Subject:   USB 2.0 external hard drive only 1.000MB/s transfers

Hi,

I bought a USB 2.0 external hard drive and USB 2.0 PCI card to use for
backups on my FreeBSD box but the drive is recognised as only being able
to do 1.000MB/s transfers. Obviously a USB 2.0 drive should be able to
transfer data a lot faster... I have checked my config and can't see any
issues.

Can someone point me in the right direction or see an issue with my
config? I have included a "dmesg" and "kernel config" below.

Thank you in advance for your help.

Cheers.

-Chris
