I think we have a LED subsystem already. Take a look at drivers/leds/ > Scan resolution -> The mouse lets you change the resolution (in DPI) > at which it scans the underground.

I agree, both of these should be standardized, and a simple sysfs file, with the same units for all devices, should be fine. > Firmware upload -> Not sure. Do we already have some generic device firmware > update API/subsystem? Yes, we already have a firmware interface within the kernel, that's been standard for a number of years now.

I agree, two of the above already are independant :) thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
