What max current will the rear USB actually supply 5V at?

[Owen Smith]

I've never used gigabit Ethernet.

All the ethernet at my house is gigabit, except on links to things like HDR Fox T2 that support 100mbit max. I have 300mbit down / 50 mbit up broadband so I do get throughput greater than 100mbit on some operations, typically firmware updates of various things.

All the cabling in the walls and under the floor at my parents house is CAT 6 and within the length limit to be good for up to 10 gigabit, though they only have 100mbit on their router.

Question: Is there some kind of auto-detection which falls back to 10/100 (ie two pairs) if 1000 (four pairs) isn't working?

Absolutely, always has been. There is also now auto detection of which way round the pairs are so there is no longer any need for cross over cables, I remember needing those unless the hub or switch had a port labelled "uplink" sometimes with a switched for whether it was in crossover mode.

I was aware of that, otherwise my config diagrams above would have been far more complex! Even the HDR-FOX auto-detects, so it's not new technology.

So (jokes about milli-bits notwithstanding), running their AV over "economiser" shouldn't be an issue, if you can smuggle a switch into their setup at the router.

I forget when auto detect of cross over came in. It didn't exist 25 years ago last time I did some cabling in a commercial building.

Capitalisation is all over the place these days anyway. I lost the will to try to get it right when things like 7G started being used heavily instead of 7g to mean 7 gravities of acceleration. 7G is 7 times the universal gravitational constant, except apparently not anymore as I was told repeatedly somewhere so long ago I've forgotten where.
