Other WD My Book "fatal error, failed to attach to device"

[pvanulden]

I was running FreeBSD 8.2 on a Dell R310. Over the holidays, I installed a fresh copy of 10.1 that went flawlessly. Very impressed with how easy it was to export/import ZFS pools, etc.

I have a couple of WD My Book external hard drives that are used for backups. In 8.2, I had no issues plugging them in and mounting the filesystem. Now, with 10.1-RELEASE, when I plug the drives in, I get the following:

I can resolve this by using usbconfig(8) to power off and then on as follows:
# usbconfig -u 1 -a 4 power_off
# usbconfig -u 1 -a 4 power_on

I am then able to mount file systems just fine on there. Is there some configuration that can be adjusted to prevent having to do this?

Thanks!
