the internal USB hub runs at Full Speed (12 MBit/s), resulting in a maximum USB disk I/O of 1.5 MByte/s
since the board does not feature Ethernet itself, I tried to attach a USB Ethernet controller to it, but of course the transfer rate through that is by the I/O upper limit of the USB hub
I did not test wireless but it is not feasible for what I am trying to do anyway
Which kernel version are you using on the Origen? I noticed the same problem a while back, but it appears to have been fixed in the Samsung landing team tree.
Here's the output of 'uname -a':
Linux linaro-developer 3.2.0-1000-origen #0samsung14-Ubuntu SMP PREEMPT Wed Jan 11 18:56:28 UTC 2012 armv7l armv7l armv7l GNU/Linux
Got the kernel from
http://snapshots.linaro.org/oneiric/lt-origen-oneiric/20120313/1/
There is still another bug present in the Origen kernel preventing USB-ethernet working with EHCI. Some patches have been posted, but they have not made it into the trees yet. Search the mailing lists for s5p usb burst to find them.
Is there any estimate on when this (them being merged into the landing team trees) might happen?
