The highest power draw listed by
tlp on this Dell E7250 at idle is the process
pcscd which is for smart card readers. This laptop has a smart card reader, but I do not use it.
Is there a power saving option to avoid this? Or in the worst case, an option to disable the device?
From the devices tab in
tlp the Broadcom 5880 USB device is constantly drawing power:
lsusb identifies it also:
Bus 001 Device 005: ID 0a5c:5800 Broadcom Corp. BCM5880 Secure Applications Processor
From searching online it indeed corresponds to a smart card reader.
