 USB msc+cdc compostie in win7 not work !!!

Dear all, my usb msc+cdc composite project work well in winxp ;but in win7,my cdc vcom could not recieve&send data;my cdc inf file is mchp_MSD_CDC.inf,is ok in win7,because cdc project also work well in win7.

when (win7) reinstall&uninstall vcom deriver in devicelist,pc requrie a long time.

 RE: USB msc+cdc compostie in win7 not work !!!

Really?

Microchip INF files for CDC don't follow these MS guideline of INF, even on the latest (v2.7) version of MCHPFSUSB stack (v2010-04-28).

1) Don't write LayoutFile on [Version] section.
2) Don't specify usbser.sys directly for CopyFiles
Instead, include mdmcpq.inf AND refer to FakeModemCopyFileSection

I've pointed out it on this topic of Microchip forum.
http://www.microchip.com/forums/tm.aspx?m=488342

Related MS documents are,
1) INF Version Section

LayoutFile
Note This entry is not supported in Windows Vista and later versions of Windows.

2) How to use or to reference the Usbser.sys driver from universal serial bus (USB) modem .inf files

I use win7-32bit mode

 RE: USB msc+cdc compostie in win7 not work !!!

thank you, Tsuneo Chinzei!
I use mchp_MSD_CDC.inf(v2.7) file in win7,cdc project is really ok,but msc+cdc compostie project is bad.

 RE: USB msc+cdc compostie in win7 not work !!!

Tsuneo,
Did you test cdc+msc composite device in win7?

 RE: USB msc+cdc compostie in win7 not work !!!

when i plug my cdc+msc on win7,and update cdc deriver in devicelist,select the inf file,install.....pc is always in installing stae.
my cdc+msc composite problem in win7,maybe is nothing with inf file;
Tsuneo,
did you test cdc+msc composite device in win7?

thank you very much!

In this weekend, at last, I got enough spare time to test this issue ;-)

Made a MSC + (IAD) CDC composite device on Keil MCB2300 board.
Just merged Keil Examples (USBMem and USBCDC) together in quick and dirty way.

Here is the test code link
http://www.8052.com/users/Notus/MCB2300_MSC_CDC.zip

And tested on these Windows versions

Result

Windows XP (x86) SP3 - success
Windows XP (x64) SP2 - installation success, but driver failed to start in Code 10
Because of old drivers
- usbccgp.sys 5.2.3790.3959, Feb 18, 2007
- usbser.sys 5.2.3790.1830, March 24, 2005

Vista (x86) SP2 - success
Vista (x64) SP2 - success

Windows 7 (x86) - success
Windows 7 (x64) - success

Here is a revised INF file for this test
This single INF works for both of x86/x64 on all Windows version (XP, Vista and 7)
The original USBCDC example is also supported.

Enjoy!

 RE: USB msc+cdc compostie in win7 not work !!!

thank you,Tsuneo.
I wil test it.
thank you,again.

 RE: USB msc+cdc compostie in win7 not work !!!

Hi Tsuneo,
Thanks for your USB composite example, it works well. If you can put the mcb2300-vcom.inf (Revised) inf file into the USBMSC disk, it will be more interesting.
