The version of Linux kernel on the native host Fedora Core 5 machine is the default 2.6.9-1.667 kernel that comes with the FC5 release. Keeping in mind where we are, this does sound like an ancient kernel. However, I have USB networking with Gadget drivers working on this same machine with OMAP5912 OSK, OMAP2430 SDP and another custom OMAP2430 based board. Nevertheless, I decided to upgrade to a more recent version of the Linux kernel on the host system. I will test the setup once again and update the observation. Meanwhile, I tested the setup with a Windows XP host machine and these are the observations: On insertion of the USB cable to the Win XP host machine, the OMAP3EVM board gets detected as 'RNDIS/Ethernet' Device. I go through the driver installation (driver used is file Documentation/usb/linux.inf from the standard Linux kernel sources). After the installation is complete, I get an error from the Windows XP system saying "An error was encountered while installing the driver and the hardware might not function as intended" Thank you all, Regards, Kanagesh -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
