Talk:AVerMedia AVerTV HD Express A918R
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=0x0918) 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
#define USB_PID_AVERMEDIA_A918R 0x0918
af9015.c
enum af9015_usb_table_entry {
AVERTV_A918R,
[AVERTV_A918R] = {
USB_DEVICE(USB_VID_AVERMEDIA, USB_PID_AVERMEDIA_A918R)},
.devices = {
{
.name = "AVerMedia AVerTV HD Express A918R",
.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

# 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 insmod /lib/modules/3.5.0-21-generic/kernel/drivers/media/rc/rc-core.ko insmod /lib/modules/3.5.0-21-generic/kernel/drivers/media/dvb/dvb-core/dvb-core.ko insmod /lib/modules/3.5.0-21-generic/kernel/drivers/media/dvb/dvb-usb/dvb-usb.ko insmod /lib/modules/3.5.0-21-generic/kernel/drivers/media/dvb/dvb-usb/dvb-usb-af9015.ko

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