There is a recently-discovered issue on those systems with USB devices
that draw power more heavily. If you plug it in before powering up,
it'll be fine, just can't while the system's running. An external
drive with its own power supply should be fine. Anything plugged into
a powered USB hub is fine.

[pfSense] USB hard drive on SG-2220

[Walter Parker]

Hi,

I just plugged a small WDC USB 2.0 hard drive into my pfSense firewall as
an external, second drive and everything booted:
da1 at umass-sim1 bus 1 scbus7 target 0 lun 0
da1:  Fixed Direct Access SCSI device
da1: 40.000MB/s transfers
da1: 238475MB (488397168 512 byte sectors)
da1: quirks=0x2

But when I tried to plug in a Seagate 2TB or 4TB drive (USB 3.0), the
system crashes with a power outage and doesn't restart (even after a power
cycle). It appears as if it doesn't post because the network indicators
never start flashing and the console never shows any output.

When plugged into a full sized desktop/server running FreeBSD 10.3, it
shows:

da0 at umass-sim0 bus 0 scbus8 target 0 lun 0
da0:  Fixed Direct Access SPC-4 SCSI device
da0: Serial Number XXX
da0: 400.000MB/s transfers
da0: 3815447MB (7814037167 512 byte sectors)
da0: quirks=0x2

My first guess would be that the first drive takes less power than the
second. My second guess would be that there is some incompatibility between
the USB2.0 on the the Atom board and the USB3.0 on the drive (on the full
FreeBSD machine, the drive is plugged into a USB3.0 outlet).

If I got USB drive with an external power supply, could I use a 4TB drive
on the firewall?
