I study informatics and engineering in Hungary, on the best technical university of Hungary. I've got two rpi, the first limited edition's model B, and a revision 2 model B with half GB of memory.
First, I tried with a low-cost keyboard, a noname mouse, an HDMI fullHD LCD, a power supplied USB hub with 10 ports, and a huge 2.5A micro USB power supply. I use a Samsung 8 GB class 6 SDHC (and sometimes a Kingston 32 GB class 10 SDHC) with Debian Wheezy.
The keyboard was not correct, because some keys was working, the others not.
I've got a very good keyboard with no extra functions, with no lights, etc. So, it is a very good keyboard, but it needs minimal power. And I've got a very good gamer mouse, but for the first times, not plugged in. The other things did not changed.
This keyboard is better, but some keys still not working. This is a USB keyboard, with no ps2 / usb converters. For example, "a" and "s" not working. It's a hungarian painted keyboard, but pi uses it as an english keyboard, it's okay, no problem, z and y are y and z. But, the button painted "z" is not y, this makes nothing. The button painted "y" makes z good.
Most of the rpi OS, the factory login + password is "pi" and "raspberry". I can't type it, because the password contains "a", "s" and "y" as well. I can't turn it on. :-'(
I asked it in a hungarian unofficial rpi forum, and here too. Please help me.
Sorry for my very bad english grammar, I should learn it
