USB problem in 2.6.14.5

USB problem in 2.6.14.5

[janiszo]

Hi,
Are there any changes in kernel 2.6.14 against 2.6.11 with USB support? I compiled new kernel with the same options as in the old one and system cannot see USB devices now. There is no /proc/bus/usb folder at all, while during startup mesaages about usbcore/ohci/mass storage registering appear.
I'm, using kernel 2.6.14.5 with patch-2.6.14-omap2.

Hi,

If you are using a OSK5912 board, please read the thread "OSK5912 USB 
Port Problem" in this mailing list (November 2005) (I am not sure if the 
problem also exists for other boards). An additional patch is needed for 
kernel from 2.6.12 to 2.6.15 to get USB host working. Alternatively, you 
can disable the RESET_UNUSED_CLOCK feature.

This is the patch:

Best regards,

Yes, disabling RESET_UNUSED_CLOCK made USB working again.
Thanks. I missed these archive posts.
