WinCE modifications Serial_class to USBser class
in [Device Drivers]
|
From: HimaNshu on 10 Sep 2006 20:33 I appreciate your last suggestion, but I cannot change my platform to Win CE 6 or WinCE mobile 5.0 and even I don't have that much time to wait for Win CE 6, I know that there is no any other option other then waiting for Win CE 6.0 but I want to write my own USB Modem driver for usbser.sys support. for that I just want to know what are the basic requirements to be implement after establishing connection, because I am passing correct descriptor so device is connecting properly but at Host end I unable to configure port so my HyperTerminal test is not working until I handling mandatory requests from Host side to device like, ET_LINE_CODING SEND_ENCAPSULATED_COMMAND SET_CONTROL_LINE_STATE SEND_BREAK GET_LINE_CODING GET_ENCAPSULATED_RESPONSE so would like to know, is there any request handling implemented in serial_class code(usbfndrv.cpp or in PDD layer)? if yes then let me know where is it exactly? and answer is No then please suggest me how I can implement it and which are mandatory out of them.

From: HimaNshu on 11 Sep 2006 05:40 I have impliment just cases with this requestes SET_LINE_CODING SEND_ENCAPSULATED_COMMAND SET_CONTROL_LINE_STATE SEND_BREAK GET_LINE_CODING GET_ENCAPSULATED_RESPONSE It working fine in connection and even comport is opening properly at Host end also...it sends SET_LINE_CODING request... CONTROL_RESPONSE CUsbFn::HandleClassRequest( USB_DEVICE_REQUEST udr ) { CONTROL_RESPONSE response = CR_STALL_DEFAULT_PIPE;//CR_SUCCESS_SEND_CONTROL_HANDSHAKE; memset(strLogString, 0, 256); sprintf(strLogString, "HandleClassRequest USB_DEVICE_REQUEST udr.bmReqTyp = 0x%X, udr.bRequest = 0x%X, udr.wValue = %d, udr.wIndex = %d, udr.wLength = %d",udr.bmRequestType, udr.bRequest, udr.wValue, udr.wIndex, udr.wLength); USB_LOG("****************************"); USB_LOG(strLogString); if (udr.bmRequestType == (USB_REQUEST_CLASS | USB_REQUEST_FOR_INTERFACE | USB_REQUEST_HOST_TO_DEVICE) ) { switch(udr.bRequest) { case SET_CONTROL_LINE_STATE: { /* Host is notifying us of control line state. * wValue contains bitmask * 0 - DTR * 1 - RTS */ DEBUGMSG( ZONE_FUNCTION, (TEXT("SET_CONTROL_LINE_STATE %X\r\n"), udr.wValue)); DWORD dwModemStatus = 0; if (udr.wValue & USB_COMM_DTR) dwModemStatus |= (MS_DSR_ON|MS_RLSD_ON); // DTR active, set DSR/RLSD if (udr.wValue & USB_COMM_RTS) dwModemStatus |= MS_CTS_ON; // RTS active, set CTS memset(strLogString, 0, 256); sprintf(strLogString, "HandleClassRequest USB_DEVICE_REQUEST USB_COMM_DTR = 0x%X, USB_COMM_RTS = 0x%X, udr.wValue = %d, dwModemStatus = 0x%X, MS_CTS_ON = 0x%X",USB_COMM_DTR, USB_COMM_RTS, udr.wValue, dwModemStatus, MS_CTS_ON); USB_LOG(strLogString); ModemSignal(dwModemStatus); response = CR_SUCCESS_SEND_CONTROL_HANDSHAKE; } break; case GET_ENCAPSULATED_RESPONSE: { USB_LOG("GET_ENCAPSULATED_RESPONSE"); response = CR_SUCCESS_SEND_CONTROL_HANDSHAKE; } break; case SEND_ENCAPSULATED_COMMAND: { USB_LOG("SEND_ENCAPSULATED_COMMAND"); response = CR_SUCCESS_SEND_CONTROL_HANDSHAKE; } break; case SET_LINE_CODING: { USB_LOG("SET_LINE_CODING"); response = CR_SUCCESS_SEND_CONTROL_HANDSHAKE; } break; case GET_LINE_CODING: { USB_LOG("GET_LINE_CODING"); } break; case SEND_BREAK: { USB_LOG("SEND_BREAK"); response = CR_SUCCESS_SEND_CONTROL_HANDSHAKE; } break; } } else { RETAILMSG(1, (_T("Unrecognized Serial class bRequest -> 0x%X\r\n"), udr.bmRequestType)); USB_LOG("Unrecognized Serial class bRequest"); ASSERT(FALSE); } ASSERT(response == CR_SUCCESS_SEND_CONTROL_HANDSHAKE); return response; } but now one problem is there when I am transmiting some data from device to Host it follows below functions and does not come out it hungs somewhere and even at Host end when I am trying to transmite data from Hyper terminal then it is also not received at device end... when I call WriteFile() it follows below functions.... ********************************* USBSerialFn::CancelReceive USBSerialFn::XmitInterruptHandler CUsbFuncPipe::WriteData CUsbFuncPipe::WriteDataOnce CUsbFuncTransfer::CloseTransfer CUsbFuncTransfer::IssueTransfer CUsbFuncPipe::WriteDataOnce CUsbFuncTransfer::CloseTransfer *********************************************** all three pipe are also opening properly... anybody can give some idea to move further with Wirting data....
