2009-12-18powerpc/gamecube/wii: Fix off-by-one error in ugecon/usbgecko_udbgAlbert Herranz
The retry logic in ug_putc() is broken. If the TX fifo is not ready and the counter runs out it will have a value of -1 and no transfer should be attempted. Also, a counter with a value of 0 means that the TX fifo got ready in the last try and the transfer should be attempted.
