New usb device found

Keep getting this repeatedly in dmesg:

[ 205.654985] usb 1-1.3: SerialNumber: 00e04c000001

I assume this means not enough power and need to use a powered hub?

Device is this: https://www.amazon.co.uk/exec/obidos/AS ... os_product

This is what I would expect to see if there wasn't enough power...

I would try a powered hub and re-check...
