I've got a brother HL-1440 printer with USB port connected to a redhat 
linux bos with a 2.4.18 kernel.

when i reboot the computer and the printer is in powersave mode, the 
printer is not detected by the usb subsystem.
insmod printer does not cause a scan of the usb bus. the only way to 
make the printer work is to
-  pus the reset button to wake the printer up
-  unplug the usb cable from the server or printer
-  plug the cable in the printer or server.

then the printer is detected and everything is fine.

but since unplugging the cables is cumbersone (move the computer or 
printer) the computer ius booted at least once a day (in the morning), 
but the printer is never tunred off (trhe powerswitch is not easily 
accessible) i would like to change the situation. isn't there something 
availbe in the USB protocoll like "wake up all devices on the bus" and 
if such a protocoll element exists, how can it be issued by a linux USB 
driver?
