MSP430F5528: MSP430F5528 - USB issue

Part Number: MSP430F5528

Dear Sirs,

Let me introduce myself. I'm Samuel Ignacio Ramirez Gutierrez, Engineering manager of Identix RFiD Inc.

We have a couple of products based on the MCU MSP430F5528IRGCR. Some days ago, we received the feedback of a customer explaining that the PCs (running Windows 7) loss the communication with our device. Our device is connected to the PC via USB port, after the issue, they can't open the port on a logically way. The only way to solve it is to disable and enable the device at the PC.

We want to know if you received any related issues regarding this behavior.

Thanks in advance for your support.

Best Regards,


Samuel Ignacio Ramirez Gutierrez

    Hello Samram,

    Typically when we see driver issues, its on the Windows side fo thinks, especially with Windows 10 as they changed how typical driver downloads work. Typically, a different USB port or re-downloading TI USB Drivers will solve most of these issues. I haven't heard of the exact situation you are describing with Windows 7 though.

    Without additional information on how you use the USB and exactly what kind of error you are seeing, its hard to say what the error could be. If you can reproduce it in your lab with a debugger attached to the device, it may give some more information on the matter.
