That "USB device not recognized" pop-up is one of the most annoying Windows errors because it tells you nothing about the actual cause. Before you assume your drive is dead, work through these fixes — in my experience, fix #3 alone solves it for most people.
1. Try a different port (and skip the hub)
Front-panel ports and cheap USB hubs cause half of these errors. Plug the device directly into a rear motherboard port.
2. Restart with the device plugged in
Unplug it, shut down fully (not sleep), plug it back in, then boot. This forces Windows to re-enumerate the device.
3. Reinstall the USB controllers
Open Device Manager, expand "Universal Serial Bus controllers", right-click each "USB Root Hub" and "Generic USB Hub", choose Uninstall device, then restart. Windows reinstalls them automatically. This is the fix that works most often.
4. Disable USB selective suspend
Control Panel > Power Options > Change plan settings > Change advanced power settings > USB settings > USB selective suspend > set to Disabled. This stops Windows from cutting power to "idle" ports.
5. Update the chipset drivers
Generic Windows drivers misidentify controllers. Grab the chipset driver from your motherboard or laptop maker's site (Intel, AMD, or the OEM).
6. Check for the yellow warning in Device Manager
If the device shows as "Unknown USB Device" with a yellow triangle, right-click it > Update driver > Search automatically. If that fails, note the error code — code 43 often means a hardware handshake failure, not a dead device.
7. Test on another computer
If it fails on two machines with different cables, the device itself is likely the problem — not Windows.
8. Run the hardware troubleshooter
Settings > System > Troubleshoot > Other troubleshooters, or press Win+R and run: msdt.exe -id DeviceDiagnostic
9. Check USB settings in BIOS
On some desktops, USB legacy support or xHCI handoff settings cause detection flakiness. If you recently changed BIOS settings, reset to defaults.

What fixed it for you? The controller reinstall (fix #3) is my usual winner.
