It may be an issue with the USB port you are using. Since the cable can be used for powering the Ledger it's obvious that the cable is functional.
The USB port has no problem whatsoever, I have checked everything works on the PC, Yes it can only charge but cannot be connected to the PC with the built-in cable except for other cables that work properly.I don't know where the problem lies, now it's normal with another data cable, trying to upgrade the firmwae to the latest version works fine and smoothly.
Now not so worried.
