I have an old GADMEI USB TV BOX, in the back it says MODEL: TVR200. I haven’t use this since few years ago in Windows. I am planning to learn a little bit about Wii homebrew, so I thought if I can use my computer as display, I don’t have to go back and forth to my TV. When I plugged the USB TV BOX, the kernel display some messages about em28xx:
[ 3662.345631] em28xx #0: Your board has no unique USB ID and thus need a hint to be detected. [ 3662.345634] em28xx #0: You may try to use card=
insmod option to workaround that.

So I tried modprobe em28xx card=0 and then card=1, and then card=2, thankfully it worked with card=2. I used tvtime program to see the output of the usb tv. To make it permanent, add this line:
options em28xx card=2
to your /etc/modprobe.conf, or create a new file (any name is fine) at /etc/modprobe.d and fill it with that line. Note: audio is not working yet, but I don’t really need it right now.
