This message is a continuation of my original problem. To this, I would like to add that the USB adapter does function on a WinXP setup. Thank you for the first reply. Now, the tablet at hand (Irulu 7? A008 WiFi only, of a 2012 origination date) is, nearly, of the latest model: Why would the Android USB API not be enabled (or am I mistaken here), if this is such a mainstream feature? The tablet does come with an OTG cable and will see a storage device, mouse, keyboard, etc. My worry is that, on the contrary, there are relatively few tablets that “fully” support the Android API for whatever reason (based on the USB host app output). May you give me examples of your statement that tablets support the proper USB API in the mainstream? I purchased the whole setup (tablet + ELM327 + Torque app) just for the purpose of using your app. If I understand your first reply, then will you ever add enhancement(if yes, then what is the timeframe..) to your software to see “rooted or third party” USB host API? There is an app (i.e., USB device info, etc.) that will see a connection on my device of the ELM327 adapter, but, of course, this app(s) does not do anything with the connection. I would simply like to know where the problem is and what your recommendation is to attempt to fix it.

AFAIK, there are only a few USB-serial chips that Torque supports right now. Which adapter do you have and which chipset is it using?

I think Prolific and FTDI are supported.

Torque has nothing to do with the “usb drivers”. That is up to your device. If your device cannot see the adapter, then that is your first problem. The ROM on the device needs to have support for the FTDI chip.

Once that support is there, torque will use it correctly.

The support is built into Torque, but your device needs to have proper USB Serial device support. Just because you have OTG for keyboard/mouse/Memory doesn’t mean a USB serial chip will work.

I just got the ELM 327 USB Interface and discovered the same USB non-connection problem with my Android tablet which does not have Bluetooth. There’s another thread that explains that the interface uses a CP 2102 chip rather than the FTDI chip and Ian doesn’t have the info to make a Torque compatible driver for the CP 2102.

My Elm works well with the Scantool.net app that came with the ELM, on a Win7 laptop, but the Torque app on a tablet is what I really wanted to run. There are custom PIDs for a Prius for the Torque app.

I guess my option is to get an Android tablet with Bluetooth and the ELM 327 bluetooth version or wait and see if Ian comes up with the CP2102 version.

On the other hand there’s a bunch of files with “FDTI” in their names on the little CD that came with the ELM. They may be all for windows but I’m going to look at them more closely.

Does your Tablet even support USB Host?

@frodus Yes

Mine arrived yesterday, unfortunately it turned out to be a prolific based adapter, not CP2102 so the quest to find one continues

Hi guys,
