Subject: [b43] usb device disconnects automatically after 1s

Hi,
I have just upgraded to 2.6.38 and discovered that I can't use my wireless
device (BCM4312 802.11a/b/g). I press Fn + F2, the bluetooth led lights
and after a second it turns off by itself. In dmesg I'm seeing the following:
[ 88.167212] usb 1-2.2: new full speed USB device using ehci_hcd and address 5
[ 88.782330] usb 1-2.2: USB disconnect, address 5
I switched to 2.6.37 until I'll have some time to bisect this. In the mean
time I have attached the output of lspci, interrupts and dmesg.
Thanks,
--
Mihai Donțu
