you can see there is no mention of 4770 in the coding....if you manually add 4770 lines, it still doesn't work..........moreover, in details of device in device manager, it shows the hardware id of this device as "USB\VID_A108&PID_4770" while in the file it says like "VID_601a&PID_4760"..........

so whats going on here?? why there is a10 in ingenic device??? when i added this hardware id in inf file and then tried to install driver, it detected the driver but said it is not signed, i installed it anyway but the process still doesn't work........when i start usb tool to flash firmware and follow steps, nothing happens...........we really need some expert help here.........
