usb modem driver install very slowly

NTDEV

Dear all
Our usb modem driver installation is very slow, the last window is copy sys file. This window will keep in serveral minutes, but usb modem device is ok at this time.
how to reduce the installation time?

thank you very much.

At device installation time, the Modem class installer will issue ATE0Q0V1 to your device and wait for the “OK” to return. I think it might do another command too (maybe AT+FCLASS=?), but it escapes me at the moment. Both strings are hard-coded into modemui.dll, they’re sent no matter what and you can’t remove them.

Does your device support these commands and respond properly? (either “OK” or “ERROR”) Are you handling all these IRPs correctly at device installation time? If not, the installer will hang…

Hi Chris,
I have capture the log. The first at command is ATZQ0E0V1 and our device return “OK”,
The second command is AT+GCI?, our device return “error”. I think it should be ok.
But the installer is still hang.

why

than you very much for your help.

Oh yeah, AT+GCI?. Anyway, my devices all say ERROR to that command too, but I don’t have this problem, so that can’t be it (i.e. you must respond “OK”).

If the installer is hanging, my best guess is that you are either losing IRPs somewhere (i.e. not supporting cancellation/IRP queueing properly) or you’ve misimplemented the serial spec in some way (either the timeout semantics, or the serial IOCTLs).

It’s hard to give a better guess than that based on the information you’ve given. Do you have a full dump of all the I/O calls into your driver, including your responses?

I received read IRP with length 4096 bytes, after receiving “error”. Then I timeouted this IRP with data “error”. Then clean up is called,then close is called.
Then I haven’t received any IOCTLs.

but the installation was still hanging.
