Re: Regression: Problem in using USB Bluetooth Dongle (Worked fine in 2.6.24.x)

Hi Brian,

At least until kernel version 2.6.24, I was able to use my USB
bluetooth dongle to download contacts from my phone. I made a jump
from 2.6.24 to 2.6.27, so I am not sure exactly which kernel version
starts the problem, but all kernels from the latter (2.6.27) now do
not work. The latest kernel I have tested is 2.6.29.2.

can you test 2.6.30-rc4 or bluetooth-testing.git. I am pretty sure that
whatever broke in 2.6.27 has been fixed by now. Some cheapo USB dongles
behaved wrongly and it was a long time not clear what caused it.

Alas, the regression is still there in 2.6.30-rc5 which I tested over
the weekend.

I also forgot to mention that, even with the kernels with the
regression, device pairing using the dongle still works.

Would a packet capture (usbmon) help? Willing to capture whatever
other debugging data that you think may help

if device pairing works fine, the I guess this is a different problem.
It could be that your USB host controller doesn't like the device. Or
you forgot to load the EHCI driver or something. Otherwise your dongle
should work fine. Since pairing works, what does hciconfig -a says?

Regards

Marcel
