The device specification says its a HID class device.
It's working in Windows.
But the descriptor structure in linux has 0xFF for DeviceClass,
DeviceSubClass & DeviceProtocol ( Vendor specific ? ).
That's why i started writing a seperate driver.
I am supposed to use set_report for sending data
Are you sure it's an HID class device? Most of these devices are Storage
