sg1 is a character device, not a block device. sg1 is the HID device
in the composite device, where I need the mass storage device, which
is a block device.

Just make sure you have the usb parts, scsi parts, fs parts, et cetera or it wont work.  If you have other usb storage devices that do work, then you're probably good in that department.

It is not listed in /proc/partitions.

It is not listed in /proc/devices (as far as i can tell, there are a
bajillion sd devices in there that appear to go to nothing)

There are no /dev/ub*

There are /dev/usb*, if that's what you meant, but they are all
character devices.

I DO have another USB drive that appears as sda. this one, however,
does not appear at all. For clarification, here's
/proc/bus/usb/devices:

The last block is the simple USB HDD enclosure I bought for something like $15.

The first is the main USB hub.

The middle one has two "I" lines, which are the interfaces. The first
is storage, usb-storage, the second is HID. Only the second one gets
nodes made, and I simply can't find the magic for the first
usb-storage device.

I know it's odd, I've never seen this before either, but i'd much
rather get this working than have to take it back.
