[NOT Solved] F407 and SanDisk Cruzer Blade 16GB don't work (32GB work)

[#1]

I tested 3 pendrives, 4GB (Samsung?), 16GB and 32GB (SanDisk Cruzer Blade).

Two worked on the STM32F407VG.

SD card adapter also doesn't work, 8GB (Kingston), 2GB (Generic), 16GB (Sandisk Ultra).

SanDisk Cruzer Blade 16GB don't work.

Using USB host with STM32CubeIDE 1.3 (Version 1.4 does not work with ST-Link V2 :expressionless_face:)

​In case anyone has problems with this, I leave it registered that it can be common.

All devices run on Windows 10 x64 and Android 10 (Smartphone).

don't work means

showing wrong storage capacity or simply display that not recongnised ?

[#3]

The term Does not work means that the automated program for writing to the USB stick has failed to perform the task.

Thanks, yes I configured Vbus, this code is an example, and the IDE already suggests that this configuration be done.
