My device is 0a5c:21f4 in a Lenovo Edge E135 and I think I am affected
by this bug on an up-to-date install of raring. In quantal all below
described devices worked (although not very reliably). Since upgrading
to raring only my bluetooth mouse is still working. Here's what I tried
to solve the problem:
I downloaded the Windows XP driver from the Lenovo Support Website and
extracted it via Wine. In a file
~/.wine/drive_c/DRIVERS/BLUETOOTH_Combo/Win64/drivers/btwusb.inf
I found information that suggests I need the RAMPatchFile
`BCM20702A1_001.002.014.0889.0899.hex`. I used hex2hcd to obtain
`fw-0a5c_21f4.hcd` which I placed in `/lib/firmware/`. From the output of
`dmesg | grep -i bluetooth` (see attachment), I figure that the firmware does
get loaded. The bluetooth mouse still works (as it did before). Also my phone
and a A2DP device get detected, which they didn't before. However I still
cannot connect to the latter two devices...
Is my problem related to this bug? Any suggestions to solve the problem?
