Hi,
We're trying to get basic USB host mode up and running on a OMAP3530
EVM, with no success. We're (now, after many permutations of kernels
and .config settings) using the vanilla 2.6.29-omap1 kernel plus the
AUTOIDLE fix from Niilo Minkkinen), with slight additions to
board-omap3evm to allow the MMC slot to work since it hosts the rootfs
(missing regulator setup, as per dfoley's mail on 3/25).
All we've done with configuration past omap3_evm_defconfig, is to
compile in the MMC driver (to allow boot from it), enabling the EHCI
host driver (doesn't work with it off, either), and setting the
integrated USB driver to Host mode. Listed below is the resulting
.config file. We've tried many other configurations, but nothing has
worked any better.
I'd very much appreciate it if anyone knows what magic sauce might be
missing here - the USB bus debug messages indicate that the bus is being
discovered, and powered up, but no voltage appears on the USB VBus line,
and no devices are detected when they're plugged in. Sometimes we've
seen auto-suspend messages indicating that the bus is auto-suspending,
and other times we've seen nothing - but no matter what, it doesn't seem
to work.
Below is the output of "dmesg | grep 'usb\|hub' " for the above
configuration with a USB keyboard plugged in, followed by the .config file:
Thanks,
