[Tinyos-help] Problem with USB-to-Serial Cable for mote-pc communication

[John Regehr]

I used to teach a course based on project boards with serial ports, so of 
course students using serial-free laptops had to buy USB-serial 
converters.  Broadly speaking, these devices (and/or their drivers) are 
total pieces of crap.  Seriously, about 1 in 3 worked as advertised.  My 
advice is to keep buying more of them until you find one that works for 
you, then buy a small pile of that model.
