Erm im sorry I wasn't very imformative. thanks for not shouting on me.

I use the USB fifo that is built in the DK.

normally when I enter my DK's USB to the correct USB hub. the windriver/driver I made using windriver design recognizes my device well.

even when I put an empty VHDL design it regonizes the DK USB as 8 bit fifo and allows me to read/write to it.

but sometimes when I add vhdl code windriver/mydriver fails to recognize the device at all. I have no clue what code changes cause the problem and it drives me mad.
