[Linux-gpib-general] 64-Bit problems of gpib-usb-hs

[Martin O. <mar...@de...>]

Hello,

the output of 'dmesg' of the 64-bit machine looks (concerning gpib) like 
this:
>Linux-GPIB 3.2.09 Driver /usr1/scratch/linux-gpib-3.2.09/drivers/gpib/ni_usb/ni_usb_gpib.c: 
>ni_usb_gpib driver loading
>ni_usb_gpib: probe succeeded for path: usb-0000:00:1a.7-1
>usbcore: registered new driver ni_usb_gpib
>gpib: registered ni_usb_b interface

here everything seems right, and module is loaded. But later it follows:
>gpib: (debug) request module returned 256
>gpib: no gpib board configured on /dev/gpib0
[...] repeats several times

After unplugging and replugging:
>usb 1-1: USB disconnect, address 2
>usb 1-1: new high speed USB device using address 3
>ni_usb_gpib: probe 
succeeded for path: 
usb-0000:00:1a.7-1

I know that I'm nerving. Sorry for this. But can someone tell me what this 
error message means and whether/how one can cure this?

Help is really welcome.

Chears,
Martin
