USB voltage is only about 5V anyway and the maximum length for a cable is worked out for it’s maximum efficiency.

So effectively you are doubling the length of the cable therefore dropping the voltage to below what is required to run the equipment.

This is because the longer the cable the more resistance over distance and is worked out using the Ohms Law formula which is volts/current/distance

You want something like this

USB signals do have problems travelling over large distances due to loss in signal.

get a good quality USB extension and try that, failing that, use a powered USB 2 hub

You cannot connect a USB 2.0 device to a USB 2.0 port with a USB 1.1 extension. While the port and device can negotiate, the extension cable is not smart enough to negotiate since it’s just wires. The port and device negotiate USB 2.0, which the cable cannot support.

This exact same problems occurs with gigabit Ethernet over wiring intended for fast Ethernet and with SATA 3.0Gb/s over wiring intended for SATA 1.5Gb/s. The devices negotiate the highest speed they both support and if the wires connecting them don’t support it — boom!

Get a USB 2.0 extension cord and all will be well.

Based on the information you provided, if the extension is damaged, poor quality or too long, you wireless device is probably not getting enough voltage.
