Up to what length do USB cables function?
The maximum possible length of USB cables varies considerably and is defined in the bus specification for USB. The maximum lengths are different and depend on whether USB 2.0 or USB 3.0 is concerned. For USB 2.0, the maximum cable length is approximately 5m, for USB3.0 approximately 3m. But the cable length can vary from these values slightly, depending on the cable used.
