Howto make you Windows PC act as a USB-mass-storage-device?

[23054467]

I want to play media files stored on my computer on my TV, but I don't want to use the built-in TV-out card. Instead I want to use my stand alone DVD-player, which supports playing media files from a USB-stick.

So, I want to connect my PC-to the DVD-player using a USB cablee and emulate USB-mass storage on the PC to "share" a folder as a USB-drive.

How can this be done?

I don't think that it can be done. Did you consider using an USB hard drive.

I have a USB-harddrive, but I would really like to connect my PC instead.
What makes it impossible? Hardware constraints?

I have sucecssfully used USB cables for peer-to-peer communication between two PCs, so why would this be diffrent?

[DonRayner]

I believe that the only reason is that no drivers have ever been written to enable a PC's usb port to act like a mass storage device.

Well, I'm still not convinced. I picked up this from the Linux world, where everything seems possible ;-)

"The <linux/usb_gadget.h> API makes it easy for peripherals and other devices embedding GNU/Linux system software to act in the USB "device" (slave) role" from Linux-USB Gadget API Framework.

So why would it be impossible in windows?

Did you actually read the article?

Many Linux systems will not be able to use it, since they only have PC-style USB Host (master) hardware in a PC, workstation, or server. But when you're putting together embedded Linux systems, a USB peripheral controller option is routine; it's often integrated into processors.

Ehh, no, apperntly not. Ok, I'm convinced so thanks Don for your tome!
