NO RESPONSE from QUALCOMM MDM9200 based chip set on NDIS interface

[davidpreetham]

hello dear all,

Is there any difference in xp, vista and windows 7 operating systems regarding. control requests over control pipe.? we have developed drivers for ndis port miniport NDIS driver.

its working fine with LTE network in XP and vista. but in case of windows 7 operating systems. when we send control request to stop network to device, we are not getting response from device. we have observed Lecroys usb analyzer logs. we are not getting response. even though we its device side problem. why this issue is not happening in xp and vista.
we have two applications for sending control requests to device for starting network.
1) company application.
2) mobile broad band Microsoft provided default application .

this issue happens only with company application. we have compared data in requests send by cm and mobile broadband but no difference.. please guide us its an urgent issue

Thanks for reply..
This is helpful document. we have used all those tools. we are near to commercialization of product. But only issue its modem device with NDIS interface. everything working fine with 3G network. problem is when we use modem device NTT docomo LTE network and we used the NDIS interface for the network connection. after browsing for some if we disconnect using connection manager it is not disconnecting. From device side we are getting response. but this issue is not happening in vista and xp. yes the only difference between data transfer is mediatype in windows 7 and vista and xp.
please help we if you people required any information please ask me
