New code version of P4

We published on Tuesday not the most recent version of the P4 code, but it is now updated. The newest version of the  P4 code (and P5 and P6) solves most problems we experienced with USB 2.0 previously. However, we have still a problem with USB which we could not solve, as it is a problem with the BIOS/hardware. The same problem is in linux. The newest P4 may not boot occasionally on real hardware, but that after a couple of reboots it should work.
