I don't speak/read english very good, sorry. The macro that work good for us , from kernel 2.4.20 and change in 2.4.21-pre5, is: #define usb_settoggle(dev, ep, out, bit) ((dev)->toggle[out] = ((dev)->toggle[out] & ~(1 << ep)) | ((bit) << ep)) The expansion for "usb_settoggle(ps->dev, ep & 0xf, !(ep & USB_DIR_IN), 0" is : (dev)->toggle[!(ep & USB_DIR_IN)] = ((dev)->toggle[!(ep & USB_DIR_IN)] & ~(1 << ep & 0xf)) | ((0) << ep & 0xf) You say "> It looks like the macro version of usb_settoggle() is correct." but "the 0 value is what the result should be" too. But macro version get 0x20 not 0x00. Function version get 0x00. ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
