Anybody knows, whats happened?

I have following issue:
----
my IR2BTci has worked several years now, but yesterday it stopped to work.

1) After power on, it flashes red led once.
2) No leds will remain on, even if using IR remote, if USB Power sense cable is disconnected.
3) If USB power sense to PS3 is connected, IR command LED flashes and the otder is on (should be ok). But no command transfer to PS3 happens.

I have faced sometimes before, that USB Power sense was unable to turn PS3 off, of on. Normally, restarting PS3 and/or IR2BTci helped. This is not the case currently.

PS. I dont have upgraded PS3 long time - basically it still uses firmware that enables dual boot.

Any ideas?
My feeling is, IR2BTci has lost bluetooth radio?
