agraham Expert Licensed User Longtime User Jun 18, 2013 #2 From those IDS I think you mean FT232R which is not an Android Accessory but is a slave mode UART adapter. The UsbSerial2 library should recognise that chip. Upvote 0

agraham Expert Licensed User Longtime User Jun 18, 2013 #4 According to the USB Host Controller Play Store entry for USB Host Controller "The application does not use the USB Host API". It would seem that for some reason the official Android USB Host API on your Android device is not recognising the FT232R and is not passing it to the application. If your device is running Android 3.1 or later check you have the file android.hardware.usb.host.xml in /system/etc/permissions as mentioned here http://www.b4x.com/forum/additional...03-usb-rs232-adaptor-driver-5.html#post121125 If that does not work then I am afraid I have no further suggestions.

Connect your device to computer. open cmd and write cd C:\Android\android-sdk\platform-tools //This my path. You must write your path. 1-adb pull /system/etc/permissions/tablet_core_hardware.xml //if phone handheld_core_hardware.xml 2-Update that file and create android.hardware.usb.host.xml as specified by This Link 3-adb push android.hardware.usb.host.xml /system/etc/permissions 4-adb push tablet_core_hardware.xml /system/etc/permissions //if phone handheld_core_hardware.xml 5-Reboot. if you get error like read only first write adb remount after that do this steps. I upload files. Attachments platform-tools.zip platform-tools.zip 2.5 KB · Views: 566 Upvote 0
