I bought an OBD ELM327 USB cable in order to use it with Torque Pro since Ice Cream Sandwich USB host capabilities and the Torque website claims that it works. The problem is that when I connect the OBD adapter to my tablet it simply doesnt do anything, but I expected the choose application window to pop up. I downloaded a usb device app and I can see that it is connected, but it doesn't recognize it. How can I configure it so when I connect it the choose app window pops up?

Just a cable? As for the choose-app dialog, it usually doesn't pop up if you have nothing to handle the event. Do you have an app that is supposed to work with this? – Matthew Read♦ Sep 17 '12 at 2:47
Its not really a cable, it is the OBDII ELM327 usb adapter.It is supposed to work with torque pro an app that specializes on car diagnostics via bluetooth and wifi but it also has the option to work with usb since ICS has the host capability.In the app's manual it says:Plug the usb and when the pop up window comes up for choosing an app to work with, check torque pro.I did this many times including when the engine was on but nothing happened.@MatthewRead – Chris Tsagarakis Sep 17 '12 at 21:09

You need a otg cable to put your android into hostmode, that is if your tablet offers usb otg mode. I have this setup running on my galaxy s2 and my daughters fuhu nabi 2 , works great except for I need better shielded cables to prevent ef interference freezing data.
