Ok,
 
The problem is I don't know what kind of information I can give.
 
What I can say is the transfer takes 10 minutes via usb to serial instead of 30 seconds via the standard DB9 connector.

I'm trying to use usb to serial converter, the data transfer works but it's very very slow.
 
I use FTDI converter with kernel 2.6.25-r7 build in driver.
 
How could I trave where the problem comes from?

Unless you give more information one might assume that your slowness is only that inherent in a serial connection.
