USB Monitor

I have a little 7" DS-70U DoubleSight USB monitor. I was able to get it working under Ubuntu by looking at posts that changed an X configuration file. I think this little guy would be great for the R-Pi. I'm not a programmer, but I bet someone could come up with code. Unfortunately DoubleSight has not entertained the idea of Linux drivers yet. And I've seen negative blogs about this. However, on their site they are looking for Linux programmers!

How much current does it draw ?

• Don't like the board ? Missing features ? Change to the prosilver theme ! You can find it in your settings.
• Don't like to search the forum BEFORE posting 'cos it's useless ? Try googling : yoursearchtermshere

According to it uses the standard DisplayLink drivers, so in principle there's no reason why it shouldn't work on the RPi.
Dunno if anybody else has managed to get DisplayLink working on RPi yet though search.php?keywords=displaylink
It may involve compiling your own kernel to get the right drivers included

Interface:USB for Signal and Power
Interface type:USB 2.0 Power
AC:not required
Power Consumption:3.3 ~ 4.9W

Looks like it needs an Amp at 5 volts. Which means you could get away with it on a good (powered) USB hub, but no chance it will work directly plugged into the (unmodded) Pi. So, not a portable solution, but still looks like a nice monitor.

There are 2 USB plugs that came with it, one for data and one for power. That would be a problem with a stock Pi, but with a 4 port powered hub, power should not be a problem. Plug the main USB into the Pi. You now have 4 ports from the hub, plus another one on the Pi. The display is really sharp. A 7" monitor is pretty small, but I was amazed how well it worked with Ubuntu. DoubleSight also has a 9 incher.
