I just tried and the 30 sec fix doesn't matter, with or without it applied USB is still unstable. I think the problem is that when the BT firmware isn't available, the IOBluetoothHostControllerTransport tries to load Bluetooth every 5 seconds and after each unsuccessful try it resets it, sending all USB devices on the same hub to hell with it. See the attached Console log showing two repetitions of the problem (BTFirmwareUploader missing, 30 sec fix off). My USB mouse didn't work exactly during the BT reset phase (23:34:33, 23:34:39).
Based on your testing/results, I concur. And it seems like something new in Yosemite.
I'll try to change BTFirmwareUploader for IOath3kfrmwr and see what happens, although I think I tried last week and the problems were still there. Does IOath3kfrmwr have to be installed in /S/L/E, or is EFI/Clover/kexts enough?
I don't use IOath3kfrmwr anymore as I don't have BT, so I've never tested with Clover. I don't really use EFI/Clover/kexts except for kexts which are used to boot installers or recovery partitions. I prefer to install to /S/L/E, where they always work.
