Re: rpi USB limited to 15 ports?

Thank you very much for the quick reply! Unfortunately I still get the same problem. I have used rpi_update following the instructions on https://github.com/Hexxeh/rpi-update and then added the text to commandline.txt in the boot directory so that commandline.txt now reads: dwc_otg.lpm_enable=0 cons...
