那个设定
我需要编写能够使用连接到 USB 端口的多种类型的条形码扫描仪的程序。
所有这些扫描仪都具有“串行端口模拟”类型的模式，其中（根据我的理解）它们的行为应该像简单的字节流设备一样。
但其中一台扫描仪的行为有所不同。它仅发送固定长度（64 字节）的块，其中第一个字节是数据的长度，然后是数据字节并用零填充，直到块的末尾。
每个块只能在设备上的单次读取操作中读取。即使读取一个字节，也会导致整个块从 IO 流中消失。
扫描仪被检测为 HMI 设备（使用 lsusb）：

为了进行比较，下面是另一个扫描仪的 lsusb 输出，它的行为与普通字节流设备相同：

插入条形码扫描仪时的 dmesg 输出：

问题：
如何配置 Linux 来将此扫描仪作为字节流设备来处理？
