Did you read my post, or just the subject? I’m not asking for help, just sharing an observation - just in case I got a bunch of "me too"s.

I resolved my issue by unplugging and replugging my Zooz USB stick.

It seemed to be a hardware issue - the blue light on the controller was out until I removed and replaced it. It’s too much of a coincidence for me though that I just happened to have this hardware issue at the time when the software that uses that hardware was being updated.

I use Vendor/Product ID to access it:

# lsusb
Bus 002 Device 005: ID 10c4:ea60 Silicon Labs CP210x UART Bridge
Bus 002 Device 004: ID 051d:0002 American Power Conversion Uninterruptible Power Supply
Bus 002 Device 006: ID 1a86:55d4 QinHeng Electronics 800 Z-Wave Stick

I feel that this battle is lost. Many of the cars that blind me are newer models with (presumably) the headlights they came from the factory with. Yes, the lifted redneck trucks with ill adjusted LED “bulbs” in reflectors that were made for halogens, are worse - but not a lot.

As long as design regulations allow it, they will build it. So, anyone wanting to do anything about this should focus their energy on lobbying their relevant government agency.

Maybe someone might invent night driving glasses that can filter the particularly annoying wavelengths.

yeah, I need a TPU - my CPU is 5 generations too old

but not really sure what you are doing?

I want to install one of these in a machine that doesn’t have an M.2 slot.
