Problem with CDM driver
« on: March 19, 2018, 11:12:23 AM »

Hi,
i have downloaded the CDM drivers package from your site. I'm using the
CMOD A7 35T Digilent board that uses an FTDI FT2232HQ USB-UART bridge.
All work perfectly but sometimes when i connect the board to pc there is a
conflict with driver i mean.
In detail:
- I connect the board to pc
- in device manager i can find a COM port and two USB Serial Converter
- the driver is updated and work perfectly but if i try to communicate
with board using a C program that work with ftdi.h and ftdi.dll library
nothing happen.

This problem appear randomly,in the 90% of cases the C program work
correctly but sometime happen the issue and i need to open device manager
and disinstall USB HUB and refresh hardware device, in this way the USB-HUB
is installed again and then i can communicate with board using my C
program.

I realy don't undestand why this happen. Can you help me pls?

Regards Stefano
