Encoding of 64-bit double

This appears to be a fixed-point (rather than a floating-point) format. If you treat the 64-bit values as signed integers and divide by 4398046511104.0, you will get the decimal values you show. e.g. ...

The Nokia CA-50 cable has a longer USB port. Does it hide any kind of chip?

Older Nokia phones use a serial (db-9) cable so if this cable supports flashing it likely includes a usb to serial converter (eg ftdi chip)

The Nokia CA-50 cable has a longer USB port. Does it hide any kind of chip?

If there is any chip inside the cable, it will use the 5v line as power supply. So, you have to measure resistance from gnd to 5v and compare it with another cable. Usually, the resistance is so high ...
