>Description:

I inserted a BlueTooth USB adapter into a system running NetBSD 5.0_RC3
and NetBSD hung. This is repeatable.

THe device particulars are:
VID 1131
PID 1001
Rev 373
Class e0
Subclass 01
prot 01

The hang was interrupted with CTRL-ESC at bus_dmamap_sync+0x81 and that
was called from ohci_softintr+0x4a0.

System is a HP s3700z.

 Hi Darren,

 This PR was a while ago, but do you still have this hardware?

 I took a brief thinkum at the ubt code but I can't see anything obvious
 that could cause that there. I think Bluetooth USB devices are pretty
 complex as they use control, event, bulk and isoc channels and it may be
 an issue further up in ohci code (though why it breaks on attach is a
 mystery to me)

State-Changed-Why:
iain asked for feedback back in 2011. Feel free to mention you can't be bothered to test it. I can use USB bluetooth successfully as a data point.

State-Changed-Why:
Feedback timeout. Wouldn't be surprised that author simply doesn't have access to this machine after so long. Relying on my own datapoint that the driver isn't horribly broken, to assume it is probably fixed.
