Can Java application use USB Host on Android 2.2 device?

1.1k views Asked by At

I have Archos 101 Internet tablet which has USB host mode, but it's Android version is only 2.2.1 . As I read here http://developer.android.com/guide/topics/usb/index.html , Android has USB API from version 3.1 as well as in 2.3.4 . Is is there any way Java application to communicate through USB on such device with 2.2 ?

This might get you started in the right direction:

using serial port RS-232 in android?

It's likely you will need to get your hands on the kernel source which I believe Archos usually publishes shortly after a device hits the market. Grab the current config.gz off your device and figure out what kernel modules you may need and recompile. Good luck!
