I recently added a USB 2.0 interface card (ADS Technologies USB Turbo 2.0) to my AMD Athlon box running Red Hat 9 and its stock 2.4.20-8 kernel. I also thought it would be nice to have an external USB 2.0 hard drive for backups and what have you and purchased some gear for that purpose as well (ADS Technologies USB 2.0 Hard Drive Kit and Western Digital 120 GB IDE Hard Drive).
The problem I'm having is that as soon as I plug the external drive into one of the USB 2.0 ports, everything freezes on my machine, and I have to power cycle to reboot. I can connect and successfully mount (RW) a Lexar JumpDrive storage device through the USB 2.0 port, and can also connect the external hard drive to one of the preexisting USB 1.1 ports.
In fact, I partitioned the external drive and created an ext2 file system on the it through the USB 1.1 port (yes, it took awhile). After partitioning and making the file system, the drive mounts (RW) just fine on the USB 1.1 port, but still freezes the computer up when plugged into the USB 2.0 port, before I can even try mounting it.
Any thoughts on how to fix this (or even trouble shoot it)?

hi,
get lastet stable 2.4.X kernel from www.kernel.org, activate usb verbose debug messages in (make) xconfig
-remember ehci usb2.0 is under develpment still.EXPERIMENTAL.
avoid via chips in future.put the card in 1st (upper) pci-slot,
disable pnp bios installed in bios, load failsafe settings.
boot with append="noacpi" or disble in bios.
test with uhci driver first, then modprobe ehci.
READ the faq and infos from linux-usb.org
give lsmod, lsusb -v, lspci -vvv and cat /proc/bus/usb/devices to the developers.
good luck, y tom
