stm32f407 Usb host Hub problem
I use stm32f4discovery in FS_HOST mode of HAL library V1.4.3 11-12-2015
Through FS hub is connected to the host LS mouse.
The problem arises when reading descriptor mouse, when they begin to be used PREamble packages. Sometimes after USB_OTG_HC_StartXfer procedure query to mouse usb port there is a disable. Attempting to sent immediately after the SOF was unsuccessful.
To continue the work required to re-initialize USB core.This is not always, but often enough.
I found a similar problem on the Internet. This is not always, but often enough. I found a similar problem
Can someone use a hub for ls device?
