Hello everyone,
my issue is when i connect an ardino micro pro to any of my USB ports the arduino IDE finds it immediately(lists it in tools->ports) as a valid option, but when i connect an arduino mini pro it doesn't find it in any way, in the list of valid ports there's only the arduino micro pro listed, when i try to connect them separately it still finds only the micro board. In device manager in the COM ports section it lists both but the faulty one (mini) as Profilic USB-to-serial comm port with a little warning sign on the icon, and the good one (micro) as arduino leonardo, no warning sign, i checked the cable that connects the mini to a comm port and know for sure that it's working properly, also i tried a different mini pro board but still the same result.
Any help would be greatly appreciated!
Hi j0rd3y,
the two board have complete different hardware characteristics.
you are meaning this ArduinoBoardProMini ?
than you need a TTL-Serial to USB adapter.
and yes - with theses adapters there are some cheap-not-everytime-working devices out there...
i had a Profilic USB-Serial adapter and did not get it to work on windows7.
but that has nothing to do with Arduino!
this is the problem with the Profilic drivers.
sadly the Arduino USB Serial Light Adapter is discontinued.
this one worked great. (never head problems with these.)
a real FTDI adapter should also work well - but there are counterfeit ftdis on the market - so if you buy on use a reliable source
for example:
FTDI Cable 5V; SparkFun FTDI Basic Breakout - 5V; FTDI Serial TTL-232 USB Cable; FTDI Friend + extras - v1.0

I have a USB to serial converter cable, which i thought was the problem, but it turned out it was the driver, when i uninstalled it and installed it again it started working, but when i updated it, it stopped again 
The moral of the story is, don't update your drivers !
Cheers!
never change a running system 
drivers are a world of its one....
as i have written - my experience with the prolific drivers are long searches for what whent wrong...
in the end i used a ftdi adapter

Ps: pleas add [solved] to your first post title.
