How can I make use of the USB-port from Java ?

[Arne Styve]

Hi,

I am curretly looking into a project where a USB-port is to be used, but I
cannot find any implemented Java API's for USB to use on the Windows
platform. I would be very greatful to get som hints about good USB API
implementations out there.

Any help appreciated.

Did you try http://javax-usb.org/

Hi Thomas,

Yes, I looked at it, but it's for Linux only. As it says on the web-page:
javax-usb-ri-windows : This is a pre-alpha Windows implementation (it does
not work, it needs a kernel driver).

What about http://www.steelbrothers.ch/jusb/ ?

And if that doesn't work, how about listing the ones you tried so we
don't waste our times recommending stuff that you know won't work for you?

How about compiling and running the linux implementation over Cygwin? Is it
possible?

hello,
try with the java's comm api to access the usb access.

Hi Oliver,

Please do not let me waste your time. Searching the internet I can manage on
my own. I was hoping to find someone on this newsgroup that had experience
with developing solutions in Java using the USB-port and hence could
recommend a suitable library. Sorry if my initial question was not clear
enough in that respect.

Anyway, thanks for your tip. I looked at it (on your recomendation), but it
seams to be quite prototypish and incomplete ( An implementation attempt to
provide jUSB for Windows 2000/XP as it says on the website).

Thanks for the tip. But isn't CygWin "just" a way to get some Unix/Linux
commands/tools on the windows platform ? You still have to rebuild the
applications froms sourcecode for the Windows platform, I beleive, and hence
you will need specific Windows drivers for the USB-port, probably.

I'll chekc into it a bit further.

Thanks !

Hi,

The Java comm API does not support USB, and as far as I have been able to
find out, there are no concrete plans to include USB either.

Hi!

Problem solved (well, partly). Got a tip from the Norwgian newsgroup
(no.it.programmering.java) about a recent article:
http://today.java.net/pub/a/today/2006/07/06/java-and-usb.html?page=1 about
Java and USB.
Also found a commercial library (from the same article) that I might try
out: http://www.icaste.com/jcommusb.htm

Thanks for trying to help me out here

Why on earth does that require the .NET runtime ?

(Only a rhetorical question ;-)

(And I'm not wildy impressed by per-seat licencing for a programming library
either...)

It sounds like you have a solution for you problem, but maybe no a
great one.

I was reading a book at the book store about Java's new IO Packages
(NIO) which gives you the ability to access USB ports.

I believe this is available for Java 1.4 and java 1.5 and is cross
platform.


perhaps a book also with examples. Please take a look at :
http://press.oreilly.com/pub/pr/1581

Best of Luck, Please post back when you have a known solution. You
would think this would be an easy questions, but I don't personally
know of anyone who has done anything with USB and java.

Hi Tony,

You're right, it's a solution, but not a very great one.

I'll check out the book. From the review of the book it looks promising, but
if the java.nio API covers USB, why doesn't it say so on the official
web-pages at Sun.....
Also found good support for USB on the SPARC-platform.....

I'll keep you updated, if I find a better solution to this.

Thanks for your inputs.

Regards Arne
