[maemo-developers] Unable to get device detected with usb host mode on N800

[From: Vasudevan Srinivasan]

Hi,

I tried the usb host mode on n800 and was not success full in getting
devices hooked up.
These are the following that I have tried.

1. Compiled the kernel on SDK_ARMEL as per instructions at
http://www.muru.com/linux/n800-usb-host/ with the following patches.
kernel-source-rx-34_2.6.18-osso40.diff.gz
patches-tusb-n800-2007-05-04.tar.gz

 - make n800_defconfig
- make zImage
- flasher -f -k -R /path/zImage

2. Switching to host mode - echo host > /sys/devices/platform/musb_hdrc/mode
throws on dmesg
musb_platform_set_mode 461: Already in host mode otg_stat: 00000171
3. Used a mini-B  - TypeA cable to a powered usb hub with n800 connected to
the host port.

I could only get usb hub detected. other devices (usb flash disk, keyboard)
connected the hub are not detected.
restarting /etc/init.d/ke-recv did not help either.

Is there something I'm missing? Any suggestions to get ahead?
I also tried patches-tusb-n800-2007-04-18.tar.gz without success.
