Details

An iPad Pro that charges fine but won't show up on a Mac, or shows up and never charges, can share a single cause in the USB IC. The 343S00105 is a 36-pin USB charging IC listed for the iPad Pro 10.5 (2017) and the first iPad Pro 12.9 (2015).

The listing names the A1701 and A1709 for the 10.5, and the A1584 and A1652 for the 12.9. It doesn't give a board position.

Problems linked to this chip

Abnormal connection to a computer.
No charging from a working charger.
Charging that cuts in and out.
Slow charging on the original adapter.

Getting at the board

Rule out the cable, the charger and the charge port first. iPad Pro screens are laminated and fragile, so use gentle heat and plenty of picks to lift them. Disconnect the battery before you touch the logic board.

Find the chip with the board view, shield nearby parts and lift it with hot air. Fit the new one on fresh flux, then test charging and a computer connection before closing the iPad.
