问题描述：需要同时运行2个方法， # interface_process.run_usb_random_write()
# usb_mapping_test.main(is_flag) 测试是可以正常运行成功的。但是会报错。


class Test:
    def main(self, is_flag, case_list):
        usb_path = tools.get_usb_dispart()
        usb_mapping_test = UsbMappingTest()
        usb_rep_insertion = UsbRepInsertion()
        if "writing_dis_usb" in case_list:
            is_flag = False
# interface_process.run_usb_random_write()
            # usb_mapping_test.main(is_flag)

            thread1 = threading.Thread(target=interface_process.run_usb_random_write)
            thread2 = threading.Thread(target=usb_mapping_test.main, args=(is_flag,))
            thread1.start()
            thread2.start()
            thread1.join()
            thread2.join()

报错信息如下

你这个大概是什么应用场景？因为你调了很多自己封装的库哈。还有你的需求背景是什么，完了我本地好调试模拟一下

测试用例：需要实现，U盘读写中，然后进行U盘的映射，和弹出。这个历程的测试。
场景实现：存在A物理电脑和B虚拟云电脑。A电脑中插入U盘，远程到B电脑后，可以在远程工具栏中，点击映射，然后将A电脑中插入的U盘映射到B电脑中。
当前测试流程：

1.B电脑中启动了一个falsk服务，存在2个接口，一个是复制脚本接口，一个是执行脚本的接口。interface_process.run_usb_random_write() 这方法中调用了2个接口，一个接口是将A电脑项目中的脚本上传到B电脑，然后发送脚本执行命令到B电脑进行执行。 脚本是检测到U盘后，会针对U盘进行随机写入操作。
2.usb_mapping_test.main(is_flag) 这个接口，会进行UI操作，从A电脑点击连接到B电脑，再点击映射，断开，一些类UI操作。 这个期间，再映射成功后，被控运行的脚本，会进行随机写入操作，。也就实现了----U盘读写中，然后进行U盘的映射，和弹出。这个场景。
