[Bluez-users] hid2usb error

[Alexandre Ghisoli]

Hi there, 

I've the Logitech diNovo Bluetooth kit, and try to use it as BT device.
So, i've bluez-libs2 & bluez-utils2 to use the hid2hci tool to pass my
Logitech USB HUB to an Bluetooth HUB.

Kernel 2.6.2-mh
hid module loaded.

Running the hid2usb give :
Invalid argument ...

After some investigations, it appear that the following line return the
error (around line 240) :

err = send_report(fd, rep1, sizeof(rep1))

at the 2nd byte send (0xff 0x80)
Anyone can help me, plz ?

Regards

	--Alexandre

you need a patch for the USB HID driver to send multiple bytes. I think
it is not included so far. Must be pending in Greg's list.
