[LabJack Support]

As you probably already know, we provide the UD Driver on Windows (http://labjack.com/support/ud/ud-setup) and the Exodriver on Mac and Linux (http://labjack.com/support/linux-and-mac-os-x-drivers). The Exodriver is user-level C code that depends on libusb (also user-level C), so looking at that source may help you.

First, you need to ask some fundamental questions about the capabilities of your operating system. The most important question is does it support USB host operations? If it does, you're in business. If not, you'll have to get that working first.

Now, to answer your questions:

Is there some documentation for reading offline?

We don't have any documentation about how to write your own driver, but we do give you everything you need to know. In the case of the U3, you're going to want to grab a copy of the User's Guide PDF (http://labjack.com/support/u3/users-guide) as well as the updated version of section five with can be downloaded as a PDF (http://labjack.com/printpdf/book/export/html/402).

Section 2.1 of the User's Guide has all the details about USB you need. This section is important for figuring out which devices are LabJacks, and which endpoints to direct your bulk transfers.

After you get a USB open, write, read, and close, you are ready to work with section five of the User's Guide. This section describes the bytes needed to be written to a device, and what to expect back from the read.

how much money [and] time it cost to buy one U3 from spain?
