What ive discovered so far:
The usb functions are handled by a MSIC by Silicon Labratories, its called USBXpress model CP210x
Mixed-Signal ICs - USB to UART Bridge
You can download the api for the chip, but be warned that the greddy software won't work if you install the usbxpress drivers..
so far, i can connect to the device and open a serial connection, but im just trying to find the speed stuff... ill look into the blue serial protocol a little more, hopefully the ultimate will also be the same...
Ill mess around more with it tomorrow
