Hey Nico, So I've been seeing USB issues on my beagle xm board with the latest linaro-2.6.38 tree, where when the system boots, lsusb will only show the hubs, but no devices.
Andy reported seeing similar on his overo board, so I bisected the issue down to:
9e64bb1e9f0613093b3e34ac5402fcfef0dcc35a is the first bad commit commit 9e64bb1e9f0613093b3e34ac5402fcfef0dcc35a Author: Keshava Munegowda keshava_mgowda@ti.com Date: Tue Mar 1 20:08:19 2011 +0530
arm: omap: usb: Invoke usbhs core device initialization
The usbhs intialization is invoked by all omap3 and omap4 variant board files.

It looks like this patch is just converting the initialization over to usbhs, so it doesn't really point out the specific issue, but it does seem that something in the usbhs core isn't working properly.
Any tips here?
thanks -john

Hmmm... Do you have the same problem with 2.6.39-rc1? If no then the linaro tree might be missing something that is present in mainline.

Actually I saw this same issue on my xM on mainline 2.6.39-rc1 yesterday.. It was strange since the ehci was working just fine on my omap4/panda with the same issue.. I know it was working on 2.6.38-git18 before the rc1 release, was going to bisect it tomorrow..

Yep. I see the same as what Robert reported. 2.6.39-rc1 is affected as well.

This commit appears to be the root of my problem as well.
Is there a bug tracking this? if not, would you mind opening one?
I fear this affects OMAP4 with the -omap flavor as well.
