So we are in the sensor repair business as well as being in new technology sales, service, training and installation.

On the sensor repair side we run into a pretty common issue…

We get sensors in for our repair service and have to call the doctor and tell them there is nothing wrong with the sensor. We are often met with pure confusion at this point. Of course we offer advice and any help to get there problems at their office solved and we charge nothing for sensors unless we complete a repair.

A likely failure point for most computer systems are USB ports, consider a Powered USB HUB

Assumptions:

Usage: 8 plug/unplug cycles per day

Environment: High-use (e.g., office, lab, dental)

Time period: 6 years

Estimated Wear from Plug/Unplug Cycles:

8 cycles/day × 365 days/year × 6 years = 17,520 cycles

Most consumer-grade USB ports (Type-A) are rated for 1,500 to 5,000 cycles according to USB.org and manufacturer specs. So:

Low-end spec (1,500 cycles): Exceeded in 6 months

Mid-range spec (3,000–5,000 cycles): Exceeded within 1–2 years

High-end spec (10,000 cycles): Exceeded in 3–4 years

Failure Rate Estimate (6 Years, High Use):

Port Build Quality Expected Failure Rate by Year 6

Low-end consumer USB port 60%–90% failure likelihood

Average consumer USB port 40%–70% failure likelihood

Reinforced or premium port 10%–30% failure likelihood

Additional Failure Risks in High Use:

Motherboard trace damage due to constant strain

Broken/bent contacts

Loosening or wiggling ports from torque stress

Occasional shorts from debris or poorly made cables

Summary:

In consumer-grade desktops with daily USB usage like this, at least 1–2 ports are likely to fail within 3–4 years, and by 6 years, most will show wear or unreliability unless reinforced hubs or port extenders are used.
