There are some known problems with the twinhan cards' linux drivers.
Manu Abraham (and to some extent me) is working on these and they
include among other this:
 * Some cards are sometimes not correctly detected, this happens rarely
and a fix is available that makes it happen very very rarely
 * The signal quality numbers are incorrect except for "has lock", no
fix is currently available but it is supposedly a simple fix. (Manu: I
very much like to do this if you have some documentation for me to use)

The remaining issues have little interrest to people not using CA
modules. These issues are:
 * i2c communication errors causes issues causes decryption to stop or
drop out for a while when running for some time.
 * The cam interface is incomplete (only app info and ca_pmt supported
at the moment, other things, like mmi menus would be of interrest)
