USB device not recognized error is coming
This problem could arise from two possible sources. One is due to a malfunction in the USB hardware whether it is a flash drive or a peripheral like keyboard and mouse. In this case the best solution would be to check if the driver needs an update or if the cable has any discontinuity at any point. If that is not the case, the device may have a serious circuitry issues in which case a simple troubleshoot might not be the solution. But many of these cases are due to a problem associated with your host. Low speed port which could easily be solved with an alternate high speed port, failure to wait until the operating system initializes that can be avoided by unplugging your USB device and plugging it again or restarting your system and there is the obvious case of malware problems which could affect your hardware in which case an antivirus should always be installed and updated on your computer for a regularly scheduled scanning.
