Hi All, While testing some bluetooth stuff I noticed that a cheap clone BT USB keyboard I have, with a vid:pid of: 04E8:7021 and described as "ULAK" in its strings, will not work when combined with a CSR btusb dongle. I've 2 CSR dongles both a fake and a real one, and interestingly enough it shows the same behavior with both. I can pair the keyboard and if I type something real quick after pairing it works, but as soon as I let it idle for say 0.5 seconds it stops working. I've the feeling that the problem is that the CSR dongles are quite old and only support a subset of modern bluetooth and that the keyboard decides to switch to some low-power link mode which the CSR dongle does not understand and then the connection breaks. I also see the gnome BT status icon go away after a while and then come back again after a couple of seconds (don't remember if the coming back only happened after pressing a key on the keyboard or not), as if the broken link gets noticed after a while and then a reconnect is done, only for the link to break almost directly again. I think this is probably just a bug in the keyboard where it fails to work properly with older bluetooth hosts, but if anyone has any suggestions to try and fix this I can give a patch a try.
