Does the baud rate of ftdi for android support 921600?

I changed the baud rate to 921600, and the content I often read is empty.
It is normal to use 921600 to read the ftdi device on Linux.

Tested with this：https://github.com/HelloZB/QtAndroidFTDI

It is supported, just modify the size of the buffer area
//QtFtdev.java

  String readData()
    {
        int readcount = ftDev.getQueueStatus();
        byte[] usbdata = new byte[readcount];

        if (ftDev.isOpen() == false){
            lastReadLen = -1;
            return new StringBuilder(0).toString();
        }


        if (readcount > 0){
//            if(readcount > USB_DATA_BUFFER){
//                readcount = USB_DATA_BUFFER;
//            }
            ftDev.read(usbdata, readcount);
        }
        lastReadLen = readcount;

        return byteArrayToHex(usbdata);
    }
