MCF5329 with USB low-speed

Hello!

I'm trying to implement an USB-stack of my own. The (nearly) the complete handling seems to work on full-speed, but if i switch to low-speed (through d-minus pullup instead of d-plus pullup through external max3353e), nothing is working (no packets are send properly). is there a register in the mcf5329 to tell the internal transceiver that it should run on low-speed mode now? Somehow i don't see that kind of configuration.

 

Thanks in advance!!
