USB for Remote Desktop - repost

Essentially, this tool will be used to flash phones over the internet. I require this ASAP. Server App: When the client plugs their USB into their computer it should appear as if they plugged it into our server. I will need an executable file in which my client will run in order to grant me access to their drivers (USB). When i connect to the client, their devices plugged into their computer should appear as if they were physically plugged into my computer. From my server app i should be able to double click one of the clients and connect to them. List should appear with first connection listed first. I have a software in which runs on my computer only, however it requires the USB device to be plugged directly into the computer. By this software i should be able to do my job remotely. (teamviewer does not work because i would have to install my software in the clients computer in order to flash the phone, ofcourse this will not work) Client App: The client should be able to download the connection file. The app will require an access code (From MYSQL), once the code is valid the client should show up on the list in the server app. After i complete my job, i should be able to destroy the session / access number so they can not use the software any longer (unless they have another access code / PIN number) MYSQL will be hosted by my server, i will create the script that will create the access codes myself, with the information about the phone myself. Example of the software: [login to view URL] Ofcourse i would need mine custom and easy for my not technical customers. Server app: Look at image attached Client app: Look at image attached
