Has any more testing been done with this? We're running into a situation where the USB subsystem crashes in a beagleboard xM after running for a couple hours to a day. A USB camera is running continuously during this time. The error message typically something like: [ 2817.415710] hub

[PATCH 1/1] Fix sprz319 erratum 2.1

2012-02-20 Thread Richard Watts
There is an erratum in DM3730 which results in the EHCI USB PLL (DPLL5) not updating sufficiently frequently; this leads to USB PHY clock drift and once the clock has drifted far enough, the PHY's ULPI interface stops responding and USB drops out. This is manifested on a Beagle xM by having the
