavioral differences are replicated on QEMU using USB pass
through for this device: tested both 4f53138fff patched (OK) &
1613e604df0 patched (Not OK).
Thanks Bart.
