28 Description: Meilhaus PCI data acquisition cards
29 Author: Michael Hillmann <hillmann@syscongroup.de>
30 Devices: [Meilhaus] ME-2600i (me_daq), ME-2000i
37 Configuration options:
39 [0] - PCI bus number (optional)
40 [1] - PCI slot number (optional)
42 If bus/slot is not specified, the first available PCI
45 The 2600 requires a firmware upload, which can be accomplished
46 using the -i or --init-data option of comedi_config.
