However, this seems to break SieFS 0.2
(http://mirror01.users.i.com.ua/~dmitry_z/siefs/; 0.4 is broken with
Siemens x55 models): even "slink i" does not work:

There is no responce to the packet. Without the tty patch SieFS
works; 2.6.9 (where locking fixes are already applied) also works.
The bug might really be in the pl2303 driver (the 2.4 version is
missing some patches which are in 2.6.x). Will try to investigate
this further...
