Hello,
I am trying to submit a control IRP packet to an USB device (UsbDevice.
asyncSubmit(UsbControlIrp irp)) and I get the following Exception:
javax.usb.UsbException: Error submitting IRP : Device or resource busy
at
com.ibm.jusb.os.linux.LinuxPipeRequest.completeUsbIrp(LinuxPipeRequest.j
ava:84)
at
com.ibm.jusb.os.linux.LinuxPipeRequest.setCompleted(LinuxPipeRequest.jav
a:74)
at com.ibm.jusb.os.linux.JavaxUsb.nativeDeviceProxy(Native
Method)
at
com.ibm.jusb.os.linux.LinuxDeviceProxy$1.run(LinuxDeviceProxy.java:87)
at java.lang.Thread.run(Thread.java:536)
My question:
I assume the problem is because Linux loads an USB driver for this
device (keyboard driver). Is that true or is there some other issue to
this problem? If it is true, how can I remove the driver?
Thank you very much and kind regards,
Tomaz
My code:
//I search for my USB device and put it into this.m_udDevice
//create control IRP
UsbControlIrp uciSetDescriptorRequest =
this.m_udDevice.createUsbControlIrp(
(byte) 0x21,
(byte) 0x09,
(short) 0x0300,
(short) 0x0000);
uciSetDescriptorRequest.setData(new byte[] {0x02});
//submit control IRP
try
{
this.m_udDevice.syncSubmit(uciSetDescriptorRequest);
//exception is thrown in above method
}
catch (IllegalArgumentException ex)
{
ex.printStackTrace();
}
catch (UsbException ex)
{
ex.printStackTrace();
}
