LINUX_CAN_Read_Timeout() gives CAN_ERR_OK without connectio

[tymbusku]

Hello,

I use PCAN-USB. When I plug in the USB-Adapter, but don't connect it via CAN-Bus with the motor, the linux function LINUX_CAN_Read_Timeout() sometimes gives me back CAN_ERR_OK anyhow.

Kernel is 2.6.23.1-42.fc8-i686
Driver version is 7.4

What cause could this have? Can I solve this somehow?

CAN_ERR_OK

means that the function was called succesfully - so you should check the CAN Msg Structure which Data type you receicev (real CAN ot maybe a Status )
