Everything is fine, i've opened the IN Endpoint using the UsbPipe and access it the following way: currentDui = new DefaultUsbIrp(buffer); currentDui = new DefaultUsbIrp(buffer); currentDui.setAcceptShortPacket(true); usbScannerPipe.syncSubmit(currentDui);I receive the data i'm expecting and everything works fine UNTIL i want to abort and cancel everything: usbScannerPipe.abortAllSubmissions(); usbScannerPipe.close(); usbScannerPipe = null; usbScannerInterface.release(); usbScannerInterface = null;The problem is that syncSubmit immediately synchronizes using "submitLock" (UsbPipeImp). After that the whole thing just keeps blocking while waiting for data. When i call abortAllSubmissions from another Thread, it too locks on "submitLock", waiting for the submitSync method to release this lock. IF i scan another Barcode, the syncSubmit method returns and everything is fine, otherwise it's a perfect deadlock.What's the correct work-flow here? how can i cancel everything pending and close the pipe and interface?i'm using Ubuntu 10.04, and java-usb 1.0.1Thanks in advanceKlaus Gradinger > > ------------------------------------------------------------------------------ > The Next 800 Companies to Lead America's Growth: New Video Whitepaper > David G.
