Indeed, this doesn't seem like a driver issue. If the JTAG is unrecognized it ends with something like "Error: unable to open ftdi device with vid xxxx, pid xxxx, description 'Olimex OpenOCD JTAG ARM-USB-TINY' and serial '*'"
Check the hardware connections. Check if the target is powered.
Maybe test with other version of OpenOCD.
