~” See the VDIP1 command list for the full file operations. The Arduino USB Host Shield is based on the MAX3421E (datasheet), which is an USB peripheral/host controller contains the digital logic and analogue circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant to USB specification rev 2.0.
Some common commands would be “~DIR~ ~CD DIRNAME~ ~CD.

The sketch allows sending of any command via the Serial monitor for doing testing. Update: I changed the sketch and schematic / pic to include the RTS / CTS flow control. Overall Im pleased to have this working but it is frustrating that the shield does not come with any documentation or datasheet I had to piece together this. Keep reading for the schema, pic and sketch. I am posting an early version of the sketch just so i can get a good example and a picture / schematic out so expect updates later. After switching to the NewSoftSerial library everything started working and I had no trouble doing a DIR and creating a new file on the flash drive. The first attempt was to use the AFSoftLibrary and it just did not work properly causing some strange looping of the Setup() method.
I chose the NewSoftSerial library to give access to the VDIP1. To get around this limitation there are a number of libraries that allow serial communication over non-serial pins. Because the Arduino only has one TX / RX serial pin if you connect it using them you cannot communicate with the computer over the built in USB UART on the Arduino.

C Software support for new devices is constantly added at the moment, code for USB keyboard and PS3 controller are ready. SainSmart Uno 328SainSmart Diecimila/Duemilanove 328.
All SPI signals are sent through a hex converter to step them down to 3.3V. Power from that pin is regulated to both 5V and 3.3V on the shield. The Host Shield takes its power from the ‘Vin’ pin on your Arduino. This shield adds USB Host capabilities to popular Arduino platform. A USB type A female connector is wired up to the IC, and it also supplies 5V as any normal USB port would. I got my VDIP1 USB Host controller from Saelig today and was able to get it hooked up and reading a Flash drive in a couple hours. The USB Host Shield contains all of the digital logic and analog circuit necessary to implement a full-speed USB peripheral/host controller with Arduino.
