Jonathan Woithe reported that there was a regression for some older ch341 devices in 4.10. Turns out there were two of them. Jonathan, feel free to reply to this mail with a Tested-by tag. You've already tested these changes during development even if I've since split the patch in two. And thanks again for your careful testing while tracking this down.
