Nope, ports are numbered 0 and 1

Not needed, the SMDK2410 has no usb port-power control or
over-current protection.

The second usb port pins are software switchable between the
HOST and DEVICE controller. Does the bootloader leave the second
port disabled? Also, IIRC, the SMDK2410 has a hardware link
setting to change this as well.
The driver currently assumes that the machine code has set the
correct bit-settings in S3C2410_MISCCR, which the current
mach-smdk2410.c does not touch.
you may want to do the following:
s3c2410_modify_misccr(S3C2410_MISCCR_USBHOST, S3C2410_MISCCR_USBHOST);
