and in the source code:

* *Open Device* is 1st step
* If *open* can't work, there seems to be a problem with the device(driver/hardware/firmware)

```bash
# on the VME controller
# dmesg | grep -i vme
>
```
* VME driver doesn't seem to be installed

### Solution: Download & install driver

[Download driver here](https://www.awa.tohoku.ac.jp/~sanshiro/kinoko-e/vmedrv/)

#### Can't install

Run make

Run #make install

* Ensured Kernel version is 2.6
```
[root@NTUSL6 Linux2.6_Bit3_617]#  uname -r
2.6.32-358.el6.i686
```
* [USE_MODVERSIONS](https://www.awa.tohoku.ac.jp/~sanshiro/kinoko-e/vmedrv)
  * [and here](https://lkml.iu.edu/hypermail/linux/kernel/0811.1/00445.html)
* Run `cat /proc/kallsyms | grep kmalloc` instead of `cat /proc/ksyms | grep kmalloc`

* Either I set `USE_MODVERSIONS` as `0`, or set it as `1`, it can't install
