USB 2.0 Host controller crashes in Android.

I've been using this board for awhile now and just ran across an issue with USB. After some time (sometime hours, sometimes minutes) the devices disappear and I see the following message in the kernel messages:

Code: Select all

[ 3893.229656] ohci-platform fe3a0000.usb: frame counter not updating; disabled
[ 3893.229760] ohci-platform fe3a0000.usb: HC died; cleaning up

[ 6585.523002] usb 2-1: USB disconnect, device number 2

It looks like the host controller is hanging and the kernel is disabling it. Since our product relies on USB we really need this to work. Any ideas on what I can do fix this?

Thanks,

So nobody at FriendlyElec reads these? Was hoping for an update...

Thanks,

For anyone else having this issue, I found a patch that seems to fix it.

I had to tweak it a little to patch against the kernel version in the android source, but after weeks of leaving the system on I no longer loose USB ports.
