[manricoprevital]

I have to use a particular (not NXP) USB stack.

I have used this stack for kinesis K20 familiy.

Are the same USB HW cell in the K20 and K24 family?

Hi,

No, K24_120: USB 2.0 On-The-Go (full-speed) with USB transceiver.

K20_120: USB 2.0 On-The-Go (full and high speed).Current/time for portable USB devices enabling longer battery life. 

So they are different.
