I think, the device has a name of Manufactory,
with a "usbview" program (not in Java) from www.usbview.sourceforge.net
I can see the Manufactory: KOBIL(exact what i use).
like you said, debug shows the Exception is throwed here when getLangId():
if (4 > len || 4 > UsbUtil.unsignedInt(data[0]))
throw new UsbException("Strings not supported by device");

i have tryed IBMJava2-1.3, unfortunately it also doesn't run:
//---ErrorMsg---
/Exception in thread "main" java.lang.UnsupportedClassVersionError:
com/ibm/jusb/tools/swing/SwingUsbView (Unsupported major.minor
version 48.0)
at java.lang.ClassLoader.defineClass(ClassLoader.java:496)...
//----------------
but does not matter, i learn from it, and test in my simple Program.
I have still another Problem, when i insert another Device, a Camera or a
Zip, my test
program is immediately down. log shows:
//---Log----
/An unexpected exception has been detected in native code outside the VM.
/Unexpected Signal : 11 occurred at PC=0x400B7C1D

//---End of Log--------------
is it from USB-hotplug of Linux?
it is very comically, when i insert the Device before Linux-boot, it' ok,
but sometimes when i take it off, and insert once again, Linux notic it no
more:(
and device obtain also no energy! i must reboot linux, this is simply
irritating :(((
have you also experience this?
Tija, thank you once more
and wish you still a gut week end!
Chuan
