Hello folks.

First, thanks to the community, because I have been reading a lot the forum to help me !
This made understood the "real "power of n770

however, after following many tutorials, threads and etc... I am not able to use the USB host.

Here is what I did
1) downloaded the linux flasher and latest Hacker firmware (from devs-tablet.nokia...)
2) loaded the firmware
3) enabled the host mode
4) enable the RD mode

so, in that state, I guess I have fulfilled all the software prerequisites

Now the hardware

I bought :
a) a powered hub (irock 4 USB ports and 1 mini USB port)
b) a USB charger used as power injector (http://www.pearl.fr/article-PX2004.html it allows to be charged through male USB and then deliver power with the female USB)

Alright
so I connected my injector to my hub (from the female port on the injector to the mini female on my hub).
I tested, and all USB female ports delivers 5 volts. I connected my usb card reader, and I can get the blue light stating the card gets power.
so I *assume* that should be alright
Then I connect my N770 to my hub and... nothing
USB keyboard does not work, cards from my card reader are not seen in /dev/

here a dmesg when connecting my hub+car (see below since it's long...)
I can see the "bad cable" but I tried 3 differents with the same (I used 2 of them to flash with no error, though).

Last: I do not get anymore the USB icon

I have tested almost anything (regular nokia firmware, host enabled or not, etc...). If anybody has an idea, (s)he's the most welcome.

TIA

Vincent
