I am a newbie too and try to understand why my Pinnacle DVB-S/USB PCTV 450e does not work (not supported yet, ok) and what I can do about it (it seems that the 400e (2304:020f (?)) is not that different (same chips/same Ms-Windows driver) and is recently supported (dvb-usb-ttusb2; ttusb2.c)). I will post something later about this... But about 'learning something new', here is where I am : 1/ 'lsusb' gives the 'USB ID' of the device in the form <idVendor>:<idProduct> translated using a file 'usb.ids' (from http://www.linux-usb.org/usb.ids ; man says it is /var/lib/usbutils/usb.ids but on Ubuntu Dapper Drake, it is /var/lib/misc/usb.ids). This translation is independent of the fact that a device is supported or not... 2/ When a device is plugged into a system, something has to be done based on its Id... I though there was an 'hotplug' process somewhere, but is now 'udevd' (Ubuntu DD) (man udev ; there are configuration files in /etc/udev). I suppose it loads (modprobe) a driver based on information it finds in something like /lib/modules/2.6.15-27-386/modules.usbmap In the article http://www.linuxjournal.com/article/5604 , the author says that the file is generated when one compiles/installs 'modules'. (I upgraded my DVB modules using part of the procedure described in http://www.ubuntuforums.org/showthread.php?p=1067326) ---- So, when 'dmesg' says a new device has been plugged but doesn't catch on, it is probably a good idea to look at the file /lib/modules/<your-kernel-version>/modules.usbmap and try to find the USB-ID returned by 'lsusb' (an <idProduct> with <idVendor> on the same line). If there is none to find, try to upgrade. If not... probably write/modify a driver or wait (?) To try to modify by hand 'modules.usbmap' is probably not enough as, I suppose, a good driver will probably assess the device it is speeking with before managing it... ---- This is what I understand so far (thanks to http://www.linuxtv.org/wiki/index.php/AF9015 announced a couple of mails ago on this list) xof =================================== Jan Johansson a écrit : > > >> Note: the wiki doesn't seem to say that your stick is supported, It >> > says 'will soon be supported' or am I wrong? > > Hm, it says " > All devices below are fully supported by the LinuxTV driver.
