Public bug reported:
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
00022327 winscard_svc.c:319:ContextThread() Received command:

CMD_GET_READERS_STATE from client 5
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?
