I have a Windows program that is collecting tons of data from 5 devices that are connected from Windows through USB, but using a virtual com port with FTDI chip on the device. So for example I have COM1, COM2, COM3, COM4, COM5 that I'm sending data too. I'm sending tons of data, test is running for 1-7 days with little pausing.
I have found that I'm getting BSOD / PC crashes, usually from the FTDI COM port driver, ftser2k.sys . I've updated the driver to the latest, and all other drives to the latest.
Originally, I was trying to do 10-15 devices, but that would never work. With 5 devices, I can get it to work occasionally. I'm also going through a USB hub.
Any other ideas to solve this instead of reducing number of devices testing in parallel? I would really like to be able to test at least 5 at a time.
