My device doesn't show up in /proc, but
/sys/bus/usb/devices/1-5/product shows it to have the same Product
string as yours, with a ProdID of 8187.

Is your usbfs mounted? you should have an entry similiar to this in your
fstab:
----------
none /proc/bus/usb usbfs auto 0 0
----------
and that gives you the /proc/bus/usb/devices entries. Most userland
usb device drivers (libusb - scanners, ptp digital cameras) need the
/proc/bus/usb hierachy to work.
The usb endpoint list is a functional difference between the 8187 and
8187b.
(it runs to 0c for the 8187b, and does not have a 02 entry which the
8187 uses).
My fstab entry was set "noauto". Once it was mounted, then it shows

Do I understand correctly that it might be better to check for the
existence of endpoint 02 for an 8187 device? Or would it be better to
look for endpoint 12 to set it as an 8187B?
