Re: [usb] USB Amateur desperately looking for help

[bhpchan@engmail.uwaterloo.ca]

how hard is it to get the chip, ram, rom, connectors on a board?

If that's too difficult I'm planning on getting one of those pre-made USB 
enabled boards such as the devasys.com I2CIO boards.  I'll make my 
own IO board with the ADCs and use the I2CIO board for my USB 
applications.  What do you think?

Also, do I need to write my own device drivers if I use these USB 
enabled boards?

Thanks

Bobby
