Developing a Linux driver using a USB sniffer

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

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,

Hi Luca,

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

Thanks to all for the replies ,

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.
