[android-developers] Re: Any USB-Serial Adapter on Android Phones?

Thanks. I actually have done this already. Not always sure what to make of the info. When I plug in my Keyspan, I do see entries being reported in this app. I see them both under the Linux and Android tabs. In Android I see /dev/bus/usb/002/002 on my Note N7000. I see Interfaces 0 and 1 each with 4 Endpoints. Of the 4 endpoints, there are 2 called interrupt and 2 called bulk. I presume these are a set each for inbound and outbound. This device has only 1 serial port so not sure what there are 2 interfaces. On the Linux tab I see /sys/bus/usb/devices/2-1 and it is correctly identified by the app as a Keyspan USA-19H.

The thing that has me confused is trying to map all this only my experience on the Windows platform since I am an Android newbie. On Windows, these devices require the creation of a "virtual" serial port for a comm application to open. Is Linux/Android providing this automatically?

I would use something like the app "USB Device Info" (https://play.google.com/store/apps/details?id=aws.apps.usbDeviceEnumerator) to see if it is accessible via the USB host api (http://developer.android.com/guide/topics/connectivity/usb/host.html)...
