Yes to all of that. But IANAL. You cannot MARKET a DEVICE without paying
The Man, as it were. But as far as I know, but aren't coming for the driver
writers..yet.

Just though I'd point out that WireShark http://www.wireshark.org/ already
has usb sniffing builtin http://wiki.wireshark.org/CaptureSetup/USB It uses
the usbmon which is already part of the kernel

Would you ask a doctor for legal advice?  If not, why ask a programmer?
If you have legal questions, ask a lawyer in your country, they are the
only ones that can give you a definitive answer.

good luck,

Hi Luca,
I think your question is really interesting. In my opinion, it depends
on the country where you live. If it's illegal in your country, it is
for you but not for other people. Laws may drastically vary depending
continents and countries.
Cheers

Developing a Linux driver using a USB sniffer

2014-05-05 Thread Luca Ellero 
Hi all,
can someone please tell me if it is legal to develop an USB driver 
analysing the USB protocol with a USB sniffer?
Can this driver be made public under GPL?
Thanks
