Hi, I have read various forum posts and some of the archive from this list about the following error message: Not enough host controller resources for new device state Some people have had success with disabling XHCI at the BIOS level. That seems to be an unnecessary work around to me given we are progressing towards USB4 in the not too distant future. Is there a definitive explanation other than "no one had time/resources to work on this issue yet" why we cannot have more than 30 odd devices connected with XHCI enabled? In my case I would like to use the full 128 ports on the USB bus. The gives me a practical limit of 100 mobile devices and 20 something ports for chaining usb hubs together. I am available to assist with debugging this issue if there is a way to make it work. -- Patrick Shirkey Boost Hardware Ltd -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
