Re: omap 5912 linux 2.6.15rc2

[Jose Manuel Cano Garcia <jcgarcia@uma.es>]

Hi Rahul,

Please, read the thread "OSK5912 USB Port Problem" in this mailing list 
(its quite recent, November 2005). I successfully tried a 2.6.15 kernel, 
but I have to use a patch Tony Lindgren recommended me on that thread. 
The problem was something related to the reset of the USB clock at boot. 
This problem affects kernel 2.6.12 and beyond.  Other possibility is to 
disable the CONFIG_OMAP_RESET_CLOCKS option when compiling the kernel.

This is the patch:

http://linux.omap.com/pipermail/linux-omap-open-source/2005-August/004818.html 


Best regards,

Jose
