Would it be possible to add my own constant to /usr/include/linux/ usbdevice_fs.h and write an underlying function that would call usb_get_current_frame_number()? It looks like I can add a constant say USBDEVFS_FRAMENUM in usbdevice_fs.h, add new case to .../drivers/usb/core/devio.c, add a function called proc_framenum that would call usb_get_current_frame_number() and return the frame number. Is this a reasonable and/or feasible solution? ---- Danny Budik Research Engineer Inductive Signature Technologies, Inc. http://www.ist-traffic.com (865) 673-9434 ------------------------------------------------------------------------- Take Surveys.
