[gentoo-user] usb gadget support

[Iain Buchanan]

Hi all,

I am looking at digital dvd/hard drive recorders for dvb, and I noticed
that a lot of them are coming out with usb nowadays.  However, all I can
find out about the usb port is that it is for usb _devices_ like usb
storage, not for an uplink to your PC.

I came across USB gadget support a while ago [1], but from their web
page it sounds like you need special hardware, not just any usb port:

	"Many Linux systems will not be able to use it, since they only have
PC-style USB Host (master) hardware in a PC..."

can I plug my laptop in so these devices see it as just a large hard
drive?  I would rather not go through two steps - eg. dvd recorder to
dvd to computer; or dvd recorder to usb hd, to computer.

Or alternatively, are there any recorders with a usb "uplink"?

thanks heaps!

and then I found this [2] on wikipedia:

	"An extension to USB called USB On-The-Go allows a single port to act
as either a host or a device - chosen by which end of the cable plugs
into the socket on the unit. Even after the cable is hooked up and the
units are talking, the two units may "swap" ends under program control.
This facility targets units such as PDAs where the USB link might
connect to a PC's host port as a device in one instance, yet connect as
a host itself to a keyboard and mouse device in another instance. USB
On-The-Go has therefore defined two small form factor connectors, the
Mini-A and Mini-B, and a universal socket (Mini-AB)"

so it is possible in the usb standard - but is there a dvd/hd recorder
that has such capability and can talk direct to my PC (running gentoo of
course, to keep this discussion on-topic to the mailing list ;)

Good-bye.  I am leaving because I am bored.
