Hi @ all I am new at this mailing list and my English + Java Knowledge are not the best ;) (plz keep patient)
So I use the JSR80 - API (thx god for this peace Software *G*) + I got from Garmin this Specification of the Garmin Protocol http://www8.garmin.com/support/commProtocol.html I only want to send/recieve Data to/from the Device (Garmin eTrex Vista). With the help of this Code, I can figured out which Devices and Hubs are connected to my PC. ************************************************************ public class USBLister{ public USBLister() { UsbServices services; try { services = UsbHostManager.getUsbServices(); UsbHub vroothub = services.getRootUsbHub(); String s=vroothub.toString(); System.out.println(s); listDevices(vroothub); } catch (SecurityException e) { e.printStackTrace(); } catch (UsbException e) { e.printStackTrace(); } } public void listDevices(UsbHub hub){ List Devices = hub.getAttachedUsbDevices(); Iterator iterator = Devices.iterator(); while (iterator.hasNext()) { UsbDevice device = (UsbDevice) iterator.next(); if (device.isUsbHub()) { System.out.println("HUB: "+ device); listDevices((UsbHub) device); }else{ System.out.println("Device: "+ device); try{ UsbDeviceDescriptor descriptor = device.getUsbDeviceDescriptor(); //Id Vendor - später um es zu identifizieren System.out.println("IdVendor: "+descriptor.idVendor()); System.out.println("IdProduct: "+descriptor.idProduct()); }catch(Exception ex){} } } } } Can anyone give me a Tipp how to speak with the Device ? I used this Code: public void IODevices(UsbDevice device){ try{ UsbConfiguration config = device.getActiveUsbConfiguration(); List totalInterfaces = config.getUsbInterfaces(); for (int i=0; i<totalInterfaces.size(); i++){ UsbInterface interf = (UsbInterface) totalInterfaces.get(i); interf.claim(new UsbInterfacePolicy() { public boolean forceClaim(UsbInterface usbInterface) { return true; } }); List totalEndpoints = interf.getUsbEndpoints(); for (int j = 0; j < totalEndpoints.size(); j++){ UsbEndpoint ep = (UsbEndpoint) totalEndpoints.get(j); System.out.println(j); System.out.println("***********************************"); System.out.println("Direction: "+ep.getDirection()); System.out.println("Descriptor: "+ep.getUsbEndpointDescriptor()); System.out.println("Type: "+ep.getType()); System.out.println("***********************************"); } } } How to figure out which is the Bulk In or Bulk out ? My Output is this one: [EMAIL PROTECTED] HUB: [EMAIL PROTECTED] HUB: [EMAIL PROTECTED] HUB: [EMAIL PROTECTED] Device: [EMAIL PROTECTED] 0 *********************************** Direction: -128 Descriptor: bLength : 7 bDescriptorType : 0x05 bEndpointAddress : 0x81 bmAttributes : 0x02 wMaxPacketSize : 64 bInterval : 0 Type: 2 *********************************** 1 *********************************** Direction: -128 Descriptor: bLength : 7 bDescriptorType : 0x05 bEndpointAddress : 0x82 bmAttributes : 0x03 wMaxPacketSize : 64 bInterval : 1 Type: 3 *********************************** 2 *********************************** Direction: 0 Descriptor: bLength : 7 bDescriptorType : 0x05 bEndpointAddress : 0x03 bmAttributes : 0x02 wMaxPacketSize : 64 bInterval : 0 Type: 2 *********************************** IdVendor: 2334 IdProduct: 3 HUB: [EMAIL PROTECTED] HUB: [EMAIL PROTECTED] HUB: [EMAIL PROTECTED] --------------------------------------------------- Thx for every tipp ;) greets uter ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
