Peter: Are there any known errata for the root-hub Transaction Translator in the Freescale host controllers?
When debugging some problems in an i.MX51 system, I found that the host controller would never issue more than 4 full-speed isochronous packets in any frame, no matter how many siTDs were linked into the EHCI schedule. Sometimes it would issue only 1 or 2 packets, even though eight were in the schedule! The behavior was very erratic. The controller seemed to work okay when the full-speed devices were behind a high-speed hub. The problems came up only when the host controller was connected to a full-speed hub.
