Hi Imtiaz,
I have been reading through your post on this group regarding
the SD as USB mass storage device on wince 5.0
I am also facing following issues as you.
I am able to open the drive, create a small text file, read/write a
text file of small size.
But I am unable to copy files more than 20 KB?.
Error : Path Too long
Did you do any thing specific to fix these issues.
I have one more doubt:
What happens when you remove the SD card from SD sloat when the USB
cable is still
connected to HOST. In my case I am not able to see any change on host,
meaning host is not able to recognize the SD removal, have you noticed
this.
Any pointers in this regards will be of great help.
Thanks
BMK

Hi,
My USB Mass Storage Device driver is working. Thanks for your support.
I have one query, Is it possible for me to access Storage Card through
command prompt (CMD.exe), once I dismount the USB Device ( Mass Storage
Device from my host).
I have Serial Port for downloading, and I am launching CMD.exe at
boot-up. I am able to see "Storage Card" on the command prompt before
connecting the USB Cable. Once I connect and disconnect. I am not able
to see the "Storage Card".
Thanks

I've run MSD on SDCard (on a PXA27x) without any problem on several
platforms. To narrow things down a bit you can try to run some CETK
tests on the USB function driver and the SDCard and see if one of them
fails.

Hi,
What store are you trying to expose as MSD? Filesystem?, FAT?, ISPM?,
Internal flash?, sdcard?
--> SD Card.
I am now able to open the drive, create a small text file, read/write a
text file of small size.
But I am unable to copy files more than 10 KB?.

First of all, as Valter allready explained, "DSK1:" is the store on the
device that shall be exposed as MSD to the host. What the host computer
mounts the MSD as has nothing to do with "DSK1:".
The good thing is that since the host manages to mount the MSD as a
drive letter it means that the function controller driver seem to be
working better now, because the enumeration has completed successfully.

Hi,
I was able to see the target as a USB device on the host PC.
It was mounted as a "Mass Storage Device" on my host PC. i.e [ Drive
I:\ ]
But, whenever I try to open the drive I:\, it gives me the following
errors
(1) The Semaphore timeout period has expired
(2) The request cannot be performed due to an I/O Device error.
I have the doubt since the device should be mounted as DSK1: but it has
mounted as I:?
Tools,
(1) WINCE 5.0
(2) ISP1582 Function Controller.
Thanks
