Dear all: I have ported my usb host driver on 2.6.25 but right now I have to change back to 2.6.18. I am wondering whether it is ok if I do the following steps: 1. replace header file located at include/linux/ in 2.6.18 with 2.6.25 2. replace the usb folder in 2.6.18/drivers with one in 2.6.25/drivers If there is something I need to pay attention, please let me know. Thanks for your help in advance, miloody -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
