How to Install Qualcomm HS-USB Modem 90A8 Driver

1. Check your device and system. Open Device Manager, locate the modem or unidentified USB device, and check its hardware IDs under Properties > Details. Confirm your Windows version and system architecture before choosing a package.
2. Select a compatible download. When choosing a Qualcomm HS-USB Modem 90A8 driver download for Windows, verify that the package lists your hardware and operating system. For Windows 10/11 searches, note that Windows 11 is not listed among this device’s supported systems; do not assume compatibility.
3. Download and extract the files. Use a trusted manufacturer or device-support source. If a free download is offered, check the package details and digital signature where available, and avoid installers that bundle unrelated software.
4. Install the driver. Run the supplied setup program, if included. Otherwise, right-click the device in Device Manager, select Update driver or the equivalent option, and browse to the extracted driver folder.
5. Reconnect and verify. Restart Windows if prompted, reconnect the device, and confirm that Device Manager no longer shows a driver warning. A working mobile broadband connection may also require compatible connection software and an active service plan.

Keep the driver updated when a compatible release addresses a problem you are experiencing. The latest version is only useful if it supports your exact hardware and Windows edition; review compatibility notes before an update, and retain the previous working package in case you need to roll back.
