Comment(by iknowjoseph):

 I've suffered this problem too. Although lsusb seems to fix it. Running
 this after a suspend operation would not enable a usb keyboard to work:

 ifconfig usb0 down
 echo "host" > /sys/devices/platform/s3c2410-ohci/usb_mode
 echo "1" > /sys/devices/platform/neo1973-pm-host.0/hostmode
 echo USB-Port is in host-mode now.

 but this would:

 ifconfig usb0 down
 echo "host" > /sys/devices/platform/s3c2410-ohci/usb_mode
 echo "1" > /sys/devices/platform/neo1973-pm-host.0/hostmode
 lsusb
 echo USB-Port is in host-mode now.
