Modify Linux drivers for FPGA based MEI bill validator for use on Raspberry pi over USB

We are in need of an experienced developer to help us modify existing drivers based on Java to communicate with a FPGA based Bill validator from a Raspberry pi over USB. We previously modified existing java files to communicate with a bill validator that we later found out was using an old PSD based chip, whereas the new devices are based on FPGA chips. Our old code does not communicate with these newer devices and we need help modifying the drivers to enable them to communicate. We are using a raspberry pi (raspian) to control the device. Existing Java drivers for RedHat exist and may be useful to modify for the raspberry. I have included the below files that may be useful in completing this project. Linux [login to view URL]: These are the existing ReHat drivers [login to view URL]: Install guide for redhat drivers Linux Virtual COM Port (VCP) Driver [login to view URL]: Guide to modify drivers for virtual com port. 002850046_Series 2000 Interface Manual: Interface manual for bill validator. [login to view URL]: This is a folder including Javadocs, API, Demo, and source code as well as support files. [login to view URL]: Similar files to the [login to view URL] with some differences. My expertise does not allow me to verify which is newer or more useful so I included both. [login to view URL]: These are the files used to develop the Java doc that controlled the older bill validator. These may be useful in understanding what the end product may look like. Connection to the device will most likely need to be done over SSH as I have the devices connected to the raspberry pi running the OS that we will be using. I will make myself avialable as often as possible to help wit testing and troubleshooting the physical hardware. Please contact me with any question as there may be details that I have left out that could be useful. thank you in advance for your help.
