OK, so I dissassembled the miniUSB cable and after some measurments can confirm it is mini-A type cable.
It is suggested to load g_file_storage, but it is compiled directly into the kernel.
I just tried with a USB keyboard. Logitech Corded. Nobody. Nothing in dmesg, no LEDs on the keyboard. AC pluged into the tablet, also unpluged. Just nobody.

I revised the kernel settings. It's all OK. As far as I can see everything that should be included IS included.
So I tweaked logging level for the USB subsystem (increased it in kernel .config) and I am recompiling at the moment.

So I think I have correctly configured and compiled kernel, but nobody responds on the USB. Should I inject power for devices like simple USB stick and keyboard?

Does anybody has any clues? I will also post on maemo-developers.



EDIT: Damn it! I recompiled with increased verbose level. Again nothing. Nobody. Silence.

According to this topic there should be at least something. Could it be that the tablet can't power even a simple flash key?
I will now try to cook cable with option to inject power.

EDIT2: That's it. I did everythong I could think of. I measured the power lines on the USB, coming from the tablet. 0.00V. So I found an old USB-B to USB-A (The big ones) cable. Cut the B end (the square one), pluged the A end into the PC and got 5.02V btween black and red. Then I took the cable coming from the tablet, cut blag and red and connected the ones coming from the PC to the ones going to the peripheral.

So after all here is what I got:
- Nokia N800 flashed with kernel with latest patches (patches-tusb-n800-2007-07-03.tar.gz)
- mini-A cabel plugged into the tablet
- Replaced power lines coming from the tablet with those coming from the PC, providing 5V@0.5A
- USB Keyboard/USB Flash connected on the end of this cascade

- NOTHING in dmesg; Neither in /sys/bus/usb/devices


I also noticed that "cat /sys/devices/platform/musb_hdrc/mode" returns b_idle.


Guys, I am desperate!
