How many watt or amp is the usb ports on series x?

Xbox One accessories and peripherals will be compatible with Xbox Series X. As to whether the rechargeable battery packs are compatible with an Xbox Series X controller, that has not yet been revealed at this time, to my knowledge. However, the new controller
will use USB-C for its charging port instead of the Play & Charge Kit's Micro-USB plug.

Yes mate the Xbox Series X will have an optical out port, 2 HDMI ports, 2 USB-C port, Ethernet

Good evening

Ensure that you are using the correct USB port on your Series X. Some consoles have multiple USB ports, but not all of them may support USB 3.0 speeds. Check your Series X's manual or support website to see which ports support USB 3.0 speeds.

Try connecting the SSD enclosure to a different USB port on your Series X. If the first port you tried did not work, it is possible that there is an issue with that specific port. Try a different one to see if it recognizes the SSD enclosure as USB 3.0.

Verify that the USB cable you are using is rated for USB 3.0 speeds. Some USB cables may not be rated for USB 3.0 speeds and can cause the device to not be recognized as USB 3.0. Ensure that the USB cable you are using is rated for USB 3.0 speeds and is in good condition.

Why would you use a hub you said it yourself in your post

You are using more then one thing on your hub the WIRED controller is drawing powrr

You didntnanswer the question

Is it.powered.hub or just plain usb only

That's drawing power amytime you attach anything in the hub you are drawing both bandwidth and power away

You aren't getting what is going on

USB outputs so much power depending on the port

Pc depends on the cable grade ore port

Stick a hub into a USB 2 5 watt port will only draw 5 qatt

Stick it into 15 watt port

You can use upto 3 devices

Your whole.reason for using the hub is using the wired controller and.usb drive which is drawing power that's NOT one device

Here is articles about powered and non powered https://gamefaqs.gamespot.com/boards/264564-xbox-series-x/79305367

Yes. USB hubs will work. Just be careful about device power. USB power is spread thin unless the hub has its own power supply.
Things like hard drives consume more power, so make sure they are either straight connected to the system, or through a powered USB

No, I play the videos on an XBox Series X with the media player. The external SDD is connected via USB to the front USB port. There is no PC involved.
