What: /sys/module/ehci_hcd/drivers/.../uframe_periodic_maxDate: July 2011KernelVersion: 3.1Contact: Kirill Smelkov <kirr@mns.spb.ru>Description: Maximum time allowed for periodic transfers per microframe (μs)
Note: USB 2.0 sets maximum allowed time for periodic transfers per microframe to be 80%, that is 100 microseconds out of 125 microseconds (full microframe).
However there are cases, when 80% max isochronous bandwidth is too limiting. For example two video streams could require 110 microseconds of isochronous bandwidth per microframe to work together.
Through this setting it is possible to raise the limit so that the host controller would allow allocating more than 100 microseconds of periodic bandwidth per microframe.
Beware, non-standard modes are usually not thoroughly tested by hardware designers, and the hardware can malfunction when this setting differ from default 100.
