Since you wish to receive 64 bytes and an extra byte is coming in, have you
tried requesting 65 bytes?
Just my 2 cents worth.

Well, it is a full serial port. In fact if you really do just want to use it as
a serial port then I recommend you forget the mouse interface and just use it
directly as a serial port. Your life will be much simpler.

I think your best bet is to get one a usb to serial adapter (for example:
http://sewelldirect.com/usbtoserial.asp)
This will simply show up as a serial port and you won't have to do anything
differently than you do now.

Thank you for your help Dan. The problem turned out to be caused by the
version of java that was being run. There was a confusion of different
runtime environments.

Is there a pre-compiled 64 bit version of the libraries available? The
standard release does not work under 64 bit Linux.

Hi,
I often see it recommended, on this list, to build the libraries from
the latest cvs sources.
Well, I checked out the source files using cvs, but I am not sure what
all the steps are, or what else may be required, to perform a complete
build. I looked for FAQ or examples on the jsr-80 pages.
Hi,
I wrote an application that uses javax.usb to communicate with various
usb devices.Currently I am running it under Suse 10.0.
I know that in order for my Java program to be able to see a device
(much less talk to it) the permissions have to be appropriately set.
For some reason I have been
Here is an abbreviated example. Note that I have removed from this, all
checks, error handling, and such.
It is just the logic of creating two pipes for two endpoints. One IN and
one OUT. Then using them to do a write and a read.
It assumes that endpoint 2 is an OUT and endpoint 4 is an IN.
Note
You can only open one pipe on a given endpoint. That pipe has to be either an
IN or an OUT, depending on how that endpoint is defined. To do IN and OUT, you
need to separate endpoints.

javax.usb works great for me, but what I am missing is the magic formula to
automatically call my 'fxload' script to load firmware into the usb device. I
can load it manually and that works fine.
I have tried various approaches mainly centered around adding a line to
"/etc/hotplug/usb.usermap"
