Kernel is v2.6.36-rc2 with few minor patches adding new devices to 
mach-real6410. Board is Real6410. It seems there isn't any USB 
enable/disable bit s3c6410 registers, also no gpio multiplexing. There 
is no power control for usb on this board, it's always powered on.
Could it be driver problem? Did anybody get USB working on smdk6410 or 
other s3c64xx boards with latest kernel?

Darius.
