Well, for one thing the available full-speed bandwidth is less than 15 Mb/s. Periodic transfers (such as audio data) are not allowed to consume more than 90% of the total bandwidth. In addition, USB uses bit stuffing to prevent more than six 1's appea...

Not enough bandwidth for new device state. The bandwidth reservation is determined almost entirely by the controller's firmware with configure endpoint command. According to a software bandwidth checking formula used in Linux kernel (xhci_get_ss_bw_consumed(): (SS_OVERHEAD_BURST+mult*num_packets*...
