ESP32-S3 USB host - USB 3.0 flash memory stick

Postby Jorgen » Sun Jun 16, 2024 12:33 pm

I am running the ESP32-S3 USB host MSC example in framework 5.2.1. It works well for USB 2.0 flash memory sticks. In the documentation is stated that it supports full speed and high speed. USB 3.0 flash memory sticks are super speed.

Are there any plans to support USB 3.0 flash memory sticks also?

Regards,
Jorgen

Those sticks should simply revert to full speed if you connect them to an ESP32S3, so they'll work transparently at the max speed the ESP32S3 supports.

Thank you for the reply.

I have tried connecting my USB 3.0 flash stick, but it was not recognized. I use the ESP32-S3 framework 5.2.1 example USB/host/msc.

Problem solved. I tried another USB 3.0 64GB flash memory stick. It was accepted by the software.

Looking closer, it is formatted as FAT32 (surprising). EXFAT is not enabled in the software example.
