- GigachadThe thing that has been bothering me for a while is that the USB spec allows for software detection of capabilities. You can read the emarker data and see the supported protocols, speeds, voltages, etc.But there is not standard for usb controllers to present this data to the OS. So it’s stuck in the low level firmware and never passed up. In theory we could have a popup box that tells you that both your computer and other device support higher speeds/more power, but your cable is limiting it.Apple seems best able to do this since they control the hardware and OS, yet they aren’t doing it either. Users are just left to be confused about why things are slow.
- seanalltogetherI wasn't surprised to learn that when Linus Tech Tips released those new usb-c cables, that they all sold out almost instantly. They put their entire reputation on the line to claim (and label) the exact capabilities of their usb cables. Isn't that all we really want?
- ChrisMarshallNYThis isn't a Beagle. When I first read the headline, I was hoping that it would be more than a smart continuity tester.It seems to be a more comprehensive "Make sure the lines go where they are supposed to" tester. Looks pretty good.But the devices that test things like transmission speed, are a lot more expensive.I think that many of the issues that this device tests, can be mitigated by simply buying cables from reputable sources.
- ameliusI want one that sends a pseudorandom data stream and tells me the bit error rate.
- atoavOne thing to realize is that especially for high resolution video cables these cheap testers can't really deliver. The way to test them is a eye diagram (see: https://incompliancemag.com/eye-diagram-part2/ ) and testers with that capsbility cost upwards of 10.000 Eurodollars.
- OnavoI just want one that tells me the maximum voltage and current supported by a USB C cable.
- EisensteinHopefully they used connectors with a high mating cycle rating.
- Modified3019I’ve had one for a while as well. I don’t use it often, but frankly I couldn’t sort my cables without it.
