#189736 - FTDI Combined Driver
Responding to: Joseph Hebert's previous message
Joseph Hebert said:
In point of fact, I use Silabs USB-UART chips and they work quite well, even for programming my processors. The trick is in the driver. In order to program my processors I need the virtual COM port driver loaded. Then I just select the COM port number as normal. But when the software on my computer needs to interact over the bridge chip I need the API driver loaded (USBExpress for Silabs). And I select the driver I want loaded by setting the PID accordingly. If the PID is EA60h the OS loads the API driver. If the PID is set to EA61h the OS loads the virtual COM port driver.

A nice feature of the FTDI chips is their Combined Driver which allows to use either the virtual comport or the DLL interface without modifying the PID.
