To find the latest driver for your computer we recommend running our Free Driver Scan. I've update the drivers for my main-board (ALiveNF6G-GLAN) with the files. I'm really frustrated by this problem because I suspect it might be the 6150SE) and chip-set (nForce 430) (v15.49) from here, but the PCI Serial Port driver is still reported as not installed.
Deleting the device (and letting Windows re-detect it) doesn't work either.
