One thing I noticed is that the 0x8187 USB ID seems to be
used for both
plain and b devices, so I suspect we're going to need
some more
intelligent probing than just basing it off USB ID. IIRC,
the endpoint
descriptions are different?
This is my /proc/bus/usb/devices entry- anybody who has a 0x8187 which
behaves like a 8187b posting theirs? You remember correctly - 8187
sends through endpoint 2, 8187b uses 4,5,6,7 and 12 (0x0c).

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.
Does anyone have an 8187b with an ProdID of 0x8187 and a Product
string that does not say 8187B?
