# How to fix USB not recognized for HP printer?

If your HP printer USB isn't call **1-844-957-6312** connecting to your computer, this guide will walk you through step-by-step fixes for the “USB not recognized” error, from simple cable swaps to driver reinstallations and deeper USB controller resets. Follow these instructions to identify whether the problem is the cable, the computer, or the printer itself.

### What “USB not recognized” means

When a computer displays “USB device not recognized” for an HP printer, it means the operating system can’t properly identify or communicate with the device. That could be due to a physical connection problem (bad cable or port), driver or firmware issues, USB controller corruption on your PC, or an internal hardware fault in the printer.

### Quick checks — do these first

Before diving into software changes, start with basic hardware checks that solve most cases:

* Try a different USB port on the computer. Front and back ports can behave differently.
* Use a different USB cable (make sure it’s a data cable, not charge-only).
* Connect directly to the PC — avoid USB hubs or docking stations.
* Power cycle both devices: turn both off, wait 30–60 seconds, power the printer on, then the computer.
* Try the printer on another computer to isolate whether the issue is the PC or the printer.

### Inspect the printer and cable

Physical damage and dirty connectors are common culprits:

* Look for bent or broken pins in the printer’s USB port.
* Ensure the USB cable end is clean and intact; dirt or oxidation can interrupt data lines.
* If the printer has multiple USB ports (rare), try a different one.
* Use the original power adapter and avoid underpowered surge strips or adapters.

### Reinstall or update drivers and HP software

Driver corruption or version mismatch often causes recognition errors.

* On Windows: open **Settings → Apps** or **Control Panel → Programs and Features** and uninstall HP printer software and drivers. Then restart the computer.
* On macOS: remove the printer from **System Settings → Printers & Scanners** and delete any HP utility apps.
* Download the latest full-driver package for your exact HP model from HP’s official support website. Install the driver following HP’s instructions, connecting the USB cable only when prompted during setup.

### Reset USB controllers (Windows)

If the USB stack in Windows is confused, resetting controllers can help:

1. Open **Device Manager** → expand **Universal Serial Bus controllers**.
2. Right-click each USB Root Hub and Host Controller → select **Uninstall device**. (Don’t uninstall keyboard/mouse controllers you need to operate.)
3. Restart the PC; Windows will automatically reinstall USB controllers.
This often resolves driver-level conflicts and refreshes USB hardware enumeration.

### Check Device Manager and USB logs

Device Manager provides clues:

* Look for unknown devices or entries with a yellow exclamation mark.
* Right-click the problematic device and choose **Properties** → **Events** to see error messages.
* In some cases, uninstalling the ghost device and performing a rescan resolves recognition issues.

### Power management and conflicts

Windows can disable USB devices to save power:

* In Device Manager, for each USB Root Hub: **Properties → Power Management** → uncheck **Allow the computer to turn off this device to save power**.
* Temporarily disable third-party antivirus or firewall software during driver installation (re-enable afterward), in case they block USB driver installation.

### Firmware and HP support tools

Firmware bugs can affect USB functionality:

* Check HP’s support page for firmware updates for your printer model. Follow the update instructions carefully — some firmware updates require a stable USB or network connection.
* Use HP Print and Scan Doctor (Windows) to diagnose common issues — it can often detect driver problems and suggest fixes.

### Test on another computer

Testing the printer on a different PC is a key diagnostic step:

* If the printer is recognized on another computer, the fault lies with the original PC (OS, drivers, or USB hardware).
* If it fails on multiple computers, the printer’s USB interface or internal hardware may be damaged.

### When hardware repair is needed

If all software troubleshooting fails, the printer may need service:

* Faulty USB ports or damaged internal boards require professional repair or replacement.
* If the printer is under warranty, contact HP support for authorized service. A certified technician can test internal connections and replace defective components.

### Preventive tips

* Use good-quality, shielded USB cables and avoid repeatedly bending connectors.
* Connect the printer directly to the computer rather than through a hub.
* Keep drivers and firmware updated periodically.
* Avoid unplugging the printer mid-transfer; safely cancel jobs before disconnecting.
* Store cables away from heat and moisture to prevent degradation.

### Summary

A “USB not recognized” error with an HP printer is almost always solvable with a sequence of logical checks: try another cable/port, test on a second computer, reinstall drivers, reset USB controllers, and update firmware. These steps pinpoint whether the issue is the cable, the computer, or the printer hardware. When in doubt, professional support can diagnose and repair internal faults to restore reliable printing.
