[javax-usb-devel] Help - Error submitting IRP : Submission aborted

[Jenks, Robert]

I need some pointers…   I’m trying to use javax-usb for the first time and I’m running into a brick wall.  I’m trying to talk to a new device we’re building.   Here is the flow:   I am able to traverse the USB device lists and find our new device by it’s VendorID/ProductID. I set configuration 0 (this works fine) I get the list of interfaces and only find 1 (which is correct) I claim interface 1 I am able to determine that interface 1 has two endpoints (one bulk IN and one bulk OUT) I am able to open a pipe on endpoint 2 (OUT) I create an IRP with a size of 32 (MaxPacketSize is 64)  new DefaultUsbIrp(new byte[] {…}); I then call pipe.syncSubmit(irp)     LOG:[xfer](4) JavaxUsbPipeRequest.c.pipe_request[63] Submitting URB bulk_pipe_request : URB endpoint = 2 bulk_pipe_request : URB status = 0 bulk_pipe_request : URB signal = 0 bulk_pipe_request : URB buffer length = 32 bulk_pipe_request : URB actual length = 0 bulk_pipe_request : URB data = ""> LOG:[xfer](1) JavaxUsbPipeRequest.c.pipe_request[74] Could not submit URB (errno -2) LOG:[xfer](4) JavaxUsbDeviceProxy.c.Java_com_ibm_jusb_os_linux_JavaxUsb_nativeDeviceProxy[78] Completed Request javax.usb.UsbException: Error submitting IRP : Submission aborted             at com.ibm.jusb.os.linux.LinuxPipeRequest.completeUsbIrp(LinuxPipeRequest.java:84)             at com.ibm.jusb.os.linux.LinuxPipeRequest.setCompleted(LinuxPipeRequest.java:74)             …   Any ideas???   -Robert
