The external USB harddisk I'm using works fine with ehci (VIA VT6202 USB
2.0 controller) on 6.2-PRERELEASE amd64:
addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), VIA(0x0000), rev 1.00
port 1 powered
port 2 addr 2: high speed, power 100 mA, config 1, Mass Storage Device(0x3507), Prolific Technology Inc.(0x067b), rev 1.00

The only problems I ever had wer with the firewire interface, not
USB. But I don't use amd, and I'm using GEOM_ELI encyption.
If amd doesn't work well with ufs, would using glabel be a workaround?
