Beware if you have more than one DVB adapter, though. It seem like the dvb_af903x driver can't tune if it isn't adapter 0, at least not in my system.

I picked up this device in Australia from Dick Smith Electronics (DSE) labelled "Gadget Geek". Have tested this in Maverick using Me TV.

Also, on sale in Australia inside a box which says Blaze HDTV Tuner, inside which is another package which says MinTV DVB-T Stick.


Install instructions for using alternate manufacturer driver

I've pre-hacked the manufacturer's driver:

  1. The source extracted from the manufactuter's driver
  2. The missing crystal frequencies commented out from line 178-187
  3. Commented out #include <autoconf.h> from api/usb2impl.c

First up, you'll need a working build environment, the kernel-headers and the kernel-source. If you don't know which kernel you're running, you can find out with

uname -r
sudo apt-get install build-essential linux-headers-2.6.35-25-generic linux-source-2.6.35 kernel-package
sudo tar jxvf /usr/src/linux-source-2.6.35.tar.bz2
wget http://me-tv.googlecode.com/files/AF903x.tar.gz
tar zxvf AF903x.tar.gz
cd installer
cd AF903x_SRC
ln -s /usr/src/linux-source-2.6.35/linux-source-2.6.35/drivers/media/dvb/frontends/*.h .
ln -s /usr/src/linux-source-2.6.35/linux-source-2.6.35/drivers/media/dvb/dvb-core/*.h .
ln -s /usr/src/linux-source-2.6.35/linux-source-2.6.35/drivers/media/dvb/dvb-usb/*.h .
cd ..
sudo ./installer.sh

If you run

dmesg

you should see

DRIVER_RELEASE_VERSION : v9.08.14.1
FW_RELEASE_VERSION     : v8_8_63_0
API_RELEASE_VERSION    : 200.20090402.0
usbcore: registered new interface driver hiddev

End Michael Lamothe's notes

Beware if you have more than one DVB adapter, though. It seem like the dvb_af903x driver can't tune if it isn't adapter 0, at least not in my system. In my case, I also have a Hauppauge PCI DVB-T card that always got installed as adapter 0, with the Afatech as adapter 1. With the Hauppauge card installed, the Afatech would always fail at tuning. With it removed, it worked. I got around this by blacklisting the cx88_dvb, cx88xx, cx8800 and cx8802 modules and loading them manually after the dvb_af903x had loaded. Now, with the Afatech as adapter 0 and the Hauppauge as adapter 1, both work great.

Might simply be some specific incompatibility between the Hauppauge driver and the Afatech, but I thought a heads up might be in place.

General important note! (1) USB DVB is wrongly identified as a HID device

Most Linuxes improperly identify this USB stick as USB HID, which it is not! This leads to driver conflicts. When looking into:

dmesg

There is mention of a HID device, by default, after plugging in the stick.

This has to be done, in order to remedy this:

  • 1. /etc/modprobe.d/usbhid.conf needs to have the line (for module version):
options usbhid quirks=0x15a4:0x1001:0x0004

This line ignores this ID from HID devices! If there is a real physical USB device present, which is HID, i.e. keyboard, mouse (funny, this should never have happened, according to the specification, that two or more devices share the same USB ID!), it must not be 15a4:1001, or it will be ignored!

  • 2. if HID driver is incorporated into kernel, these boot parameters must be appended:
usbhid.quirks=0x15a4:0x1001:0x0004

this goes in, i.e. /boot/grub/menu.lst (grub.conf) , or other means of linux bootconfig.

  • 3. Reboot, just in case. :) Or, unload and reload the usbhid module, in order for the changes to take effect!

General important note! (2) in order to compile, install or even load modules, root privileges might be required

Albeit making may look successfull, even if performed from non-root privileges, the resulting module might cause the error of being invalid module, when loaded!

So, just to be sure, substitute:

make
sudo make install
depmod -a

with:

sudo make
sudo make install
sudo depmod -a

also:

sudo modprobe dvb_af903x

(Note for Infinity Nano (as of september 2010 deprecated) :or

sudo modprobe dvb_usb_af903x

respectivelly.End note for Infinity Nano )

Happy TV-viewing.
