usb mass storage class

Hi, all,

Can you give me a hand in the usb mass storage class driver? I have a
Philips ISP1160 USB host on an Intel PXA25x custom board. I used the drive
from Philips and it works well with USB keyboard, USB mouse and USB hubs.
But I have problems with the Lexar 256MB Jumpdrive. I can see that the
USBMSC.dll and USBDISK6.dll loaded. But I can't see any new folder at the
Windows Explorer. Why is that?

I searched the previous post and found that I don't have
"FSD"="UDFS.DLL" in the registry
[HKLM\Drivers\USB\ClientDrivers\Mass_Storage_Class\2]
and "FSD"="FATFS.DLL" in the
[HKLM\Drivers\USB\ClientDrivers\Mass_Storage_Class\6]
in the registry. Is this the reason? Why aren't they in my registry while
others people have them?

Many thanks.
Derek

That registry entry should be coming from common.reg, if you've got the USB
Mass Storage class properly included in your OS build. Have you added the
Mass Storage Class driver?

I do have the USB Storage Class Driver. Both USBMSC.dll and USBDISK6.dll
are included in the image and loaded when the Lexar 256MB Jumpdrive plugged
in.
(Mass storage class is the same as USB Storage Class, right?) However, I
can't see
the "USB disk" folder at the Windows Explorer.

Here is my registry:
[HKLM\Drivers\USB\LoadClients\Default\Default\8\Mass_Storage_Class]
"DLL"="USBMSC.DLL"
"Prefix"="DSK"
[HKLM\Drivers\USB\ClientDrivers\Mass_Storage_Class\2]
"DLL"="USBDISK6.DLL"
"Prefix"="DSK"
"Folder"="USB Disk"
"IOCTL"=dword:4
[HKLM\Drivers\USB\ClientDrivers\Mass_Storage_Class\6]
"DLL"="USBDISK6.DLL"
"Prefix"="DSK"
"Folder"="USB Disk"
"IOCTL"=dword:4
Compared to the registry setting posted previously, I don't have the "FSD"
keys in '2'
and '6' of my registry. I checked the common.reg and it's the same. I am
wondering
why I don't have these 2 keys.

Do you have FATFS in your image?
I would also suggest you try a number of different brands of flash drives -
they don't all behave the same way during initialization!

Have you included both the Storage Manager, and the FAT file system?

Thank you. I will try another brand. What is your experience with
different brands?

Some of the cheaper generic units actually worked better than the better
known brands! The problems we saw included devices taking 60+ seconds to
appear as a storage folder, or not initialize at all.

Thanks for your information, Martin. Can you give me the name of some
models that works? Or does anyone know a list of the validated USB
storage drive? I checked the WinCE Hardware Compatibility List and
could not find any USB storage drive on the list. How come there are
only USB hubs on the list but not USB storage drives?

A 32MB Linysys device I have works fine, as done a "Pendrive", and a couple
of house-brand devices from a local electronics store. You may also want to
check with Philips support to see what they have tested the driver with.
