Yes, you are right. After kldload'ing the ehci driver manually, it
automatically detects my SanDisk USB flash drive. I proceeded to
installation and got successful with it. However when booting after
installation, it stops somewhere while mounting the device. Below is
the error encountered.
Mounting root from ufs:/dev/da0s1a
no disk named 'da0s1a'
ffs_mountroot: can't find rootvp
root mount failed: 6
Manual root filesystem specification:
<fstype>:<device> Specify root (e.g. ufs:da0s1a)
? List valid disk boot devices
panic Just panic
abort Abort manual input
Possibly valid device for 'ufs' root:
"cd" "md" "ad" "acd" "mfs"
Here, I typed "?" where it doesn't show any "da" device

Panic is displayed when I invoked "abort" or "panic". Is this a bug?
