**Unable to launch a new system**

**New LimeSDR USB Type A**.

December 07, 2025

Hello

Just received a new LimeSDR-A card

Purchased through Crown Supply and received two days later through MOUSER USA TEXAS

To date, it is impossible for me to see the correct driver “Myriad-RF LimeSDR-USB”

But appears: “Cypress FX3 USB BootLoader Device”

If I want the Driver to be replaced by “Myriad-RF LimeSDR-USB”, it appears but does not want to be recognized

On my previous LimeSDR card, the driver is well recognized: “Myriad-RF LimeSDR-USB”

Very annoyed because currently can’t continue to LimeSuite and the rest

I’m on Windows 11 64-bit Version: 25H2 Build: 26200.7309

What can be done to solve this unfortunate problem

Thank you in advance for your help

Check if your board has a jumper on the FX3 BOOT pins

Then the firmware migth be missing, you can try to update the firmware using Cypress FX3 tools [LimeSDR-USB User Guide - Myriad-RF Wiki](https://wiki.myriadrf.org/LimeSDR-USB_User_Guide#Uploading_firmware_to_the_FX3_RAM)

Or check if the FX3 Boot jumper actually has metal in it to make contact,

It’s impossible to install the 8-year-old driver (2017) under Windows 10 when we’re currently in the final stages of Windows 11.
