When I boot OLinuXino with 12V power, everything works fine. But when I use the MiniUSB-OTG port, the boot gets stuck at "[ 1.684866] [sw-ehci1]: Set USB Power ON" (watching using a USB-Serial-Cable-F connected to my laptop). I use the newest official Debian image. I tried both a laptop USB port and an ATX power supply 5V line as power sources. Cubieboard runs just fine from the same USB port.

Thank you very much
Looks like a software bug so try a different kernel etc.
John
I tried with the one bought on the site, and it worked for a while and now it doesn't work anymore.
And I tried different kind of Sd card (differnt size ) with official kernel, still have the same error.
Do you know wheer it comes from
Thank you

and I still have the same problem.
No log are ritten so I'm stuck.
Can someonee help ?
Thx
It finally works.
I tried with a new kernel.
I tried with an line adaptator, the led stayed red and nothing happen.
I tried to boot with the factory android and it worked.
And for a reason I do not know I put again an homemade sdcard, and it worked !!!
I finally understood how to boot:
I have to start with the android firmware, then put the sd card, and push reset.
Hope I would help
best regards,
I saw this with another unit I built yesterday.I put the Android Micro SD in and another blank SD in and switched it on. I got the normal boot animation and then the screen went black but the backlight was on.
I let it sit like this for about 5 mins, which is way more than it should need and then powered off. I removed the SD and powered up. This time is was fine. I then inserted the SD, went to settings and formatted the SD. Now it boots OK.
I didn't have the debug cable connected this time but today I plan to try this again with another blank SD card and see what that shows.
I have the debug cable plugged.
The last line printed is

It looks like it stucks during USB power on but I do not understand why a warm reboot works in this case.
