bring back 3mm power jacks. Properly made ones are fine.
Most devices there is now no way to use data and charge at same time as the ye old laptop doesn't do the 1A to 2.5A wanted by the USB gadget.
Or HOW do you put USB keyboard (USB2Go host mode) and charge?
The ORIGINAL RUBBISH USB spec was root of problem.
1) It was purely Host - Slave
2) Not reversable in any sense
3) only 100mA, later 500mA
It should have been
negotiable up to 1A
Peer to peer
Negotiable higher speed
Same plug at both ends
Hermaphrodite (IBM token ring plugs), so socket and plug identical.
Totally different functions on same plug is disaster.
The SCART (apart from falling out) was only reliable as Stereo + Composite as they had separate pins for each direction.
Basic Signalling (two pins) was unidirectional
RGB was unidirectional
S-Video AKA Y/C an afterthought
Data signalling was non-standard and there was I2C as well as RS232.
I've noticed that HDMI isn't perfect, sometimes it's too fussy about which end is on first and connecting cables first, but it's better than this disaster called USB C
I have now THREE incompatible types of cables for laptop Host to gadget for USB. They are now adding a 4th!
Not only that but some USB gadgets (not even counting Apple's USB Optical drive that originally only the Apple thing could power) came with a Y cable to try and get enough power. No luck on that from some USB hosts / Hubs were the power available wasn't per socket but shared!
You'd have thought on the USB 1.1 iteration they would have sorted out USB.
