Can't get USB2 driver to work with External HDD (SuSE 9.1)
I just added a 500GB Western Digital USB2.0 external hard drive to my SuSE 9.1 box and it comes up fine except it's extermely slow when copying large files. When I look in /proc/bus/usb/devices, it says the driver used for the external HDD is "usb-storage". And it says "Spd=12," which I assume means 12Mbps.
I need it to be 480Mbps (USB2), because I need to copy about 250GB of data from the internal drive to the external. I edited /etc/sysconfig/kernel and set
MODULES_LOADED_ON_BOOT="ehci-hcd"
to force the USB2 module to load before USB1, and rebooted, and it's still slow, and Spd=12 still.
What else can I try to make USB2 work?
Thanks.

Rep:
Does the machine have multiple USB ports. On some machines I have seen have like 1.0 ports in front and 2.0 ports in the back or vice a versa.
If it loads the ehci-hcd then there should be 2.0 ports. To see loaded modules use the command ' lsmod '.
Also using a gui tool like USBview which may already be installed will show a better view of what you have and where things are. Use the command ' usbview ' and see if installed. If not install a copy.
Turns out, I was misinformed by the vendor. They told me the motherboard had USB2 ports but they just corrected themselves. THere are no USB2 ports, just USB1.
