Interesting USB power measurement devices. Russell, thank you for the suggestion and links.
(1) what range of kernels does the wifi dongle work with? Or Debian distros, or other measure of "drivers reaching into the past and future?" (2) The power indicator displays on the side (and probably displays nothing if the wifi ports it plugs into are all unpowered). Is the power information also accessible via the computer USB port itself, and/or the USB devices (or USB hubs) downstream? Beyond some limit, "Universal Serial Bus" is only "mostly universal." FYI: Amusingly, when I use a Prime account to search the Amazon Pluggable page for "USB C Power Meter Tester", I get four hits; Two seemingly identically-described devices: ... one delivered on Monday for $22.95. UPC 819927012788 ... the other delivered on Tuesday for $25.46. UPC 819927011415 Amusing. The Amazon Prime search also regurgitates: An extension cable with a power display on the cable socket end for $25.16 USBC-METER3-1MF A "Power Strip" (actually a cube with 5 ft power cord) , PS3-METERC3 . Display, AC cord, 3 AC outlets, and 3 USB C sockets) for $64.95 UPC 819927013419 . Thanks for the pointers. If/when a remotely-readable version appears, I'll buy some. I'd also like to purchase a similar-form-factor device that counts USB packets and/or bytes. Keith Lofstrom he/him/obnoxiousbastard kei...@keithl.com
