Maybe we can work > together to produce something that fits both our needs? Ofcourse, I'd love to help you out! My goal is to implement a SD-Bus on which the SD/SDIO drivers can attach to. My knowledge of FreeBSD Kernel is poor and at the moment I'm walking through driver sources of usb, trying to understand the (New-)Bus architecture (hope it's the right place?!). So if you still want to work with me ;-) , I could implement the bus interface on which your MMC/SD stack can attach to. Regards, Sashi
