Most USB3 hubs with type-c captive cable don't have enough intelligence to handle CC advertising and work just fine - just tested a SSK SC-109 hub (mobile, based on latest VL822 controller) - it works just fine. And if a more intelligent "charging" hub is smarter, a simple 56k resitor(s) from CC to VBUS will likely satisfy its need. | |

That's why we don't have cords with mains plugs on both ends either. " - please don't use the slippery slope argument. If the adapters are so dangerous, all these producers would be sued to hell and go out of business. And why do you think that these adapters cannot be USB compliant? Many of them do have a CC controller with superspeed MUX inside. HP supplies one of these with nearly every USB4 dock. | |
| Oct 5, 2023 at 5:40 | comment | added | Justme | The question isn't if anyone likes them or not. They should not exist as per the standard, because they are dangerous, they allows you to accidentally connect two USB hosts or power supplies tohether, and that will do damage. That's why we don't have cords with mains plugs on both ends either. And what you propose by cutting off the upstream Type-C connector and replace it with Type-A, it does not work like that - you will be missing the negotiation pins of Type-C so it will render the hub useless. It will definitely not work with D+ and D- wires only. | |
| Oct 5, 2023 at 4:53 | comment | added | Ale..chenski | @Justme, yes, support for hubs in the car might be lacking, this is a very valid concern. But it should be easy to check with any old USB2 hub and a flash drive with MP3 music. And if you don't like the tiny c-2-A converter dongles, cut the upstream cable C connector and attach an ordinary Type-A plug with D+/D- wires only. | |
| Oct 5, 2023 at 4:42 | comment | added | Justme | I doubt it. Will the car allow a hub between phone? Also, this will require an adapter with Type-A plug to Type-C receptale. Such adapters are explicitly "not defined or allowed" by USB specification. As they should not exist and yet you appear to be able to buy those, I would definitely not suggest plugging dangerous and specifically forbidden adapters to an expensive-to-replace port of car multimedia system. | |
