Re: How do I load a third party driver in Windows CE 6.0

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi Bruce,
I read the documentation here.

http://msdn2.microsoft.com/en-us/library/aa918154.aspx

I though if I matched the parameters of the device that I am trying to plug
into the usb in the
HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients and gave the name of my dll
I would get a dll to load. I guess this isn't right? So let me turn the
question around. What do I have to do in the registry to get my dll to load?

No.

What documenation are you refering to?

That key is the root of where you need to put your keys, but I can't cross
reference what you have done enough to try to straighten you out.

Hi Bruce,

What I am getting from the documentation is if I add the following
registry
entry

[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients]
"VendorID"=dword:1905
"ProductID"=dword:1956
"DeviceClass"=dword:0
"DeviceSubClass"=dword:0
"DeviceProtocol"=dword:0
"Dll"="myusbdevicedriver.dll"

then myusbdevicedriver.dll will get loaded when I attach my USB device.
Is
this true?

You need a USB Host Class driver since you will be plugging it into the

Hi,

I have been reading some of the documentation for USB drivers. It is
unclear to me which type of drivers I need to read and write the end
points
described below for my USB to 485 converter. I think I need a USB
Function
Serial Client Driver can anyone confirm?


Device Descriptor:
bcdUSB: 0x0110
bDeviceClass: 0x00
bDeviceSubClass: 0x00
bDeviceProtocol: 0x00
bMaxPacketSize0: 0x08 (8)
idVendor: 0x1905
idProduct: 0x1956
bcdDevice: 0x0400
iManufacturer: 0x01
iProduct: 0x02
iSerialNumber: 0x03
bNumConfigurations: 0x01

ConnectionStatus: DeviceConnected
Current Config Value: 0x01
Device Bus Speed: Full
Device Address: 0x01
Open Pipes: 2

Endpoint Descriptor:
bEndpointAddress: 0x81
Transfer Type: Bulk
wMaxPacketSize: 0x0040 (64)
bInterval: 0x00

Endpoint Descriptor:
bEndpointAddress: 0x02
Transfer Type: Bulk
wMaxPacketSize: 0x0040 (64)
bInterval: 0x00

Serial communications USB-drivers typically goes into:

[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\<X>_<Y>\Default\Default\USBSER_CLASS]

where <X> is the USB vendor id in decimal(!) and <Y> is the device id
in
decimal.

But you should probably check what values you need with FTDI. At least
you'll need the Dll-value:

"Dll"="mydrv.dll"

Btw have you tested communication with the driver, last I checked FTDI
wasn't to eager to provide CE6 implementations of their drivers.

Hope it helps,

Hi,

I have a USB to 485 converter with a FTDI chip on it. FTDI supplies
an
inf
file and a dll that supports windows CE. Currently I have to copy
the
inf
and dll file to the windows directory and when I plug the USBto485
converter
in a window pops up and I have to type the name of the dll in that
window and
it works. I would like this to be more automatic. I am assuming
that
I can
modify a bib file in my project and get the files in the windows
directory,
but how do I make it so the window does not come up asking me for
the
name of
the dll? Are there registry entries I can add so the dll is already
present?
