Hello,
This is more a USB question then zd1211, but I hope
somebody can explain:

If you look at zd_usb_enable_int() in zd_usb.c,
the USB transfer_buffer is currently kmalloced; Any
idea what is the advantage of using a DMA buffer
instead?  

And BTW, there is a comment there saying:
/* TODO: make it a DMA buffer */


Regards,
Xu
