SysTick with custom HID problem

Hello

I have a problem with a SysTick working together with a custom HID (STM32_USB-FS-Device_Lib_V4.0.0).

I am running at 72 Mhz, and if I don't init the USB my SysTick irq is firing every ms as I expect. However, if the usb is initialised, the SysTick firing rate drop by about a factor 8-9.

I'm pretty sure this is a trivial mistake, but I can't seem to find it.

Thanks

Michael
