	aptitude get install pcscd pcsc-tools
	Add the reader to libccid conf file
	<br>Without fingerprint reader: VendorID=0x0a5c ProductId=0x5800 (with: 0x5801)
	<br>Edit /etc/libccid_Info.plist and add lines in ifdVendorID, ifdProductID and ifdFriendlyName arrays

	Trying manually
	/etc/init.d/pcscd stop
	pcscd -f -a -d
	'''FAILED with ''IFDHCreateChannelByName() failed'''''

	Actually it may work but only if a card is present when pcscd is started.
	<br>See also [http://pcsclite.alioth.debian.org/unsupported.html#0x0A5C0x5800 here]

	RFID support seems not possible on Linux for now

	UPDATE: since an upgrade it's even worse, only basic retrieval of ATR works

	Should try a firmware upgrade? see http://www.natisbad.org/E4300/index.html
