usb: PS3 EHCI QH read work-around PS3 EHCI HC errata fix 244. The SCC EHCI HC will not correctly perform QH reads that occur near or span a micro-frame boundry. This is due to a problem in the Nak Count Reload Control logic (EHCI Specification 1.0 Section 4.9.1). The work-around for this problem is for the HC driver to set I=1 (inactive) for QHs with H=1 (list head).
