Details:

Hello,

I'm trying your code. The usbb2k_init() fails in usb_claim_interface(). The
err number is err=-1 if I'm not root and err=-16 (-EBUSY) if I'm root.

I'm making something wrong! What is it?

My hardware is yealink and the alsa mixer detects it correctly.

Hello,
It's "normal", I have forgot to say that 
the device do not be clamed by de usbhid module.

I: If#= 3 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=00 Driver=usbhid

make rmmod usbhid befor launch de usbb2k_api 
(there is peraps an other method to say that the kernel do not use the usbhid
module for this Vendor=6993 ProdID=b001 but I don't know how...)

Best regards,
Olivier Vandorpe
