hello,
i got problems with the usb ports on my beagleboard xm, rev b. they
seem to just don't work. i'll try to describe my steps in the order i
did them so you can track:
1. first i take out the delivered sd card, put it in my computer
2. i install ubuntu 10.4.2 exactly like explained here
http://elinux.org/BeagleBoardUbuntu#Lucid_10.04.2
3. i put the sd card in my beagle and plug in: hdmi to dvi cable to a
screen, 1600mA 5v dc power to beagle, and a keyboard in one of the
four available usb ports
4. i apply power an beagle boots up
5. an install screen is shown to me on my monitor and i try to
continue, but what doesn't work is my keyboard, because it seems none
of the usb ports is powered. the ethernet seems no to be powered
either, because when i plug in the cable no lights on the ports a
flashing
i also tried folling versions for beagle of ubuntu: 10.10, 10.04.2,
10.04.1, 11.04
dmesg isn't altering anything when im plugging in/out usb devices.
what works is accessing the beagle over the serial connection, but i
want to use it as server so i need at least the ethernet port working
(and i'd like to have the usb ports too if possible).
this is what lsusb shows (only these two lines):
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
i also tried with powered usb hub, but nothing works and i don't know
what is wrong.
i'll get a multimeter today, so i could measure voltage or something
to locate the error, but i don't know what to meassure.
i hope these informations help because i would really appreciate if
someone could help me. i just don't know what to do.
thank you
