If you use a USB/serial converter, the device will appear to the host as a COM port, not a HID.

If you want a HID, you need a USB controller programmed with HID firmware.

Dear Jan Axelson,
 
 Thank you for your answer , but i just want to actually convert the I/O of USB HID device into serial . But the problem is I have to read it in the micro-controller not PC. Now all the convertor (USB to serial) are actually slave usb , which act as the virtual comport when connected with the PC which acts as USB HOST.  If you can kindly guide that such facility is achievable at the embedded system level or some COTS components available for this.

regards.

If you want to create a HID/serial converter, write device firmware that sends all data received on the device's serial port to the host as a HID report and writes all data received in HID reports to the serial port.
