| This test uses servo to connect/disconnect servo USB hub before and |
| after events like reboot, login, suspend, resume etc. |
| |
| The test fails if |
| - device is pingable when suspended |
| - wrong action passed through action_sequence flag |
| - USB detected peripherals are different than expected |
| - there is no servo board attached |
| - USB peripherals checks(usb_checks below) on command line fail |
| Other detection checks can be added for each peripheral |
| |
| Set of four USB peripherals plugged |
| - USB headset |
| - USB HD Webcam - should be Logitech HD Pro Webcam C920 |
| - USB stick with four partitions named ExFAT Ext4 FAT NTFS |
| - USB mouse |
| - USB 3G modem |
| - USB SD card reader(one microSD card plugged) |
| - USB connected phone(optional) |
