Does a USB OTG 3.0 cable exist?

I'm looking for a USB OTG cable to use with my Android devices, which will allow me to plug in USB devices such as flash drives,keyboard, mouse, etc. One end should be MicroUSB, which is the connector that most of my devices have. The other should be standard USB input. I know that a much slower USB OTG variant exists, but I think they all run at 2.0 speeds. Is there such a cable that is 3.0 capable? Does Android even recognize 3.0?

I've hunted around at local stores, they have USB OTG cables, but they all seem to be USB C, not MicroUSB. Apparently what I'm looking for is a specialty item that most big box retail outlets don't have, except maybe online. My local Best Buy also has flash drives that are MicroUSB on one end, but are USB output on the other, i.e. they can be plugged into something on that end but not the other way around. So it's essentially only usable as a flash drive, other drives can't be connected to it. I've also seen a photo of a device for the Google Pixel series, that plugs directly into the phone's charging port, which allows you to plug in a MicroSD, flash drive, etc. But I can't remember offhand what it's called, or if it's available in a MicroUSB variant. The Pixel is USB C anyway.

I had also read something before about a high priced USB OTG cable, apparently the only one of its' kind, called DECEC or something like that, which allows for charging and data transfer simultaneously. Every other USB OTG cable I've seen can only do one or the other at any given time. Any idea what it's called or if there is a similar product?

Thanks!

Edit: I only run custom firmware on my Android devices, like AOKP, LineageOS, CyanogenMod, etc, none of that bloated stock BS. All my devices are rooted running the latest Android versions, and usually have a custom kernel installed. I only mention this because I think what I'm asking for in the last paragraph, may only be possible with certain firmware/ROM and a kernel that is suitable to the task.

USB 2.0 or 3.0 depends mainly on the actual device (and its chipset).

 

IF the device has USB 3.0 chips, then the Android OS (at least the standard OS/firmware delivered with the device) will have the corresponding drivers (but the device will also have a different connector).

 

The USB OTG:

https://en.wikipedia...i/USB_On-The-Go

is a "standard" that is based on USB 2.0, though there is an "extension" for USB 3.0.

 

In other words, if your Android device is actually USB 3.0 capable it won't have a Micro-USB B receptacle (5 Pin), but rather a USB-C receptacle or a Superspeed Micro-USB (10 pin) receptacle, or , if you prefer, USB 3.0 needs 10 wires/pins.

 

See this:

Top right is the Superspeed Micro-B (10 pin) plug (USB 3.0) 

 

Here is an image of the receptacle (compatible with USB 2.0):

One "half" of the Superspeed Micro-B Receptacle will allow insertion of a normal Micro-B (USB 2.0) plug, see:

Well, most of the devices I have are up to 4 years old, the newest ones being a Huawei Honor 6X (MicroUSB), and a ZTE Axon 7 (USB C). The Honor is powered by a HiSilicon Kirin CPU, I believe the ZTE has a Qualcomm-based CPU. Some of the others are mostly Samsung, primarily a Note 4 (also Qualcomm). My future plans are probably going to buy the Pixel 2 128GB (USB C). I like to own multiple Android devices just so I can mess around, I don't really need them all, but it's nice to tinker and try different firmwares. And it rounds out my experience.

 

Are you saying that MicroUSB isn't capable of USB 3.0 speeds? The technology is just a bit too old?

Yes, exactly, simply the needed wires/pins are missing.

 

The "normal" USB (2.0) protocol needs 4 wires.

The "USB A" connector has 4 pins.

The "Micro-B USB" connector has 5 pins.

 

The "faster" USB 3.0 needs 9 wires.

The "Superspeed A" connector has 9 pins.

The "Superspeed Micro-B" connector has 10 pins.

Maybe it is easier if you check the matrix for cables/connectors here:

OK thanks for the info, I'll just buy a regular USB OTG 2.0 adapter, which is what 99% of sellers seem to be peddling.
