# Datasheet doesn't include pinout info?

I am trying to connect arduino and usb lancard

In the datasheet, there is USB transceiver interface, containing symbol, type, pin number, description (usb D+ or D- signal).

However, the datasheet (about 20 pages) includes no information about what pin (out of 4) and what value to send to make anything work.

What reference should I refer to?

Thanks!

(I am a hardware beginner, sorry for dumb question)

• its clear that English isn't your first language but your going to have to do some work to make this question answerable. – Mark Jun 2 '11 at 1:38
• oh thank you for your advice. could you be more specify? such as 3rd sentence's grammar is broken or something like that. thanks! – kim taeyun Jun 2 '11 at 1:48
• from my experience, if the datasheet doesn't have enough info to make it work then you should look for a different part. – Kellenjb Jun 2 '11 at 2:12
• Are you talking about the datasheet for your lancard, or for the arduino? If it's the lancard, do you have a part number for it? – Jeremy Kerr Jun 2 '11 at 2:56
• As I said in one of my previous comments, you'll need a card that can work with Arduino out of the box. If such cards aren't available in your area, you could try making one. You'll need a chip that's stand-alone or uses one of the popular microcontroller protocols such SPI or $I^{2}C$. – AndrejaKo Jun 2 '11 at 7:19
