Hello, I´ve been taking a look at the existing posts, but no one of them solves my problem... I am triyng to port keil USBMem example to GNU. I´ve made all the __packed changes suggested in different forums, data allignment ones and many others, but I still don´t manage to have the board understood by the PC as a proper USB device. Has anyone managed it? Is there some code anywhere? Else... what could I try or check to solve my problems? Thank you very much for your help! Best regards, Ruben.
I have once ported the HID-example from NXP which is made for the Realview/Keil tools to GNU tools. I will search for the code... As far as I know LPCUSB (see sf.net) does also support LPC23xx/24xx. You may give it a try.

The top layer (and the one not giving problems) is the only difference between the HID and the Mass Storage class applications. Cheers, Ruben.
I think it could also be a problem of the interrupt handling, with something related to the startup file and/or the linker .ld one. Could that be a reason? Thanks!

I have been trying also this, but running in debug mode, it gets stuck in the PLL lock...
May it be a problem of the interrupt? Did you find the code? Thank you very much!
