I am trying to use functionfs with composite gadget support for CDC/RNDIS ethernet. For testing, i use the ffs-test tool on the gadget side and connect it to a PC host. For Linux host, usb0 works ok. But it seems on the Windows 7 host side, the USB RNDIS driver does not bind with the device. Is there any additional steps needed to make ffs composite device work with windows 7? Or this is a limitation on the windows side?
Have you taken a look at this message: <http://permalink.gmane.org/gmane.linux.usb.general/48777> Apparently, there are some issues with current .inf file distributed with the Linux kernel. Since I'm currently missing both hardware and Windows, I am yet to investigate it.
Also, if i have to resort to use ffs in pure configuration and g_ether as single function gadget. I would need to obtain the hotplug event when ffs is in use. Then i can switch kernel modules, e.g. from g_ffs to g_ether. Is it correct to say the hotplug events can only be obtained from ffs ep0 by reading ffs events? I don't think we are getting a uevent in this case.
Currently, ffs has no uevents. It should be fairly easy to add some if you really need them. I think ffs_data_open(), ffs_data_close(), ffs_data_clear() and ffs_data_reset() are functions that are most interesting. -- Best regards, _ _ .o. | Liege of Serenely Enlightened Majesty of o' \,=./ `o ..o | Computer Science, Michal "mina86" Nazarewicz (o o) ooo +-----<email/xmpp: mnazarewicz@xxxxxxxxxx>-----ooO--(_)--Ooo-- -- 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
