Hi Lu, > I am having trouble to make my headset work in my new W510, it works fine in an > T61, with has almost identical software and setup with the new W510. The only > difference is I am now using a pure 64 bit system, while the old T61 is a 32 > bit one, and the bluetooth chip is different. the id of the chip in T61 is > 0A5C:2110, while W510 has a chip from Broadcom with id 0A5C:217F. I noticed > there is a SCO fix for 0A5C:2110 in btusb.c. I tried to copy the line and > change the id to 0A5C:217F, but nothing changes. The headset can pair with the > laptop with no problem, but there seems to be no data transmition.
