OK, must be something more subtle then.

What does
  cat /sys/class/power_supply/twl4030_usb/uevent

show when it isn't charging but should be?

What does
 cat /sys/devices/platform/omap_i2c.1/i2c-1/1-004b/twl4030_bci/max_current
give?

If you
  echo N > /sys/module/twl4030_charger/parameters/allow_usb
  echo 490000 > /sys/module/twl4030_charger/parameters/default_usb_current

then plug in the power (unplugging first if necessary) does it change the 
contents of 
   cat /sys/class/power_supply/twl4030_usb/uevent
or
   cat /sys/class/power_supply/bq27000-battery/uevent 

?
