Then I picked up a Biostar P35/ICH9 board and USB was up to snuff, I could read and write at 16X without a hiccup to this little enclosure. The burner used is a DW1655 BCGB. Now because I had unrelated issues with the Biostar, I am running a DFI board (DK P35-T2RS) which has the ICH9R southbridge, and it should exhibit similar USB throughput to the Biostar P35, but it's back to its old behavior of petering out after 12X. Has anyone else experienced this? Does DFI not know how to get USB performance right? Both boards were running fresh XP SP3 installs with the latest chipset drivers.
