Right. But mine matches the USB vendor/product ID in the table in hid2hci.c. So even in that case, it might not support HID proxy mode, right? (I have a vague recollection of a firmware upgrade possibility using a windows program, but I may be thinking of something else; does that ring a bell with anyone?) Does anyone reading this actually have one of these elusive devices in their possession? If so I'd love to know the brand etc. and even to get a photo. I know it still doesn't guarantee anything, but it would be better than my current "random guess" approach to finding one. On the other hand, if I won't be able to get HID proxy mode to work, I need to understand some more about how normal bluetooth keyboard mode works. In particular, the kernel has some input quirks for Apple keyboards that seem to be keyed on the USB vendor/product IDs; for example, FN+UP => PgUp. These don't seem to be applied on my system, presumably because the USB ID matching has nothing to do with bluetooth devices. How is this supposed to work?
