It only depends on libusb-1.0 and should compile and run on any Linux system.

The Mettler Toledo PS shipping scale family (PS15, PS30, PS60 PS6L and PS90) use the range of product IDs from 0xF000 to 0XF007. If the product ID is in that range then you are talking to a Mettler-Toledo PS shipping scale that supports HID-POS.

i try this code

HidDeviceData inData;
HidDevice[] hidDeviceList;
HidDevice scale;

bool? isStable = null;
decimal? ounces = null;

hidDeviceList = HidDevices.Enumerate(0×1446, 0x6A76);

if (hidDeviceList.Length > 0)
{
int waitTries;

scale = hidDeviceList[0];
waitTries = 0;

scale.Open();
Thread.Sleep(500);
// For some reason, the scale isn’t always immediately available
// after calling Open(). Let’s wait for a few milliseconds before
// giving up.
while (!scale.IsConnected && waitTries < 10)
{
Thread.Sleep(500);
waitTries++;
}

if (scale.IsConnected)
{
byte[] zero = new byte[] { 3, 2, 11, 255, 0, 0 };
scale.Write(zero);

Thread.Sleep(500);
}

scale.Close();
scale.Dispose();
}

but not working.

any help will be very appreciate,

thanks

A solution …

To interfacing any USB scale like …
Mettler Toledo, Pitney Bowes, Fairbanks, X.J., CHARDER, Pelouze, SANFORD, DYMO, Endicia, ELANE XM, UNITED STATES POSTAL SCALES PS30USB/PS311 30-LB DIGITAL USB POSTAL SCALE

You can use the software BillRedirect like a driver ! This software can send the weight directly in any application .NET or can also support:
- Output weight to a Virtual Serial Port that you can use in your .NET source code.
- Output weight to an ASCII file that you can use in your .NET source code.
- Output weight to a TCP connection (client or server) that you can use in your .NET source code.
- Output weight to a UDP Broadcast packet that you can use in your .NET source code.
- Turn your USB scale to a wedge keyboard emulation.
…

It’s very difficult to get the API from manufacturing scale company ! Often they must buy SDK kit which was very expensive with a license agreement Grrrr. Right now I think that BillProduction is the only company that offer a compatibility with USB scales like a driver.
