I have the same problem since 02/10.
I am using Win7 Ultimate.
The weird thing is there is no sign of updated FTDI drivers in Windows update...
I am also using the latest FTDI drivers 2.12.00
I have uninstalled Update KB3001554 because there where people having problems with this driver but it didn't solve this issue.

Apparently there was a bug in the Windows USB-to-serial driver usbser.sys

Basically using the FTDI USB to serial uses the FTDI version of the virtual COM port driver, not the Microsoft built in usbser.sys which has a known bug.
