Re: USB mass storage

Yes, you can change function class driver programatically -I've
explained how to do this several times on this group. Find the thread
"How to switch default usb client function driver on wince 5.0 at
runtime?" from march this year for example code.

I want to activesynce to a PC. but behave as a mass storage device when I
need to attach to a printer. Do you have any suggestions on how I should do
this?

Sorry, I re-read all of the posts and see that you are trying to get USBF
Mass Storage to work.

No, you can't have it both ways the device ether identifies itself as a Mass
Storage device, or a Serial device and the PC acts accordingly. The good
news is that if you are using ActiveSync then you can still access the
storage on the device.

I think that you have added the wrong USB Mass Storage. You seem to have
added the USBF mass storage, which causes your device to show up as a USB
Mass Storage device to the PC.

That is okay, but if you want ActiveSync then you need to set the default
client to be serial instead of mass storage.

I do not see my NOR drive show up in the registry under
[HKEY_LOCAL_MACHINE\Drivers\Active]
by using the remote registry (I know the NOR device works as I am saving
files to it) - I did this on a version without
the mass_storage_class since when I have it included I can no longer
active
sync.
Is there a way to have both Active sync and USB mass storage?
I do see my SD Card as DSK1. It was the only thing under the
Divers\Active
to have DSK in its name.
I tried changing the registry entries as shown below. Is there something
else I need to do?

There are several alternatives but on a running device you can search
for the block driver's device name in the registry under
[HKEY_LOCAL_MACHINE\Drivers\Active].

It's usually a good idea to specify indexes for the block drivers to
guarrantee the same index regardless of when it is loaded.

I think you have confused "Order" with "Index" in the registry
settings. You need to know the "Index" of the block device you want
to
expose. Either you figure out what index your block device is
assigned
and append that to the prefix, or you can force a specific index by
specifying "Index" in the registry. "Index"=dword:2 in the StrataFMD
registry settings should ensure it gets the device name "DSK2:".

Thanks for reply! I was not able to open your link or find the
document you
referred to Sameer. I have tried using the PB help, but without
success. So
if someone has a good guidline in how get a device (USB Functional
Client)
look like a flash disk when connected to the PC (host side) , it
is
appreciated.

My starting point was to copy the
WINCE500\PUBLIC\COMMON\OAK\DRIVERS\BLOCK\MSFLASHFMD to my work
catalog and
and do some modifications. Next I have attached my resulting log
file
generated during boot and the reginit.ini file (only parts that
has to do
with this problem).
1) Does this look OK or is there something I have left out?

As I understands your reply:
2) It is the identity "DSK2:" that connects USB driver with the
flash driver?

Looking forward for reply!
