V vetteman Member Licensed User Longtime User Mar 28, 2019 #1 Hi, I am trying to get the full serial number of a USB device. I programmed an FTDI dongle with their own software as FT93452. When I re-read the serial number with the FTDI software it reads back the complete S/N. When I run this command: Code: Dim data As String data = usb.DeviceInfo(i+1) ToastMessageShow(data, True) I get this for the serial number: "Serial : FT9" Why are only three digits available? It would also be nice if the serial number was made available??? Thanks

I've dug out up the source from six years ago and the serial number is returned as a C style zero terminated string from a location determined by the Raw Descriptors of the UsbDeviceConnection provided by the Android UsbManager for the device. So it seems that is what the Android API is returning. Upvote 0

Okay thanks, the fact that it's three char's still gets me a long way for the number of devices that can be filtered when connected. Upvote 0
