Hi Eugene,
USB Bluetooth module by Foxconn International, Inc. (USB IDs: 105b:e065)
is based on BCM43142A0 chip by Broadcom. This module can be found, for
example, in Lenovo B590 and a few other laptops.
This device requires firmware update to be operational, so this patch
adds a quirk for it.
With the firmware properly converted and placed:
Bluetooth: hci0: BCM: patching hci_ver=06 hci_rev=0000 lmp_ver=06
lmp_subver=210b
Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=00ac lmp_ver=06
lmp_subver=210b
From the output of usb-devices:
T: Bus=01 Lev=02 Prnt=02 Port=03 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=ff(vend.) Sub=01 Prot=01 MxPS=64 #Cfgs= 1
P: Vendor=105b ProdID=e065 Rev=01.12
S: Manufacturer=Broadcom Corp

I: If#= 3 Alt= 0 #EPs= 0 Cls=fe(app. ) Sub=01 Prot=01 Driver=(none)
Tested on Lenovo B590 with kernel 4.0.1 and 4.0.3, x86_64.

I am wondering if want to use USB_VENDOR_AND_INTERFACE_INFO instead. We already have a Foxconn entry. Is Vendor ID 0x105b also for Foxconn. Or is this actually Lenovo?
Looks like there is currently only one device with vendor ID 0x105b,
this one.
The USB IDs database (http://www.linux-usb.org/usb.ids) contains only
the following for that vendor ID:
105b Foxconn International, Inc.
e065 BCM43142A0 Bluetooth module
On the other hand there is a dozen of entries for Foxconn / Hon Hai
(vendor ID 0x0489) there. Btusb already handles these, it seems.
Because of the unusual vendor ID, I thought, using USB_DEVICE() would be
more appropriate, at least for now.

Marcel

Eugene
