Symptoms
Cannot share content using original CISCO USB-C cable? Prod.#: CAB-USBC-AC-9M=
Diagnosis
the 9m cable has a specific direction. Pls. check the plugs of the cable: one end says PC; the other end says CODEC
Unfortunately nothing else warns the user of this!
Solution
maybe you just need to change the direction of the cable.
Check as well if your Laptop supports Alt DP Mode
