Any idea? Any suggestion?

For the first part, you do not need to use "ChipGenius", the only thing you need is the VendorId and ProductId of your device then look for the chip used by your device using an online web site that gather this kind of information such as http://flashboot.ru/iflash/ To get vendor id and product id just use lsusb. Example: Bus 004 Device 012: ID 1f75:0917 Innostor Technology Corporation In this example, vid == 1f75 and pid == 0917.

About the tool needed to reprogram the chip, I am now investigating to get one working using wine, usb support is still experimental but some work was done: http://wiki.winehq.org/USB
