I have a QuickSilver 2001 with a PowerLogix 2.0ghz upgrade.

I am unable to transfer any data from any hard drives or scanners, etc. via my FireWire ports or my USB 2.0 card.

Anything transfered over USB 1.0 works fine with either the stock ports or the USB card.

The stock FireWire ports show up in the System Profiler but do not work at all. I installed a PCI card and I can use my FireWire scanner but only scan below 150 DPI...anything higher, it will freeze. I can transfer files from my DV camcorder with the PCI card.

I also found an old internal hard drive and installed a fresh copy of 10.4 without any luck booting with it. I have another internal hard drive and installed 10.4 and the same thing happens.

I plugged the items into my PowerBook and everything works fine.

I can understand how either the USB or FireWire ports can go bad, especially if the board is bad, but both the factory USB and FireWire and and PCI card ports, seem weird, especially, since the all of the plugged in items on all of them work, I just can not run any backups, transfer files, scan large files, or repairs the disks.

I will receive an I/O error -36 when trying to drag items to the disks.

I ran Cocktail and removed the caches I could find.

I also reset everything in open firmware and pressed the reset button.

I ran the hardware test and it showed okay.

I reset the FireWire ports by unplugging.

I reinstalled the original CPU and stock RAM (and ran memtest) and it did not make a difference.
