As per [1] issue #4, "The periodic EP scheduler always tries to schedule the EPs that have large intervals (interval equal to or greater than 128 microframes) into different microframes. So it maintains an internal counter and increments for each large interval EP added. When the counter is greater than 128, the scheduler rejects the new EP. So when the hub re-enumerated 128 times, it trigged this condition."
Triggered.
This results in Bandwidth error when devices with periodic endpoints (ISO/INT) having bInterval > 7 are plugged an unplugged several times on a TUSB73x0 xhci host. Workaround this issue by limiting the bInterval to 7 (i.e. interval to 6) for High-speed or faster periodic endpoints.
