A web search led me to discover that the firmware provided with ubuntu is out of date, despite the fact that the most recent was released in 2010 :
$ md5sum /lib/firmware/dvb-usb-af9015.fw dccbc92c9168cc629a88b34ee67ede7b /lib/firmware/dvb-usb-af9015.fw

Just replaced it and crossing fingers. I'll wait to check if it solves the issue before trying the (non downgradable) bios update.
