A basic usb charging cable has 2 wires and a ground, usb 1.0 and 2.0 data cables have 4 wires plus a ground, usb 3.0 has 9 wires and uses a different protocol that allows parallel data transfer and greater power delivery. USB C can have up to 24 wires and obviously allows even greater power delivery and data speeds.
I was specifically talking about these antiquated mini usb (connector type) cables that ZOOM chose to use on a lot of devices including my h1 recorder.
My complaint about the 5 cables that I own is that while they are all mini usb and also, I believe all of them to be data cables as well (based on the devices that included them over the years), regardless of maker, even if no wires for data are present then the power delivery should still be consistent throughout.
So even though all of these are probably power+data cables, only one of them will deliver data or power to the zoom recorder which is always a headache figuring out which one because I don’t keep every item that I own in a specific little tupperware with the cable or whatever.
I just don’t understand why out of 5 of these antiquated mini-usb cables which are mostly from the era before they started making crazy internal differentiations and where any USB data cable had a max of 4 wires plus the ground that only one of them will power or connect the zoom recorder to the computer.
My whole point was that zoom products seem very picky about which cable you use even amongst what seem to be other identical cables, not just visually identical but functionally identical.
I hope that clears up the specific cable paradox to which I was complaining about earlier.
A lot of usb technology involves the host and the peripheral communicating and making requests and approvals. If there are 24 available connections in the fully featured usb c cable and it only connects 4 pins, then the computer knows that it’s only (at most) capable of that usb 2.0 protocol so it will negotiate power and data delivery based on that. If 24 pins are connected, then I assume the computer (if it’s usb c capable in the first place) starts the negotiation for power and data delivery based on that confirmation which is partially physical because it needs the extra pins to function in such a way.
When dealing with a host, the device itself requests a specific amount of power which is approved and then delivered. With charger type power supplies I think that it probably contains some kind of chip that the device gets information from, but that a lot of the power limiting is done with physical components internally.
As far as fast charging some cables may not be able to deliver as much power for the same reason, but some chargers (the wall unit itself) are limited in the amount of power that they can deliver.
My samsung tablet knows when it’s not connected to a fast charge source and says it isn’t able to charge at full strength every time I connect it to a power supply that is not it’s own or a comparable one, even using it’s own usb c to usb type A cable, which with the native charger does support fast charging.
It’s all a bad joke intended to get us to keep buying more cables. This absurd cable conundrum. Technology can go to hell.
