用PC模拟USB闪存驱动器
我有一个奇怪的问题。 情况是我有一台电视,可以使用 USB 闪存驱动器作为播放电影的源。 你认为有可能直接将PC和电视USB转USB并使用一些软件接口来确定PC就像闪存驱动器一样吗? 我认为这可以通过硬件驱动程序来完成,但我想知道是否可以在没有硬件驱动程序的情况下完成。
I have a peculiar question.
The case is that I have a TV that can use as source a USB flash drive for playing movies.
Do you think it would be possible to directly connect a PC and the TV USB to USB and using some software interface to determine the PC to act like a flash drive.
I think it can be done with a hardware driver, but I'm wondering if it can be done without that.

不,你不能,即使编写一个新的驱动程序也不能。
闪存驱动器是一种 USB 设备,但您的计算机只有 USB 主机端口。设备与主机需要不同的电路(有些电路可以同时实现这两种功能,称为 USB on-the-go,但这些电路仅存在于外设中)。
No, you can't, not even by writing a new driver.
A flash drive is a USB device, but your computer has only USB host ports. There's different circuitry needed in a device vs. a host (there are circuits that can do both, called USB on-the-go, but those are only found in peripherals).
事实上,你可以——有点。

这是一款内置 Wi-Fi 适配器的特殊适配器,可让您连接到计算机(或互联网)。
不完全是你问的,但效果相似。
Actually, you can - kind of.

This is a special adapter with a Wi-Fi adapter built in that allows you to connect to a computer (or the Internet).
Not quite what you asked but the effect is similar.
