Hi Maybe some of you have already heard some questions about the linux support of the DVB-T card "Lite On TVT-1060", but all discussions about this card said that it is not supported on linux for now, because nobody knows the frontend (chip). some also said, that you'd have to unsolder the shielding to get the name of the frontend chip.... and I won't try that as you may understand ;-) I've got this "unsupported" tvt-1060 in my Asus G2S and would like to get it run..... Operating system: Kubuntu 9.04 Jaunty Jackalope Kernel 2.6.28-13-generic With the help of g00gle i have found some infos about this tv-card: On one site, "Homocidical Teddy" wrote "The card itself is sold as a Liteon TL-1060, however it's actually a reference-design USB Tuner using the DibCom 7700C1 dvb-t chip and an UNKNOWN frontend." Found on http://forums.whirlpool.net.au/forum-replies-archive.cfm/995988.html After reading that (especially the last posts) I did some tests and edits (logically in the v4l-dvb source folder): With the command "lsusb" i got the Vendor and the Product ID: "04ca:f016" "0x04ca" for "Lite On Technology" (to find in "~/Progs/v4l-dvb/linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h") "0xf016" should stand for "TVT-1060" or another name of this dvb-t card... but with "lsusb -v" the "idProduct" is empty. This is because there is no entry for "f016" in "~/Progs/v4l- dvb/linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h". Well, as the patch mentioned (on the site above) and with a bit imagination and something like that I added #define USB_PID_LITEON_TVT_1060 0xf016 to the Product ID section in the file "dvb-usb-ids.h" (mentioned before) after that i added also { USB_DEVICE(USB_VID_LITEON, USB_PID_LITEON_TVT_1060) }, to the line 1501 (right above the "{ 0 }" entry) in the file "~/Progs/v4l- dvb/linux/drivers/media/dvb/dvb-usb/dib0700_devices.c" As i found out before, there is the struct declaration "struct usb_device_id dib0700_usb_id_table[] = { ...........}") which is as you know a device table. After these steps I took a look at "struct dvb_usb_device_properties dib0700_devices[] = {...........}" (in "dib0700_devices.c") and there was my problem! In this struct you can find entrys for the frontend and tuner attach describing an adapter and also a devices list for each of these different adapters...... NOW MY PROBLEM: In which of these sections (starting with "{ DIB0700_DEFAULT_DEVICE_PROPERTIES,") should I add a device entry for my Lite- On TVT-1060 ? Or should I write a complete new one? I have already tried this entry { "Lite-On TVT-1060", { &dib0700_usb_id_table[54], NULL }, { NULL }, }, in the device section for the adapter "stk7700d_...._attach" (frontend and tuner). Oh, and by the way don't forget to modify "num_device_descs =", it may prevent from errors I think....don't know exactly why... =) The device entry above made my dvb-t card appear in dmesg after the command "sudo modprobe dvb-usb-dib0700". dmesg output: [ 2336.075406] dib0700: loaded with support for 9 different device-types [ 2336.075499] dvb-usb: found a 'Lite-On TVT-1060' in cold state, will try to load a firmware [ 2336.075502] usb 1-4: firmware: requesting dvb-usb-dib0700-1.20.fw [ 2336.189540] dvb-usb: downloading firmware from file 'dvb-usb- dib0700-1.20.fw' [ 2336.392856] dib0700: firmware started successfully.

Now I reached my borders of knowledge =) Thanks for any replies!
