Problem in “USB device not recognized”.
When inserting a USB flash drive on the computer, you normally see the message “USB device not recognized” on corrupted devices. But this is not always the case. Sometimes the problem is not with the USB flash drive but with the USB port. Since a normal CPU has several USB ports, try connecting your USB flash drive to other USB ports then see what happens.
If only one port reports that message and the rest are working then that port must be damaged. Don’t use that port again to avoid data loss. But if all USB ports report the same error message then it is possible that your USB flash drive is corrupted. You can fix this issue by formatting your USB flash drive and it should be back to normal.
The file or program “svchost.exe” generally means Service Host. It is a process on the computer that controls or hosts other separate services that Windows or the operating system uses to do different functions. If you will open the Task Manager, you might notice several instances of svchost.exe running on the computer. See image.
Each instance has different services. Once instance might contain one service for a program and another instance might contain several services associated to Windows.
