Little explorations with HP calculators (no Prime)

[Zaphod]

rprosperi Wrote:My suggestion is to leave the miniUSB cables plugged-in to both calculators, and only plug/unplug the USB-A (PC side) connector as needed. The USB-A connectors are much more robust than the small and delicate mini-USB.

Apparently not....., the opposite in fact

USB-A has a mere 1500 mating cycle rating

See section 5.3 of this current example by molex

(same story with the A socket)

Mini-B is 5000 mating cycle rated

See section 4.2.2 of this active current example by molex:
https://www.molex.com/pdm_docs/ps/PS-51387-003-001.pdf

and Micro USB socket is 10,000 mating cycle durable

See section 3.3.2 on this active current example by molex again:

Goes against what you intuitively think based on the size of it, but there it is.
