I think a better place for this would be in usbnet_probe() (together with all the other dev->xxx initialization).
Definitely better.

I'm not quite sure how that could cause the transfer problems you are seeing, but at least you will no longer initialize the waitqueue multiple times on multiple usbnet_open (which is probably a bad idea).
Yeah, I agree. I don't expect usbnet_open would get called multiple times but I'll try the above anyway. thanks, grant -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
