OK, "unknown device" sounds like a usbfn problem. You know, it's really
hard to make any intelligent suggestions without any debug info. I
think the "debug output" you pasted are actually retail messages so it
sounds a bit quiet to me. You're running a debug built image?

Hi

Just to be sure, you've tested that the SDCard is working OK?
-> Yes its working
When you put a SD memory card in the slot it appears in the file
system, right?
-> Yes ( Since GPIO interrupts are not working, we cannot do Hot
plug-play). The card has to be inserted before.
What debug output do you get when you attach the USB cable and have a
SD memory card in the slot?
-> Nothing seems to come. ( I doubt this is due to GPIO interrupts not
working on our target)
On Host PC "Unknown device"

When I was debugging the BOT_DeviceNotify() function, I checked it out
that the control is not going to Store_Init() function or UFN_ATTACH
function. It just directly goes to UFN_MSG_PREPROCESSED_SETUP_PACKET
case and thats all.

Hi Henrik,

I have changed the "DeviceName" to "DSK0:" and "DSK1:, but still same
status.

I was unable to connect to the device using Remote Registry Editor. My
download and debug are through Serial.

I have following doubts regarding USB Mass Storage Device

(1) Before USB Function Controller loads, is it required that "Storage
Card" should be mounted.

No, it is not required that the storage card is mounted when the msd
driver is loaded. However, it is required that the store the msd will
share (in this case the sd memory card) is mounted when the usb cable
is connected.

(2) Does "Storage Card" registry needs modifications to support USB
Mass Storage device.

No, it shold not need any alterations.


(3) Is "RAMDISK" needs to be added. (SYSGEN_RAMDISK).

No. ramdisk has nothing to do with msd and sdcards.

The "DeviceName" registry setting looks wierd. It should match the
device manager name, i.e. "DSK0:" or "DSK1:" etc. If you're not sure
what name the SD Memory Storage class driver gets when it is activated,
you should be able to find it under
[HKEY_LOCAL_MACHINE\Drivers\Active] using the remote registry editor.

Hi,

I want to expose my SD Card as a USB Mass Storage Device. Here are the
details of the target device

(1) ISP1582 Peripheral Controller
(2) WINCE 5.0
(3) Have the physical device driver(PDD) from philips.

I have included the "Mass Storage" Component from the catalog.

The Device is registered and it has activated the "Mass Storage Class"
Client driver.
But on my PC it shows as "UNKNOWN DEVICE" found.

How can I set my registry, so that it corresponds to my SD CARD. SD
Card is mounted as
"Storage Card" on my target.

Here are the registry settings
