	I just tried using one myself (I have not used one in a while, and
wanted to double-check a couple of points), and am no longer able to
mount a USb key either.  Is anyone else having trouble?  Perhaps
something has been broken along the way: I am using 2.6.14-omap1, but
have not used a USB device since around 2.6.8-omap1.

Hi,

I had problems with an USB flash memory, too. I tried several solutions
and kernels which did not work until I recently read a post on the Linux
Omap mailing list regarding USB clock malfunction on kernels
2.6.12-2.6.14 (which were the ones I have tried). Then, I tried kernel
2.6.11 an it worked.

I've noticed that having CONFIG_OMAP_RESET_CLOCKS on kills OHCI at least
on OSK. Juha's patch from few months ago probably helps with that as it
turns on dc_clk:

http://linux.omap.com/pipermail/linux-omap-open-source/2005-August/004818.html

Can you please check if it's caused by this combination? We should get
Juha's patch integrated...

[Jose Manuel Cano Garcia]

Hi Tony,

That option was indeed active in the .config file. Let me a couple of 
days to recompile the 2.6.14 kernel without that option and try it again.

Best regards,

Jose.

	I just tried removing CONFIG_OMAP_RESET_CLOCKS, and everything worked
as expected.  If I apply the above patch, then restore
CONFIG_OMAP_RESET_CLOCKS, then things still work: seems to be a Good
Thing.

OK, let's wait for comments from Dave on that patch before we push it.

Hi Tony,

The patch work. Now the OSK can detect the USB key automatically.
Thanks much.

RE: OSK5912 USB Port Problem

[Li Weichen]

Well I encounter another problem.  If I only enable the usb host support,
the usb Flash disk works well with OSK.  But after I add the USB Gadget
support, and enables the OTG, the Flash disk doesn't work.

Is there anything wrong with OTG?

Re: OSK5912 USB Port Problem

[Jose Manuel Cano Garcia]

Hi Tony,

I had some time to test the patch with the latest kernel I could get 
with git (I think its 2.6.15-rc2 now). With that patch USB works OK. I 
think someone has tested it about a day before, but this it to confirm 
that it really works.

This is great for me because 2.6.11 had not driver support for the 
OSK5912 sound device.

Thanks,

Jose Manuel

Hi,
	I did not follow all the thread but if I'm correct, when you enable the Gadget support in the Kernel for the OSK, the USB can no longer be used as a Master.
