Thanks for the log.
Your problem now is not with the flood of "Device removed" logs but with the RAM consumption. exact?

Do you also see the RAM consumption growing if your PC/SC application is
NOT running?

Title:
  Memory leak

Status in pcsc-lite package in Ubuntu:
  New

Bug description:
  I noticed that pcscd consumes a lot of memory (5GB after 48h since start) in one of my computers (ubuntu 14.04 64-bit pcsc-lite version 1.8.10.)
  In debug mode pcscd shows a lot of USB "device removed" notifications:

  00000102 hotplug_libudev.c:594:HPEstablishUSBNotifications() Device removed
  00001297 hotplug_libudev.c:269:get_driver() Looking for a driver for VID: 0x1D6B, PID: 0x0002, path: /dev/bus/usb/001/001
  [cut - long list of usb devices]
  00000246 hotplug_libudev.c:269:get_driver() Looking for a driver for VID: 0x03EB, PID: 0x2044, path: /dev/bus/usb/001/067

  00500341 winscard_svc.c:319:ContextThread() Received command: CMD_GET_READERS_STATE from client 5

  Flood of "device removed" messages was caused by some broken USB
  device (not card reader - CDC-ACM device), but it doesn't explain why
  pcscd allocated 5GB of memory. Is it some memory leak in pcscd?
