USB extension cable compatible with USB 2.0 and 1.1 that feeds back the signal on those occasions when it is necessary, either because the peripheral requires a good signal for its correct operation, or because the maximum distance allowed by USB is exceeded.
In addition to a simple cable, it has the electronics necessary to perform this function.
It must be taken into account that each extender consumes 0.14A from the computer's USB port, with which the amperages of each of the extenders used must be added, plus the consumption of the USB peripheral itself (the theoretical limit of a USB port is 0.5A).
