Re: LPC2148 USB

Hi, Joel

I changed P0.31 to be configured as CONNECT:
  PINSEL1 |= 0x80004000; // 0x40004000;                   /* Select
USB Link, VBUS */

The CON bit (page 225) is already set by the call in the Keil example:
  USB_Connect(TRUE);                        /* USB Connect */

But it still does not work.

By the way, my previous project with LPC2138 and FTDIChip FT2232C
started to work without any problem.  It is pity, that the LPC2148 USB
usage requires such effort.
