Hi. "error -84" is a CRC error, suggesting data corruption. It sounds like you tried everything I would have suggested, other than trying a different USB cable. However, this problem sounds exactly like another problem somebody recently reported which was solved by replacing the USB host controller, which you said you tried and it didn't help. What brand was the PCI controller, what chipset does it use, and what host controller driver does it use? (Most if not all USB controllers with a chipset not made by Intel and VIA are OHCI, not UHCI, so make sure you were using the right host controller driver.) What symptoms and error messages (if any) did you see when you plugged the PSC 22xx into the PCI host controller instead of the motherboard host controller and tried running your tests?
