I would like to transfer data from a USB Host (of my Laptop or Android Device) to Serial COM port (of a Desktop PC) through a USB - Serial port(DB-9) adapter.
Is there any library existed to do this task??
i have already studied and tried http://developer.android.com/guide/topics/connectivity/usb/host.html but failed.
Can i send data by a using a java program or Android App from my Laptop or Android Device ??
Can i receive data by an app in Desktop PC and show us????
If so please guide me how.
