48 is close to 13/4 * 14,745 (If PLL will work that way). Using only 
12MHz quartz is useless.

LPC2148 datasheet, page 31 note 9. Replace W with omega (common 
mistake in documents). I think 18 Ohm value is correct value for 
external resistor (at least all other standallone USB devices from 
Philips have resistors with values around 20 Ohm). 

Philips apps ... knock knock ... :)
