Usb generic driver

Hi! I would like to connect generic usb device to rasp. Known vid & pid, 1 device / 1 config / 1 interface only, 1 bulk in + 1 bulk out endpoint (and control ep ofc). Will be happy to send and receive fixed size packets on those endpoints. What is the preferred way to do so? Thank you in any advance.

Re: GPIO pin reading

Hi! I am new to raspberry, and would ask some gpio reading related question. I downloaded bcm235-arm-peripherals.pdf doc from net, and not found any mention about gpio pin direction register in chapter 6.

Re: What should I do with my Pi?

Ppl is it possible to use rasp as a mass storage device? There is a micro-b connector on rp b+, is that a fully functional client usb connector, or is that a power-purpose connector only? Thx

Re: New to Raspbian and Linux? Start here...

Is there gcc toolchain (with Rasp own sdks) built into Raspbian? "cc" does nothing :( I prefer compile & link applications for Rasp _on_ Rasp instead of a dedicated linux. It will be eXtreme handy.

I could use Raspberry as this hardware is (fast cpu, 64mb+ ddr memory, gpios / interrupt source lines, sd card, ethernet). However i need this _without_ OS for better performance. I need just a C compiler and C stac...
