The kernel is built using the same config used on the field, where the wrong behaviour has been noted. The modified usbd and thebcscan process are embedded. After booting with the reader plugged in (normal condition): bootes 12 0:00 0:00 336K Pread bcscan bootes 13 0:00 0:00 336K Rendez bcscan bootes 14 0:00 0:00 336K Rendez bcscan bootes 19 0:00 0:00 336K Pread bcscan Here mount /srv/bcscan /n/bc gives a readable /n/bc/bcU0/data.

There are three spurious processes. On the plant (same test) there is only one.
