We only allow suspending while we are in the interrupt transfer stage. To suspend, we cancel the interrupt transfer and at resume time we restart it. This has been tested to work correctly on an X1 Carbon 8th Gen with suspend mode set to "Windows 10" (i.e. S0ix [s2idle] and not S3 [suspend to RAM]). With S3 suspend, the USB root hub appears to be turned off or reset and the device will be unresponsive afterwards (if it returns). To avoid issues, libfprint disables the "persist" mode in the kernel and we'll see a new device instead after resume.
