Hello I try to make a MP3 driver base on Usb-skeleton file for the Mpgio mp3 player
actually me and a friend have sniffed the mp3 player on Windows with usb snoopy pro, it work fine , having a good log (I can send you if you want) but the big problem is about the reverse engine when we send control msg with my C program the usb mpgio doesn't respond and we don't know where is the problem 1/ must i reset the usb port before sending a request and how ?? 2/ must i take the request (usb_control_msg) orderer of snoopy pro for initialise my player and use it. 3/ have you tips for translating an usbsnoopy log for linux program (such as the lego tower project) 4/in my program I think all is good (hehe, sometimes I dream.. ;-)) but the Mpgio hardware doesn't respond to the driver : perhaps the problem is due to : -hardware initilisation failed -order of request (C2 00 00 00 00 00 03 ...) if you can sending me doc or informations about making this special usb control msg or other usb initialisation :) Best Regards, Olivier and Remy ps : his midi project : www.sf.net/projects/portmanlinux (ok, totally O/T, but he insist..) Please CC : [EMAIL PROTECTED] [EMAIL PROTECTED] PS : a part of the log 00000000 16:25:51 00000001 16:25:51 <<<<<<< URB 1201 coming back... 00000002 16:25:51 -- URB_FUNCTION_CONTROL_TRANSFER: 00000003 16:25:51 PipeHandle = 815d0fb4 00000004 16:25:51 TransferFlags = 00000002 (USBD_TRANSFER_DIRECTION_OUT, USBD_SHORT_TRANSFER_OK) 00000005 16:25:51 TransferBufferLength = 00000000 00000006 16:25:51 TransferBuffer = 81371351 00000007 16:25:51 TransferBufferMDL = 00000000 00000008 16:25:51 UrbLink = 00000000 00000009 16:25:51 SetupPacket : 42 04 06 01 00 00 00 00 00000010 16:25:51 UsbSnoop -
