lsusb should list all attached USB devices. Whether the device filesystem is auto-mounted is another issue.

emerge usbutils
lsusb

If it uses standard USB mass storage, then the kernel would support it.

If the drive has non-standard bells and whistles, then it is possible that some whistles may not work; unless it is really niche hardware, it is likely the kernel would have some support for it, but you would want to check first.

I haven't had any problem with the 5 external USB drives I have. They
are either off-the-shelf Buffalo 500GB USB drives or I've purchased 3
NexStar 3 cases and put WD 1TB drives in them. Choose a file system
that allows labeling and if you're lucky like me you likely won't have
any problems.

Good luck,
Mark
