hci reset on init

[Dave Young]

Hi, marcel

Recently, I find my usb bluetooth dongle doesn't work after reboot or resume.

Kernel report (with bluetooth mouse active):

Feb 15 16:54:32 darkstar kernel: hci_acldata_packet: hci0 ACL packet for unknown
 connection handle 43
Feb 15 16:54:34 darkstar last message repeated 124 times

I fixed it by adding HCI_RESET to CSR usb id:
        { USB_DEVICE(0x0a12, 0x0001), .driver_info = HCI_CSR |HCI_RESET},

Maybe you have known that there's other reports about this on
bluetooth list as well.

Most of the ids in hci_usb.c have the HCI_RESET option set.  Does we
need to do this automaticly?  I want to know whether sending reset
request on init in hci_core.c is better, or at least the btusb driver
need these porting.

What's your opinion?

Regards
dave
