KWorld ATSC 330U

Making it work

This USB device sometimes does not enumerate, with dmesg showing e.g.:

usb 1-1-port6: Cannot enable. Maybe the USB cable is bad?
usb 1-1-port6: attempt power cycle
usb 1-1-port6: unable to enumerate USB device

Update: it appears this was a bad solder joint. It had quit working entirely, but after reflowing with a heat gun (260°C), it has been working perfectly again. Windows10 (both in-box drivers and those from the UB435-Q driver package) has choppy video (pixelates) and audio (echoes), but works very well in Linux.
