1. make sure that you have installed the latest version of the correct driver. There is one ARCNET RAW driver for plug-in cards and one for USB devices.
2. check whether the device is listed in the Device Manager. SH ARC-USB is listed there under “Universal Serial Bus controllers”, PC plug-in cards under “SOHARD ARCNET”.
3. check the device properties in the device manager:
- The appliance must be running properly.
- The driver access name for the device must correspond to the name with which your application addresses it.
- No device name may be assigned more than once.
- There must be no resource conflicts with I/Os, memory or interrupts.
Possible solutions are:
- Restarting the system
- Removing and reinstalling the driver after a new download
- In the event of resource conflicts: Check the resource setting in the BIOS, if necessary remove a hardware component that is causing the conflict
