Somebody in the thread at some point said:
| Hi there!
|
| Recently I got myself a usb keyboard for my freerunner, and it works quite
| nicely after putting the fr into host mode like described in the wiki.
Well,
| except for one little thing: It only works if the freerunner has not been
| suspended before. If it has, usb host mode seems to be broken.
| With the testing kernel, I was able to "fix" that by rmmoding and
modprobing the
| ohci_hcd module, but with earlier stable kernels, that module seems to be
| compiled into the kernel :(
|
| Any ideas how I can fix that without upgrading to a new kernel? Is
there some
| special file in /sys/ or /proc/ which I can use to "restart" the usb
subsystem?
|
| Or, if that isn't possible, how I can upgrade to a new kernel without
breaking
| my current distribution (which is FDOM from October 2008)?

Does it help if you reassert the two host mode things by hand in /sys?
