Comment on Why is there no USB-C (female) to mini-B (male) adapter?

  How? Anything with a mini will be USB 2 at most and USB c defaults to lower power of USB 2 without any handshakes with the device which one with USB mini won’t do.

    Theoretically you could build a male to male contraption from multiple adapters and a cable. Also you could be providing too much current to a device, however this is specific to the combination of adapter, cable and power supply you use.

      You already can as these exist:

      letting you plug in any existing USB A to mini cables together to get a male to male device - nothing unsafe about that though. So this is not a very good reason to not allow USB C to mini adapters.

      Also you could be providing too much current to a device, however this is specific to the combination of adapter, cable and power supply you use.

      Current is pulled by the device - you cannot supply too much current. Devices take just as much current as they need or as much as the adapter can supply. The only way a device would take more than that is by badly designed or faulty - but that is a problem with the device, if the power supply can supply the power there is no issues on that side.

      Also USB C connectors can and do by default operate with USB 2 power - supplying 5V and limiting the current to the USB 2 standards and so any existing charger with USB A or mini connectors on. Thus any USB 2 device will only have access to the power given by the spec. You would require a handshake from newer USB protocols to get access to more voltage/current that some USB C chargers can supply.

      There is nothing unsafe about any other this baring faulty devices - but if we worried about faulty devices then we would not allow any electronics devices to exist as any of them could be faulty. USB C to USB mini does not dramatically increase any risk of fire or devices exploding no more so than any device using USB mini or USB C alone.

      The real reason is there is likely just not much of a market for them so they are harder to find - but they do exist.

  This will NOT cause a fire.

  Is it because USB C can be host AND device while Mini USB is only device?

      I’m not too sure, my reply was a question. I fail to see how it could cause a fire.

        Sorry, clicked reply on the wrong comment :)

  I’m not sure that there’d be enough voltage to cause a fire.
