performance - Error in android program -

i using android 4.2.2 i.e. api 17 error comes call require api level 12(current min 8): android.hardware.usb.usbmanager#opendevice

public list<usbserialdriver> probe(final usbmanager manager, final usbdevice usbdevice)      {         if (!testifsupported(usbdevice, ftdiserialdriver.getsupporteddevices()))          {             return collections.emptylist();         }         final usbdeviceconnection connection = ***manager.opendevice(usbdevice)***;         if (connection == null)          {             return collections.emptylist();         }         final usbserialdriver driver = new ftdiserialdriver(usbdevice, connection);         return collections.singletonlist(driver);     } 

as stated here:

public usbdeviceconnection opendevice (usbdevice device)

added in api level 12 opens device can used send and *receive data using usbrequest.*

parameters device device open returns usbdeviceconnection, or null if open failed
