Is there an intention to add the configuration for the USB host controller for Bamboo/Yosemite to the mainline kernel? drivers/usb/host contains ohci-ppc-soc.c/h, but the Kconfig isn't updated to include it for 440EP/EPx?
I noticed it is configured in the Denx 4.1 2.6.19.2 kernel. When I updated the 2.6.21 drivers/usb/host/Kconfig to include the controller support for 440EP for some reason I couldn't get the kernel to recognize the controller or devices when it boots - not sure if there is something else I am missing here? One thing I noticed was that in the 2.6.19.2 kernel CONFIG_USB_OHCI_BIG_ENDIAN gets defined - in 2.6.21 there is both CONFIG_USB_OHCI_BIG_ENDIAN_DESC and CONFIG_USB_OHCI_BIG_ENDIAN_MMIO - assume I want both defined? Wondering also if anyone has much experience using the USB interface on Bamboo - and if any reliability issues have been observed? I have a Bamboo system where we've added graphics card init capability to PIBS and are using the DENX 2.6.19.2 kernel and booting X (Xorg 7.1.1 - Debian 4.0 system on hard disk) with a USB keyboard and mouse - and sometimes the mouse/keyboard are not detected properly by either the kernel on boot, or by X during its initialization (sometimes even after the kernel seems to detect everything fine). I did play a bit with a memory stick on the interface and that seemed reliable for the little I did with it. I am using an Apple keyboard plugged into the USB port on the board, with an IBM Scrollpoint USB mouse plugged into one of the ports on the keyboard.

OK ... One typical fail scenario is that the keyboard/mouse seem to be detected fine by the kernel, but X doesn't start because it can't locate the mouse device (messages in /var/log/Xorg.0.log). I did find the following power down sequence which does seem to result in reliable detection/operation whenever stopping/starting the system: - Shutdown from X Desktop - When Linux console 'power down' message appears, (with power still on) unplug then plug the keyboard from/into the USB port - Power down the board - Turn the power supply off/on Thanks, Steve _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
