[field #9] Summary: usbb2k_init() fails
[field #10] Original Submission: 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
