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
Regards
Luca Ellero

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
T.

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,

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
https://www.kernel.org/doc/Documentation/usb/usbmon.txt

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.
