In reply to Albert van Bemmelen.

Right! Albert,
Next-Generation USB PD 3.1 Extended Power Range increases maximum power from 100W to 240W (48V at 5A). To safely deliver 240W, specialized "EPR cables" and connectors are required that support 5A current and communicate with the charger to handle the higher voltage.

Thanks for sharing this now good cleaned and as new working fixed usb hub Yogesh.
Fixing usb hubs and new usb cables probably will get more complex in the near future because of the new QC and PD usb-C programmable power protocols that are introduced. With Fast universal charging & full feature USB-C ports that speed up the charging process in new USB-C devices.
