Do send a trace without your fix.

Ok, that's a whole separate issue. There's linking but in jni (I
think). I filed a bug report and fixed it in my lib.
Also, I think I found another bug though I haven't filed a bug report
yet. I compiled kernel 2.4.30 and it seems they fixed interrupt/bulk
situation. I had to change a line in JavaxUsbKernel.c file to:
#define INTERRUPT_USES_BULK_LAST_KERNEL_VERSION KERNEL_VERSION(2,4,29)
Until I done that, I kept getting -22 response on any submit.
Ok, now to the original issue. I'm enclosing a trace. It created using
the "fix" I applied. If I don't apply the fix, I just creates
NullPointer on the active configuration and the devices never shows up
to begin with. But if you want, I can comment out my changes and send
you another trace. BTW, it is possible that this active configuration
issue has something to do with 2.4.30 - I never tried it with other
versions as I had to recompile the kernel to enable usb file system and
I updated to 2.4.30 at the same time.

Looking at it, I noticed the error was caused by my APC UPS not
returning a
valid configuration. The active config number returned was 98. It
seems that it
being set correctly, but getAcitiveUsbConfiguration() returns null.
This is how
I fixed it for myself:
UsbConfiguration usbConfig = device.getActiveUsbConfiguration();
if (usbConfig == null)
return;
//Iterator interfaces =
device.getActiveUsbConfiguration().getUsbInterfaces().iterator();
Iterator interfaces = usbConfig.getUsbInterfaces().iterator();
I'm not sure what's the best way to deal with it since it's the first
day I'm
using javax.usb or anything usb.
