It was closed. In fact, I tried after rebooting just to make sure - thanks! Good news: Now I was able to get a SD reader recognized and working AND recognize (but not work with) my modem. I didn't knew that I needed to install h-e-n. I thought that it was installed alongside power kernel, now that they are together, and that was then a command prompt, but I was wrong. Bad news: I noticed that after using h-e-n (and closing it), if I go to charge my device (and then shut the screen backlight), it will glow, whenever it needs to glow, but REALLY WEAK and then, from nowhere, goes normal again. And then, randomly, will glow weak again. I just saw that happening RIGHT NOW. I don't know why, maybe some thing is reverse charged and the it needs to wait until discharge, I just see that it does that.
