Hi, guys! I need help with following. My midi keyboard M-Audio CTRL49 fell off the table while the cable was connected. The connector broke several smd-components on the board (marked D2 and R26). I think but not sure that D2 is some kind of diode array (in package like SOT-363 or similar) which protects the USB. A resistor R26 between 1-3 USB legs might be used to set data transfer rate. How to find out what components should be on the board?
upd: sorry for google translate

 

How to find out what components should be on the board?

Obtain the schematic and parts list for the machine.

 

Of course, but I don't have part list or something like schematic... Any suggestions?
