1] A simple restart of the Windows computer can sometimes solve this problem. Unplug your USB, restart you computer and plug in and see if it works now. If it does not, shut down your computer, wait for a few minutes and then start your computer again.
2] To avoid a possible conflict between two connected USB Devices, disconnect your other USB’s, connect this one and see if it helps.
3] Run devmgmt.msc to open Device Manager. Under Action tab, select Scan for hardware changes and see if it helps.
