Gui Posted July 4, 2012 Share Posted July 4, 2012 Let's say I have a USB device, a USB light to be specific. Is it possible via AutoIt to either turn it on or off? Since just by plugging it in into the USB port it turns on, would you take control of the driver port and enable / disable it? First of course you'd have to locate the driver port, which as to my knowledge is possible using the DeviceAPI. Any other ideas/suggestions/methods I'll take, as long as it works! Thanks!

Kidney Posted July 4, 2012 Share Posted July 4, 2012 most USB flash drives work the same as a HDD. on a computer, the HDD doesnt actually control the LED that shows drive activity. its the motherboard that does. turnning off the LED on the USB drive would mean turning off the power to the drive which is as simple as disabling the port.

Gui Posted July 4, 2012 Author Share Posted July 4, 2012 So is it possible to disable a port via AutoIt? Or does the Device API UDF have the ability to do so? Link to comment Share on other sites More sharing options...
Kidney Posted July 4, 2012 Share Posted July 4, 2012 i wouldnt be surprised if AutoIT could but i dont know the function to do that. Link to comment Share on other sites More sharing options...
Gui Posted July 4, 2012 Author Share Posted July 4, 2012 I know what you mean ;p AutoIt is powerful and most people fail to realize that. Meh I'll check out the UDF (http://www.fallenstar.net/autoit/DeviceAPI.au3). Perhaps it can do it. I'm just unfamiliar with drivers period.

BrewManNH Posted July 4, 2012 Share Posted July 4, 2012 A light that is powered by the USB port is powered by the 5 volts that is always present on the port. I don't think there's any way to shut off that voltage to the port, there might be a way to power off the port but I wouldn't know of one myself. Some motherboards may not even allow it if the voltage comes directly from the power supply. If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.Give a programmer the correct code and he can do his work for a day.

I'd just like be able to control the ports and/or what's attached to it for future purposes. Thanks for your insight! Link to comment Share on other sites More sharing options...

The USB light has no circuitry to interprete any control signals sent over USB - it simply connects to the +5V and GND wire to sponge up power.From memory, UHCI host controllers can shut off power to ports, but thats something thats managed deep inside the code of an OS, not something thats available to programmers. ongoing projects:-firestorm: Largescale P2P Social NetworkCompleted Autoit Programs/Scripts: Variable Pickler | Networked Streaming Audio (in pure autoIT) | firenet p2p web messenger | Proxy Checker | Dynamic Execute() Code Generator | P2P UDF | Graph Theory Proof of Concept - Breadth First search Link to comment Share on other sites More sharing options...
John Posted July 5, 2012 Share Posted July 5, 2012 wraithdu wrote an example script that can safely eject a USB drives and such. Might be what you are looking for in most situations. Link to comment Share on other sites More sharing options...
