Hello everybody.
I just want to say .Don't loose
your time with just another USB
chip .I had the opportunity
of using the FTDI chip.
IT is a little wonder..
you can interface it with anything
and the soft is free .
LINUX and MICROCRAP(SOFT) drivers free!!

how much of the USB data rate is lost in this conversion?

Where can find/buy the FDTI?

Has anyone tried the ftdi 245 (USB to FIFO) device? Is it true you can use the same software drivers as for the 232 (USB to serial) part?

Does exist any solution which do not need to instal any SW into PC?
Only any "black box" with cable

Cypress has two serial-to-USB references designs :smile:

How about PL-2303? Does anyone use this chip before? Try **broken link removed**. As I know, there is no this kind of class driver in USB spec., thus the driver installed is necessary.

I heard that on Mac those USB-RS232 converters encounter some problems. Anybody has experienced that too?
