Sorry to dig up an old thread.  Anyone who may be stuck with some of 
those CH340/CH341 cables may be in luck at least if your vendor:product 
id is 4348:5523.  Someone has written a Linux driver for kernel 2.6.22.  
Hopefully it will make it into 2.6.24.  I haven't tried it myself, but 
here is a link for the adventurous:


BTW, this is only for using the cable on the Linux side (if you don't 
have any available rs-232 ports).  You still need to use a pl2303 or GWC 
UC320 cable (possibly others) on the Directv receiver side.
