Hi Kjetil,
Thank you for your reply.
From the first, this phenomenon occurred in the Headset-board created at our company.
Therefore, I thought that it was a problem of the board of our company at first.
However, a circuit is carried out based on CC8531_USB_Dongle_2_1_1_shematic.pdf, and is made, and the circuit of the portion of USB is completely the same.
Therefore, it is not only one board which was checked at our company.
The phenomenon was altogether the same at every board.
I think that I am not an individual problem of a board.
In addition, there is an item of USB descriptor in PurePath Wireless Configrator.
Although I was using this item by Standardheadset now, I changed this into HS1Headset.
However, the phenomenon did not change.
For example, is there any place which can change a setup into others by USB relations?
Best regards.
