Hi,
first of all: I repoduced the illegal byte sequence error with a 64-byte buffer. This
error comes only if I submit the buffer AFTER the output request,
the data comes first after I wait a while and only then I turn OFF the camera because
the program hangs (and I'm to lazy to kill the java process).
So FIRST after this the strange data and error comes in:

If I here exaggerate and wait 2s, I see on my messages:
Jun 13 13:51:27 Benjamin kernel: hub.c: USB new device connect on bus1/2, assigned
device number 10
Jun 13 13:51:27 Benjamin kernel: usb.c: USB device 10 (vend/prod 0x5ca/0x2201) is not
claimed by any active driver.
Jun 13 13:51:36 Benjamin kernel: usbdevfs: process 5310 (java) did not claim interface
0 before use
This way I see that the "did not claim"-error comes only for the input pipe.
(heres the rest)

and here the programms hangs. Sometimes its possible to kill it with [CTRL]+[C],
sometimes not.
So the solution must be somethere else, and I don't exclude a bug either in javaxusb
or in the kernel.
I can try the 2.5 series, I heard there is much done on the usb-task.
Another possibility is, that the device really sends nothing out at this time
and I must do something before, like a null-byte packet to the other bulk-out-endpoint.
Perhaps you see something of that sort in the usblog.
