USB-AD16F (USB DAQ Card) with cdc-acm

[JSalzi]

Hello

For a few days I have attempted to get this DAQ card running: http://www.bmc-messsysteme.de/us/pr-usb-ad16f.html

The manufacturer has been unhelpful and have not provided any possible solutions. Below is a description of my system and the daq card. Below I have also included information regarding testing that I have performed and debug data.

I now have no idea what to try next. I would apperciate any suggestions...

Thanks!

- After plugging the card into my system dmesg:

[ 96.376146] usb 3-1: USB disconnect, address 2
[ 98.912059] usb 3-1: new full speed USB device using uhci_hcd and address 3
[ 99.104455] usb 3-1: configuration #1 chosen from 1 choice
What the manual says:

Under MAC OS X, FreeBSD and Linux, driver installation is not necessary.Some more infomation I found in the programmer manual from the library (sorry just in german):

Das USB-AD bzw. die USB-PIO implementiert die CDC Klasse als ACM. Für diese Geräte bietet Linux einen entsprechenden Treiber an, so dass die Geräte direkt von Linux unterstützt werden, wenn das Kernel entsprechend konfiguriert ist.That means: The card implements the CDC class as ACM. For this type of hardware Linux has driver if the kernel is configured correctly.

What I have already tested:

1) Loaded cdc-acm via modprobe -> no effect
2) Loaded cdc-acm via modprobe and added new id with echo "0x09ca 0x4132" > /sys/bus/usb/drivers/cdc_acm/new_id -> dmesg:

[ 299.218265] usbcore: registered new interface driver cdc_acm
[ 299.218410] cdc_acm: v0.26:USB Abstract Control Model driver for USB modems and ISDN adapters

[ 300.332359] cdc_acm: probe of 3-1:1.0 failed with error -22
3) I downloaded the source for the kernel, edited the file cdc-acm.c and added the following to the usb_device_id acm_ids[] struct:

{ USB_DEVICE(0x09ca, 0x4132), /* BMCM USB-AD16f */
.driver_info = NO_UNION_NORMAL, /* has no union descriptor */
},After rebooting with the new kernel dmesg:

Instead of going through all the trouble with your current daq card, just purchase a USD DAQ system from Futek Instruments. Their products are really easy to use. It comes with their own program, but if want to use another program, they will provide the drivers. Browse through their USB DAQ products at www.futekinst.com, they have a lot. But if you are looking for something more specific, they will design one for you.

Hello JSalzi,

unfortunately I have received this thread so late ...

As far as I know it should work without any hazzle if there are some minor things in mind ... login as "root" and do check the rights ...
Please read the manual every line ... we are not able to provide the complete path for all linux, unix, ubuntu, kernels ...

If you read the manual (http://www.bmcm.de/us/dld.php?action=getdld&fileid=UM-LIBAD4&version=4.5&lang=en) (Libad) very carefully you will recognize the sytem is not named "USB-AD16f" ... it has to be called "usbbase" ...

Please refer the (german) forum: Ubuntuusers (http://forum.ubuntuusers.de/post/2650735) ... summary: "everythings works well" :)

So please think about *unhelpful* and let me know or resend your hotline request by email to hotline@bmcm.de

You're right, I have received an answer after more than 2 years. I really have to think about *unhelpful* support ;-)
Just kidding... I can't remember exactly what the problem was, I no longer work in this project (not even for that company). The only thing I can say is that it worked somehow in the end. Maybe I got help from your technical support - maybe not. I can't say that after 2 years.
