Hi, i need your help, guys!
Here is the thing: I get light in the mouse (both port). However, the USB port doesn't work.
Do you guys have any advice/hint ?

Any history liquid etc? Very common for both L4600 and L4610 to fail, so I'd say replace both of those and go from there.

None of USB ports works?
Then could be PCH issue.
Check resistance to ground and compare values on data lines.

Apart of L4600/10 there is U4650 (one port only), which can be removed; need to mount R4651/52 then.
