Hi linux-usb community,
By reading document "USB HID Usage Tables" version 1.12 dated
10/28/2004, it seems that section "15 Consumer Page (0x0C)" only
supports Speaker Mute (usage id = 0xe2), and section "14 Telephony
Device Page (0x0B)" supports Phone Mute (usage id = 0x2f).
It looks like Windows USB host supports this Telephony Usage page (0x0B)
above.
I can get USB-HID Consumer usage (vol+, vol-, speaker mute) working by
using usb hid gadget. I gave a try of Telephony Usage Page and Phone
Mute a try, but no success.
Anyone tried and got Phone Mute working?
Is this Phone Mute the right approach to support Microphone Mute (rather
than Speaker Mute)?
Thanks.
