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.

I noticed too that, if I try to copy ONE BIG file(700mb) from the SD to an external SD, it will go really fast in the first 20mb, but will start to slow down up to the maximum of 200mb(in my experiences) when it will "break" - mostly will break before. I'm yet to test with other hub to see if it is a problem with my actual hub, but I'd like to let it registered. I hope someone tried to copy some file from the SD to an USB SD reader to confirm or deny that. I'm yet to test from the internal memory to the USB SD reader too.

And, finally, I guess this is related with the power kernel: It does not like to reboot. Almost always, when I ask it to REBOOT, it will reboot, but not actually boot, it will start to boot and then, turn off. Then I need to turn it on manually. Is anybody else experiencing this?

I'm yet to retry the maemo-pc-connectivity, to see if it is working.

Thanks.
