so i have a neat usb cable tester now. two questions:
1) should i get a label maker and start labelling some cables with their stats where non-obvious
2) should i make a hall of shame of cables i have that are frankly silly or overtly evil (e.g. usb A to A cables, data only cables, cables with bizarrely high value resistance?)

@pikhq i have an entire drawer labeled "USB abominations".

There are so many weird perversions out there.

A-A is far from the worst.

What about a double ended C-C female coupler? Double A male to single A female? A male to 2.5/5.5mm barrel jack?

@pikhq or A to 8p8c? Not ethernet. D+ D- Vbus and ground crimped directly to 4 pins of an rj45

@azonenberg oh no, the other ones i was nodding along and going "yeah that sounds typical" but what the fuck

@pikhq that one was found at work i don't know what it was from. Guessing some piece of IT gear or an old customer project but who knows.

At home I have an ebay fpga board with a mini B connector that's pinned to a 3.3v uart, not usb protocol. I need to make a cursed adapter so i can talk to it

@azonenberg @pikhq I've dealt with micro-b pinned to 3.3v SWD

@azonenberg @pikhq 8p8c or 10p10c? The second one is what many APC UPSes shipped with.

@jernej__s @pikhq i didn't count the pins and assumed it was rj45 could have been 10 pin

@azonenberg @pikhq I have some terrible ones I've made, like "2.5/5.5 female to USB C male" and "Dual A male to Mini-B"

@artemist @pikhq the worst I've personally been responsible for is a 4 port hub with male mini B ports on the downstream interfaces.

The idea was to mate backplane style to four devices with female mini-B ports and not need cables in between
