Connected USB device not detected

I have implemented the USB MSC Host application on a STM32F4, but it never detects the connected USB stick in the USBH_core state machine. I also know that the OTG_FS_IRQHandler() never gets executed the whole time. I guess there is something wrong in the usb_bsp.c file, but I used the one for STM32F4 from the project "Audio_playback_and_record". Unfortunately this is  a library for USB device, not host. Do I have to apply any changes to this file to make it work for hosts or is it the same for hosts and devices?

Link to my usb_bsp.c:

Or are there any system clock values I have to set?
