Hi there,
I'm trying to add a second USB-Bus to the system because of the
high amount of data.The OTG port would provide another Bus but has
unfortunately not enough power to operate for example a webcam.
Therefore I want to use the OTG port as host and provide the Power from the
J6 extension (Ground 5VDC and Ground). With $lsusb the device
gets recognized but will not work which is probably cause to an internal
powercheck.
I found a post in a Gumstick forum to bypass this check:
"After plugging in the device, run the following command:
echo -n 1 > /sys/devices/platform/musb_hdrc/usb1/1-1/bConfigurationValue
This disables the power limit enforcing. You may still get a warning
in the system log, but the device should work.
This has to be repeated every time the Overo is rebooted or the device
is plugged in"
but the suggested path doesn't exist on my pandaboard. Would be great if
someone could give me a hint where to turn of the powercheck.
Used Kernel is from the ubuntu-omap4-extras (3.0.0-1205-omap4)
Any help would be appreciated
