otverio2015: OSError: [Errno 25] ioctl failed

[doofy]

Changed permission with chmod o+rw for /dev/sda but cannot read (neither info nor dump work)

Help! :)

Has something tried to mount the drive? I haven't seen this happening before, and errno 25 is "Inappropriate ioctl for device" which is surprising.

I won't be able to test this until next month unfortunately :(

I am experiment with Java and connecting to this device with it and I noticed that Linux kernel attaches to it, so before claiming Verio interface I had to detach the kernel driver. You might need to do something similar here.
