After some days of investigations without any success, conclusion is:

!! Help needed to make "AVerMedia AVerTV HD Express A918R" working in linux. !!

= Investigations =
== Step 1 ==
What I tried is to tweak ''''dvb-usb-ids.h'''' file so that the A918R card (Id=0x'''0918''') is seen as default AFATECH_AF9015_9015 (Id=0x9015):
/* #define USB_PID_AFATECH_AF9015_9015 0x9015 */
#define USB_PID_AFATECH_AF9015_9015 0x0918
If this works, the conlusion would be that there is no special tweaks necessary for card A918R, which could be then added to files '''dvb-usb-ids.h''' and '''af9015.c''' files for next updates.

I also tried to add this line to '''/etc/modprobe.conf''':
alias usb:v07CAp0918d*dc*dsc*dp*ic*isc*ip* dvb-usb-af9015
but no luck.

== Step 2 ==
Tried compilation from hg_clone or media_build, but got this error I could not solved:

# make
make -C /home/share/DVB/hg_clone/media_build/v4l
make[1]: entrant dans le répertoire « /home/share/DVB/hg_clone/media_build/v4l »
perl scripts/make_config_compat.pl /lib/modules/3.5.0-21-generic/build ./.myconfig ./config-compat.h
'''Usb headers not found''' at scripts/make_config_compat.pl line 239.
make[1]: *** [config-compat.h] Erreur 2

Then tried to from linux source 3.5.0, using kernel 3.5.0-21-generic, after modification of following kernel media files:


'''dvb-usb-ids.h'''
'''dvb-usb-ids.h'''
#define USB_PID_AVERMEDIA_A918R 0x0918
#define USB_PID_AVERMEDIA_A918R 0x0918


'''af9015.c'''
'''af9035.c'''


enum af9015_usb_table_entry {
enum af9035_id_entry {
AF9035_07CA_0918,
AVERTV_A918R,


[AVERTV_A918R] = {
[AF9035_07CA_0918] = {
USB_DEVICE(USB_VID_AVERMEDIA, USB_PID_AVERMEDIA_A918R)},
USB_DEVICE(USB_VID_AVERMEDIA, USB_PID_AVERMEDIA_A918R)},


.devices = {
.devices = {
⚫
.name = "AVerMedia AverTV A918R",
{
⚫
.cold_ids = {
⚫
.name = "AVerMedia AVerTV HD Express A918R",
&af9035_id[AF9035_07CA_0918],
⚫
.cold_ids = {
⚫
},
&af9015_usb_table[AVERTV_A918R],
⚫
},

'''Result''':

# modprobe dvb-usb-af9015 -v
insmod /lib/modules/3.5.0-21-generic/kernel/drivers/media/dvb/dvb-usb/dvb-usb.ko
ERROR: could not insert 'dvb_usb_af9015': '''Exec format error'''

# file dvb-usb-af9015.ko

# dmesg
kernel [ 6346.104417] dvb_usb: disagrees about version of symbol module_layout

=> no idea how to solve "ERROR: could not insert 'dvb_usb_af9015': Exec format error"

== Step 3 ==
Compilation success with kernel 3.5.0-21 and files modification step 2

# '''modprobe -v''' dvb_usb_af9015

------------------------------------
= Current status =
AverTV A918R needs some deeper investigations.
If someone knows how to make some further test, please advise.

Thanks.
