STM32F 407 &&& 2 USB MASS STORAGE DEVICE

[jack1985q1]

Good evening guys, I have an educational project for the USB protocol on the stm23f407 discovery board I made the project on two sensors and each sensor is written to a flash drive on a separate usb_otg_host port because the stm32f407 discovery board contains 2 usb_otg_host The problem that is happening to me is that when I write on each flash, it is fine and working, but when I put the 2 flash together or in the first order, then the second, the processor hangs and stops responding Can you help, thanks a lot

> processor hangs and stops responding

Debug as usually. Find out what does "processor hangs" mean - e.g. a HardFault? - and then proceed as with your own code, when it "hangs".
