Re: Need Help: CE5.0 flash is not shown as USB mass storage device

Did you change the "platform.reg" and "*.bib" files under your project
release directory? Check the reginit.ini file whethe there is
"DefaultClientDriver"="Mass_Storage_Class" in it .

If you change the "platform.reg" through the PlatformBulder IDE TAB, it
does't work until you sysgen the whole project.

Hi Bruce,
In my build serialusbfn.dll is not included. When i connect the device,
wceusbsh.sys is getting loaded and in the device manager i could see it as
windows ce devices. Once i enable, still active sync works. It seems the
OS
always tries to load wceusbsh.sys for my device. Please give me your
inputs.

Hi Bruce,
Thanks for the reply. Even though i made the usb mass storage function
driver usbmsfn.dll as the default client driver, whenever i connect the
CE5.0
terminal to the PC, only usb serial function driver is getting loaded.
I
have
enabled the debug info in BOT.cpp and block.cpp and am not getting any
debug
messages from those files which tells me that usbmsfn.dll is not at
getting
loaded.
I believe excluding serialusbfn.dll from the image is sufficient.
Please let me know your inputs regarding this.

Modified to be a bus agnostic driver, or modified to just work on CE

There is a big difference.

Do you have the serialusbfn.dll in your build? If you remove it does
ActiveSync still work?

Hi Bruce,
Thanks for your reply. Yes we have the USBFN driver which was
derived
from
CE4.2 and modified according to CE5.0 USB function driver
requirements.
USB active sync works fine without any problem. usbmsfn.dll is
present
in
the release directory. But this dll does not seem to be loaded.
Awaiting your reply.

Hi All,
I am trying to expose my flash folders as a USB mass storage
device.
Added SYSGEN_USBFN_STORAGE catalog item and added following
regisry.
settings to my platform.reg:
[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers]
"DefaultClientDriver"=- ; erase previous default
[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers]
"DefaultClientDriver"="Mass_Storage_Class"

[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers\Mass_Storage_Class]
"Dll"="usbmsfn.dll"
"InterfaceSubClass"=dword:06
"InterfaceProtocol"=dword:50
"DeviceName"="DSK1:"
"FriendlyName"="Mass Storage"
"idVendor"=dword:045E
"Manufacturer"="Generic Manufacturer (PROTOTYPE--Remember to
change
idVendor)"
"idProduct"=dword:FFFF
"Product"="Generic Mass Storage (PROTOTYPE--Remember to change
idVendor)"
"bcdDevice"=dword:0
But still if i connect my ce5.0 device(active sync disabled), it
is
getting
recognized as "Windows CE devices" and not as a mass storage
device.
If
i
enable active sync, it works with USB.
When i check with Remote Process viewer, i could not see the
usbmsfn.dll.
I checked the device names using storage manager application and
in
the
registry too. The name is DSK1,DSK2 for platform&application and
DSK3
is
for
SD cards.
I am not sure, whether i need to make any code changes in USBFN
driver
to
show my flash folders as a SUSB mass storage device.

Could anyone please tell me what are changes we need to make to
show
as
terminal's flash as USB storage device?

Please give me your valuable inputs. I appreciate your help in
advance.

Thanks
Saravana
