① Starting Point: How the Customer’s Voice Emerged
Chiza is a multi-device power user who is extremely sensitive to new technologies. After purchasing the latest Mac Mini M4, he paired it with his Windows mini PC and selected our HKS0402A1U-USBK KVM to build a seamless dual‑system workstation.
But soon, he reported in a support ticket:
When switching to the Mac Mini M4—
• Keyboard and mouse were not recognized
• Only one display turned on
He found on an Apple forum that this might be a known compatibility issue, so he contacted us with an initial diagnosis already in mind.
② Real Confusion: This Was Not a “Small Glitch” for the Customer
For Chiza, this was not an occasional bug but a critical issue that directly impacted productivity:
• His goal was to build an efficient dual‑device workstation
• macOS input failure + one display not lighting up completely broke his workflow
• He was unsure whether the issue came from the KVM, macOS, or his hardware setup
This “uncertainty” is often the most painful part for users.
③ Our Evaluation Process: From “Doing as Expected” to “Rethinking the Approach.”
When the ticket arrived, Kelly’s first reaction was to confirm the technical point: this was a known compatibility issue between certain older KVM controller chips and the new macOS Sequoia.
Originally, she could have followed the customer’s expectation—
Provide a firmware upgrade package and let him update it himself.
But the firmware upgrade was extremely complicated:
• It must be performed on Windows
• The KVM casing has to be opened
• The operation carries high risk
While reviewing Chiza’s device list, one detail made Kelly pause:
His two systems used Thunderbolt 4, HDMI, and DP—
And the older KVM he owned was not the most suitable match for this setup.
In other words:
Even if the upgrade succeeded, the overall experience might still be suboptimal.
This directly changed our initial judgment.
④ Action and Change: From “Fixing the Issue” to “Ensuring the Best Customer Experience.”
Kelly still provided the firmware upgrade option in her email, but she also introduced another suggestion:
“Instead of taking the risk of upgrading the old unit, it may be better to switch to the newest HDK202‑P23.”
She explained the reasons very clearly:
• Better input compatibility: HDMI + DP perfectly match the two systems
• Firmware updates no longer require disassembly
• USB 3.0 ensures smoother peripheral performance
Behind this recommendation was a shift from “patching a problem” to “designing the best path for the customer proactively.”
⑤ Customer Feedback
A few days later, Chiza purchased the new model and wrote back to us proactively:
“Based on your suggestion, I upgraded to the HDMI+DP model. It works much better now… Thank you for the help.”
In the satisfaction survey, he gave the evaluation: “Very good, I am very satisfied.”
This feedback validated our decision.
⑥ How This Experience Changed Us
Chiza’s case reshaped how we approach both pre‑sales recommendations and after‑sales troubleshooting:
• We now proactively evaluate the customer’s device structure in similar tickets instead of only fixing the immediate error
• We added a guideline to our internal knowledge base: “When firmware upgrade cost is high, suggest a more compatible product.”
• We realized that customers’ real usage scenarios should directly influence the solutions we provide—not mechanical troubleshooting steps
This was a typical case of co‑creation:
Not because the problem was huge, but because the customer’s feedback taught us to “offer what fits best, not just what barely works.”
