Hello, I have an usbduxfast DAQ module but it doesn't seem to be working. The kernel module loading, the firmware loading work just fine, but tools like comedirecord and qtscope display only straight lines, for all channels, as if nothing is present at inputs! Then I made a polling test which successivelly calls comedi_data_read on all channels and which shows that the board is indeed sensitive to its inputs. However, every voltage I plug in (continuous or not) everything I get is noise (random values between 0 and 4096, in every channel)! Even if connect a humble resistor between a channel input pin and ground pin the result is the same: noise on every channel. Kernel is 2.6.11, comedi 0.7.70. What can I do, where should I start? Thanx in advance, Calin Vatavu -- _______________________________________________ Get your free email from http://mymail.skim.com
