Re: [Bluez-users] NEC usb bluetooth support

Hi Marcel,

Yup i do have an entry (see below), and i've managed to get it to load, but by
hacking the hci_usb.c to remove the lines

 	/* Check number of endpoints */
	if (intf->altsetting[0].desc.bNumEndpoints < 3)
		return -EIO;

It looks like since there's multiple interface descriptors for the device (see
attachment), and bNumEndpoints is only equal to 3 in one of them, then the test
fails and returns EIO. I don't know if this check should be removed altogether since
we subsequently iterate thru all the interfaces to get the endpoints.

hciconfig shows me 2 interfaces - is this correct ?

Hi Mitch,

Just bought one of these, but doesn't seem to work on 2.6.0-test11.
syslog spews out:

  Bluetooth: HCI socket layer initialized
  Bluetooth: HCI USB driver ver 2.4
  hci_usb: probe of 7-2:1.1 failed with error -5
  drivers/usb/core/usb.c: registered new driver hci_usb

Tried adding the device id's to hci_usb.c in vain.

Any ideas to get this beast working ?

your dongle should work out of the box. Have you tried 2.4.23?

Do you have a /proc/bus/usb/devices for us? It should show you something
like this

	T:  Bus=04 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  7 Spd=12  MxCh= 0
	D:  Ver= 1.10 Cls=e0(unk. ) Sub=01 Prot=01 MxPS=64 #Cfgs=  1
	P:  Vendor=0a12 ProdID=0001
	C:* #Ifs= 3 Cfg#= 1 Atr=c0 MxPwr=  0mA
	I:  If#= 0 Alt= 0 #EPs= 3 Cls=e0(unk. ) Sub=01 Prot=01 Driver=hci_usb
	E:  Ad=81(I) Atr=03(Int.) MxPS=  16 Ivl=1ms
