TVH only allows 8 USB DVB devices?
0%
Description
The device I used is the Panasonic MN88473 USB device. After testing, it can only support 8, and whether it is TVH has been restricted. Whether the user is allowed to dissolve this restriction itself. Thank you for your help.

I actually picked up 10 USB sticks, but there's no more than 0-7 adapter numbers in the system.

As @seanacro said, it's the driver / kernel issue. You should look for the problem there. Perhaps, the driver supports only 8 identical devices. Closing.
