[Bluez-devel] hci_usb question

[Paul Ionescu]

Hi,

My CSR BT USB dongle is working fine, but usbview shows it with red color.
That usually means that no driver is installed for it, or some error.
It is only me, or this is general behavior ?

Also hci_usb creates 3 USB interfaces for my BT dongle.
What are these 3 USB interfaces for ?

Thanks,
Paul

I just looked in the specs and some other places and found it:

One bluetooth bulk endpoint
One bluetooth isochronous endpoint
One firmware upgrade endpoint

And it seems that hci_usb only claims bluetooth USB Wireless Controller
class E0, and firmware upgrade which is USB class FE is left unclaimed.

So, if hic_usb would claim also USB class FE, then it would not appear as
red in usbview.

Thanks,
Paul

ask the author of usbview or check its source code. I don't know what
red means.
