Hello

I am also having problems with my LPC2468 working with some flash drives, even of the same manufacturer, same size.

The code we are currently using is a version of  usbhost_lpc2468.c

What we would like is the latest version of

USBHostLite for LPC23xx/LPC24xx V1.00 (Jan 4, 2010)

from the site:

http://www.lpcware.com/content/project/nxp-peripherals/usb-nxp-microcontrollers

because the link is broken. It goes no where.

Or do you have a driver for the USB for LPC2468 processor?


Our failure is inside the

if (!(TDHead->Control & 0xF0000000)) {
        return (OK);
    } else {
        return (ERR_TD_FAIL);
    }


Sometimes the USB flash devices pass this, return and Ok, other USB's return an ERR
where we read a 0x5.... instead of a 0xF.....

Any help anyone can give would be much appreciated.
