I have attached a USB to serial converter to the Asus (the very same
setup works on my laptop as I mentioned) and tried to issue the command
below.
The problem's that, once the owfs seems to start ok, if I try to change
into the directory the cd command hangs. The system works from another
console, the CPU is not hogged.
