Hi all,

I've got an issue with the iMX53QSB board and any 2.6.38 kernel that is claimed to support it. The issue is with USB host controller. I have only one mouse connected to the upper port. The last kernel I tried is the release https://launchpad.net/linaro-landing-team-freescale/trunk/2011.09

Here's what the log is:

Does anybody know any cure for that?

 

Thanks!
