Hi Oliver, I tested the suspend/resume support with my Yealink USB-P1K doing the following: * Suspend to RAM: The device suspends properly, I hear the audio subsystem turning off while the display keeps its current state. Apparently the USB root hub gets reset during suspend/resume according to the kernel log. Then after resume the input events are generated again and the display can be updated. I noticed however that the display is reset to its default text, possibly because of the USB reset? Anyway, I appended a filtered kernel log about this scenario below. * Suspend the device by "echo suspend > power/level" Works too with the difference that the display is not modified during resume. Note that during all my tests the input device was opened when the device got suspended, i.e. I did not try to explicitly open the input device only after resume. Neglecting this missing test case I would say your code works fine! Regards, -Thomas PS: Here is some part of the kernel log generated by suspend to RAM + resume: > cat yl-suspend-resume.txt | grep -i 'yealink\|5-2\|usb5' yealink 5-2:1.3: suspend usb 5-2:1.2: suspend usb 5-2:1.1: suspend usb 5-2:1.0: suspend usb 5-2: suspend yealink: urb_ctl_callback - urb status -2 usb usb5: suspend, may wakeup usb usb5: root hub lost power or was reset usb usb5: resuming usb 5-2: resuming usb 5-2:1.0: resuming usb 5-2:1.1: resuming usb 5-2:1.2: resuming yealink 5-2:1.3: resuming Restarting tasks ... <6>usb 5-2: USB disconnect, address 4 PM: Removing info for usb:5-2:1.0 PM: Removing info for usb:5-2:1.1 PM: Removing info for usb:5-2:1.2 PM: Removing info for usb:5-2:1.3 PM: Removing info for usb:5-2 usb 5-2: new full speed USB device using uhci_hcd and address 5 usb 5-2: not running at top speed; connect to a high speed hub PM: Adding info for usb:5-2 usb 5-2: configuration #1 chosen from 1 choice PM: Adding info for usb:5-2:1.0 PM: Adding info for usb:5-2:1.1 PM: Adding info for usb:5-2:1.2 PM: Adding info for usb:5-2:1.3 input: Yealink usb-p1k as /devices/pci0000:00/0000:00:1a.2/usb5/5-2/5-2:1.3/input/input8 usb 5-2: New USB device found, idVendor=6993, idProduct=b001 usb 5-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 5-2: Product: VOIP USB Phone usb 5-2: Manufacturer: Yealink Network Technology Ltd.
