USB Spec

[theubu]

Anyone here have a good USB 2 /> spec laying around? I'm looking to quickly whip up a driver.


Thanks

get the official spec: its free and guarenteed to be complete and acurate though the official USB site was confusing last time I checked (though that was before the USB2 spec was finalized so its prob better now) also it (was) availible from both MS and Intel websites

Official USB website:http://www.usb.org/developers/docs/

make sure you also look at the *HCI specs as that is your first driver layer

USB is very hard to implement (relative to the simpler devices) and iirc requires several multi-level drivers (drivers within drivers) but if you have a good driver system and full filesystem drivers it should be easy enough to implement a flash-drive driver since they all use a standard universal system thats why winXP never needs drivers for any of them (many mp3 players now also show up using the same standard)[/url]
