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’m not a server admin., just a user. The Lemmy instance I’m on setup a Piefed instance in parallel and is giving users the option to use either, or both. I’m still trying to get my head around the history and the pros/cons of each but for now it seems like I’m switching to Piefed. I imagine that if most users move then the Lemmy instance might get shutdown in the future.

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.
