I am using a Gear Head USB card reader on Ubuntu 11.1 and it works great. The model number of the device is CR3000MSD. I am looking for some working source code in any language really that will allow me to access the device at the hardware level. In other words C++ library, open source driver etc? I know there must be source code since the device is working perfectly on Ubuntu 11.1. The reason I started using Ubuntu is so I can pick a part code for these types of devices. Does anyone know where I can find some working code for this device?
