Hm, I get the following errors when trying to build the gadget drivers with this driver selected: drivers/usb/gadget/ether.c:260:9: #error Configure some USB peripheral controller driver! drivers/usb/gadget/ether.c:395: error: `DRIVER_VERSION_NUM' undeclared here (not in a function) drivers/usb/gadget/ether.c:395: error: initializer element is not constant drivers/usb/gadget/ether.c:395: error: (near initialization for `device_desc.bcdDevice') drivers/usb/gadget/ether.c:593: error: `EP_IN_NUM' undeclared here (not in a function) drivers/usb/gadget/ether.c:593: error: initializer element is not constant drivers/usb/gadget/ether.c:593: error: (near initialization for `fs_source_desc.bEndpointAddress') drivers/usb/gadget/ether.c:603: error: `EP_OUT_NUM' undeclared here (not in a function) drivers/usb/gadget/ether.c:603: error: initializer element is not constant drivers/usb/gadget/ether.c:603: error: (near initialization for `fs_sink_desc.bEndpointAddress') drivers/usb/gadget/ether.c:652: error: `EP_IN_NUM' undeclared here (not in a function) drivers/usb/gadget/ether.c:652: error: initializer element is not constant drivers/usb/gadget/ether.c:652: error: (near initialization for `hs_source_desc.bEndpointAddress') drivers/usb/gadget/ether.c:663: error: `EP_OUT_NUM' undeclared here (not in a function) drivers/usb/gadget/ether.c:663: error: initializer element is not constant drivers/usb/gadget/ether.c:663: error: (near initialization for `hs_sink_desc.bEndpointAddress') drivers/usb/gadget/ether.c:721: error: syntax error before "CHIP" drivers/usb/gadget/ether.c: In function `set_ether_config': drivers/usb/gadget/ether.c:786: error: `EP_IN_NAME' undeclared (first use in this function) drivers/usb/gadget/ether.c:786: error: (Each undeclared identifier is reported only once drivers/usb/gadget/ether.c:786: error: for each function it appears in.) drivers/usb/gadget/ether.c:794: error: `EP_OUT_NAME' undeclared (first use in this function) drivers/usb/gadget/ether.c: In function `eth_set_config': drivers/usb/gadget/ether.c:950: warning: implicit declaration of function `hw_optimize' drivers/usb/gadget/ether.c: In function `eth_ethtool_ioctl': drivers/usb/gadget/ether.c:1354: error: `CHIP' undeclared (first use in this function) drivers/usb/gadget/ether.c: In function `eth_bind': drivers/usb/gadget/ether.c:1860: error: syntax error before "CHIP" > By the way, is there any mechanism for adding dummy_hcd.c to your tree > while keeping all its associated BK history in gadget-2.6?

Yeah, the history will be lost, but no one really wants to see the whole development cycle of the driver :) I'll hold off applying this for now till the build fixes are done. thanks, greg k-h ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
