Dan, Here is the info you requested.
You downloaded the properties file but java still can't find it? That is correct. What does "echo $CLASSPATH" show? [EMAIL PROTECTED]:/TestShare/FindUsbDevice/src/findusbdevice# echo $classpath /opt/javax-usb/lib:/opt/javax-usb/etc/javax.usb.prperties What directory is the properties file in? [EMAIL PROTECTED]:/opt/javax-usb/etc# dir javax.usb.properties Where did you get the properties file? http://downloads.sourceforge.net/javax-usb/javax-usb-1.0.1-1.i386.rpm?modtime=1135006365&big_mirror=0 What is the contents of the properties file? # # Properties file for javax.usb # # This file is provided by the Linux implementation of javax.usb. # # The 2.4 kernel does not support control-type queueing nor interrupt-type # queueing (see below to enable javax.usb internal queueing). # # Some 2.4 kernels do not properly handle hotplug notification, specifically # those somewhere after 2.4.19. See below to enable polling instead. # ################################################################################ # Properties required/used by javax.usb API ################################################################################ # This is required by the API, this is the class that the API will create # to implement UsbServices. javax.usb.services = com.ibm.jusb.os.linux.LinuxUsbServices ################################################################################ # Properties required/used by javax.usb Common Reference Implementation ################################################################################ # These properties enable queueing for different pipe types. If the operating # system does not support queueing for a particular pipe type (or at all), # enable queueing here. This queueing is most likely much slower than OS-level # queueing, so if the OS supports queueing, these should not be enabled. com.ibm.jusb.UsbPipeImp.queueSubmissions.control = true #com.ibm.jusb.UsbPipeImp.queueSubmissions.interrupt = false #com.ibm.jusb.UsbPipeImp.queueSubmissions.isochronous = false #com.ibm.jusb.UsbPipeImp.queueSubmissions.bulk = false # This property is similar to the UsbPipe-specific queueing properties, but # this applies only to the Default Control Pipe queueing. com.ibm.jusb.UsbDeviceImp.queueSubmissions = true ################################################################################ # Properties required/used by javax.usb Linux Implementation ################################################################################ # If polling should be used instead of waiting for a hotplug notification. # Some kernel versions have a bug, and don't update the device node(s) until # many seconds after waking up threads waiting on the devices file. # If you are not getting hotplug events on a moderately to heavily loaded system, # use polling. # Note that since the new (buggy?) kernel behavior breaks javax.usb, this defaults to true! # If you know your kernel isn't broken you can set this to false. #com.ibm.jusb.os.linux.LinuxUsbServices.topologyUpdateUsePolling = true # If polling is disabled, this is how long in ms to delay after a # hotplug event is signalled to re-enumerate the USB bus. # If polling is enabled, this is how often to poll. #com.ibm.jusb.os.linux.LinuxUsbServices.topologyUpdateDelay = 5000 # After new device(s) are detected, the device's driver is probably taking its # sweet time talking to them. This delay lets the Linux driver (if any) have some time to # talk before we send a device connection event, which may cause an application # to immediately start talking to the device. #com.ibm.jusb.os.linux.LinuxUsbServices.topologyUpdateNewDeviceDelay = 500 ################################################################################ # Tracing properties used by javax.usb Linux Implementation ################################################################################ # These rest apply to JNI tracing levels. This is a little better than it used to be, # but it needs more improvement as far as controlling the tracers and levels. # This either disables tracing entirely, or enables some amount of tracing. #com.ibm.jusb.os.linux.LinuxUsbServices.JNI.tracing = true # This defines where the JNI tracing output is sent. # The default is stderr. Note that if append mode is used, the trace file will # grow ever-larger every time javax.usb is run, and its size should be managed # somehow.
