Hi all, Bit of a newbie here. Im looking for some help on writting a Java driver for my DRU-R100 DLink USB Radio. I have used USB Snoopy in order to capture the data when I turn the radio on and turn it off but am having problems in recreating those actions using the Java USB API.
Im pretty sure that I have everything right up to the point of sending data to the device. I am at the point where I have an open pipe and am now trying to send a byte[] in the means of a syncSubmit call. USB Snoopy reports that there is 1 interface and 1 pipe, which seems to be a direction in, transfer type interrupt. The very first thing that snoopy logs when I run the radio application is shown below. What im unsure of is what information in the Snoopy output do I use to send this (what I believe is) radio on command to the USB device? Do i use the SetupPacket data in a byte[] and send that using syncSubmit or am I looking at it in the wrong way? Any help would be great, thank you. 00000000 0.00000000 UsbSnoop - IRP_MJ_CREATE 00000001 0.00002067 UsbSnoop - IRP_MJ_INTERNAL_DEVICE_CONTROL, IOCTL_INTERNAL_USB_SUBMIT_URB 00000002 0.00002542 00000003 0.00002626 >>>>>>> URB 4 going down... 00000004 0.00003045 -- URB_FUNCTION_VENDOR_DEVICE: 00000005 0.00003604 TransferFlags = 00000001 (USBD_TRANSFER_DIRECTION_IN, ~USBD_SHORT_TRANSFER_OK) 00000006 0.00004051 TransferBufferLength = 00000008 00000007 0.00004442 TransferBuffer = 81b87fb4 00000008 0.00004749 TransferBufferMDL = 00000000 00000009 0.00005168 UrbLink = 00000000 00000010 0.00005476 RequestTypeReservedBits = 00 00000011 0.00005783 Request = 00 00000012 0.00006090 Value = 00fc 00000013 0.00006425 Index = 0012 00000014 0.00456455 00000015 0.00456538 <<<<<<< URB 4 coming back... 00000016 0.00457069 -- URB_FUNCTION_CONTROL_TRANSFER: 00000017 0.00457516 PipeHandle = 81ae0154 00000018 0.00458047 TransferFlags = 00000003 (USBD_TRANSFER_DIRECTION_IN, USBD_SHORT_TRANSFER_OK) 00000019 0.00458438 TransferBufferLength = 00000001 00000020 0.00458829 TransferBuffer = 81b87fb4 00000021 0.00459220 TransferBufferMDL = 81b4d328 00000022 0.00459500 00000023 0.00459835 0000: ff 00000024 0.00460114 UrbLink = 00000000 00000025 0.00461679 SetupPacket : c0 00 fc 00 12 00 08 00 00000026 0.00462908 UsbSnoop - IRP_MJ_CLOSE ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
