at91rm9200 usb bluetooth problem

[Marcin Undak <mcinek@xxxxxxxxx>]

Hi.

I've got custom board based on AT91RM9200. I try to use bluetooth
dongle via usb. The dongle is detected correctly, however I get strange
error from at91-ohci driver:

at91_ohci: urb c1d8fc14 path 1 ep2in 5c160000 cc 5 --> status -62
at91_ohci: urb c1d8fc14 path 1 ep2in 5c160000 cc 5 --> status -62
at91_ohci: urb c1d8fc14 path 1 ep2in 5c160000 cc 5 --> status -62
...

These are shown when I initialize bluetooth by 'hciconfig hci0 up'
command. Despite of above error, bluetooth kinda works, but very, very
slow - I suppose it's due to broken usb transfer.

I'm using very minimal linux system, compiled myself, using 2.6.23
kernel (tried also newest 2.6.24-rc6), udev and bluez. To load linux,
I also use custom, very small bootloader.

In kernel, I've compiled of course usb support and necessary bluetooth
drivers (Bluetooth HCI). I've tried using two different dongles, on both
the same effect.

Am I missing something? Should I try older kernels?

Best regards,
Marcin Undak
