If a USB device does not work on the HP Spectre x360 14, try the other port, a different cable and another computer. The Spectre has USB-C Thunderbolt ports and a USB-A port, and a device that needs more power than a port provides may disconnect. Open Device Manager for a warning on a Universal Serial Bus controller, and look at Settings, Bluetooth and devices, USB for messages. Disable USB selective suspend in the power plan if devices drop out after idle. Update the chipset and USB drivers through HP Support Assistant.

Exact questions
Common questions
How many ports does the Spectre have?+
It has two USB-C Thunderbolt ports and a USB-A port on current models; check your configuration.
Can I charge and use a display at once?+
Yes, with a dock or one port for each.
Why does my drive keep disconnecting?+
Power saving or a weak cable. Try a powered hub.
Is the Thunderbolt port also USB?+
Yes, a Thunderbolt 4 port is also a USB-C port.
Why does my USB drive not appear in File Explorer?+
The drive may need a driver, have no drive letter or need formatting. Check Disk Management in Windows.
Can I charge my phone from the Spectre's USB-C port?+
Yes, but the laptop may limit the power; use a charger if you need speed.
Why does a USB device work in USB-A but not USB-C?+
The USB-C port may need an adapter or may carry only some signals. Use the right adapter.
How do I check USB devices in Windows?+
Open Device Manager and expand Universal Serial Bus controllers.
Does the Spectre have USB 4?+
Thunderbolt 4 ports also work as USB 4; check your model's specifications.
Can I use a USB hub on the Spectre?+
Yes, a quality hub works. A powered hub is best for drives.
Why does my keyboard dongle not work in the USB-C port?+
It needs an adapter or the USB-A port. Use the right connector.
How do I safely remove a USB drive?+
Eject it from the taskbar or File Explorer before unplugging.
Why does my phone not charge from the Spectre's USB-A port when the laptop is off?+
Many laptops cut power to USB ports when off. Use a charger, or enable charging while off in the BIOS if it is offered.
Can a USB-C hub make the Spectre run hot?+
A hub that carries video, data and power adds heat. Use a quality hub and give the Spectre airflow.
What is the difference between a Thunderbolt port and a plain USB-C port?+
A Thunderbolt port is a USB-C connector that also carries very fast data, video and charging, and it supports docks and external displays. A plain USB-C port may carry only data and power, so check the symbol beside the port.
Why does my external SSD run slowly on the Spectre?+
It may be on a slower port or cable, or the drive may be throttling when hot. Use a Thunderbolt or USB 3.2 port and a cable rated for the drive's speed.
How do I fix a USB device that Windows says it does not recognize?+
Unplug it, restart the Spectre, try another port and cable, and update the chipset and USB drivers. A device that fails on every computer is faulty.
Can I use the Spectre's USB-A port for a mouse dongle?+
Yes. If the dongle conflicts with Bluetooth, move it to a port on the other side of the laptop.
Should I eject drives before unplugging them?+
Yes, use Safely Remove Hardware or eject in File Explorer so Windows finishes writing before you pull the cable.
