sorry for me not being responsive WRT your first mail.

i made the first mail about this usb adapter, but, then, i just had the 
time to check that i could get the "dump" of the USB transaction using 
those usb sniffer.. the same info it seems your are using to proceed 
with the protocol analysis! cheer to you!

actually i'd like to help this effort with some test but our usb adapter 
is used as a field test device for DVB-T signal availability here in 
nothern-east of italy, so it's not always in my pocket to maybe test & 
verify your protocol-related question..

hope to see this kind of driver on a cvs.

BTW i'm wondering if this kind of usb driver could be completely an user 
space application because it's based on best-effort usb transaction 
(dont remember the exact term in usb terminology; not synchronous, i 
mean) and i remember there are already user space application acting 
like driver for other usb adapter.
this way, an alpha-state driver should be less of a pain WRT crashing 
the running kernel!

bye
