in com.ibm.jusb.UsbOperationsImp.setInterface /*correct*/ Request request = getRequestImpFactory().createSetInterfaceRequest(wValue, wIndex);
/*incorrect*/ Request request = getRequestImpFactory().createSetInterfaceRequest( wIndex, wValue ); With this change Roger's code to set alternate setting is working fine. Interfaces of UsbOperations are a bit inconsistent with the order of wIndex and wValue. Both parameters have same type and easy to mess them up, this probably caused the bug. It'll be good to stick to a fixed wIndex / wValue order in the new API.
