> aren't the identifiers in ENV{PRODUCT} already idVendor/idProduct? I don't know the details. From what I gather from the upstream source code, this device has a special rule to appear like this in the udev file:
Drivers/Braille/Baum/braille.c: { /* NLS eReader Zoomax (20 cells) */ .vendor=0X1A86, .product=0X7523, .parentVendor=0X1A40, .parentProduct=0X0101, Perhaps something like 1A86/7523 plugged on 1A40/0101. That being said it seems like both are generic ids, and the combination of them is not really specific to Baum devices, since one could very well plug a QinHeng Electronics HL-340 USB-Serial adapter on a Terminus Technology Inc. 4-Port HUB.
