:confused HI
I have 3 problems. Once my disk drive LG GGC H20L HD/Blu ray reads no CD, although Viesta has recognised this. then in the device manager under other devices N.M. of coach controller code 28 and under netzwerkadapter MS 6zu4 Adapter#2 Code31. I am slow in despair.

Mistake code 28 points to a defective driver's info file.

What this is generally for a device? You should receive driver with the system supplier.
