I'm having hard time connecting the bhand.
The WEIRD thing is that yesterday it worked with no issues and I had a good time examining the controller.
but today I'm having these issues

any ideas ?

[MohamadHalwani]

It seems that the issue has to do with UEFI (BIOS) settings, I really do not know what is that but the solution in here do the job
but it seems that u have to do it each time you shut down your laptop
Any other solution is appreciated

[MohamadHalwani]

Again its not working any ideas anyone ??

[RomanRobotnik]

Is it the port /dev/pcanusb32 available?
Sometimes, when the system (kernel) is upgraded, you need to re-install the library again.

[MohamadHalwani]

You mean the pcan python ( https://github.com/RobotnikAutomation/pcan_python.git) ?
I already did all the steps, how can I check ?

Thanks for your reply

[RomanRobotnik]

ls /dev/pcan* It will show you the available devices.

Its giving no such file or directory !
Is it the peak driver missing ? because I already downloaded this from their website (version 8.8.0) and ran "make NET=NO_NETDEV_SUPPORT

[MohamadHalwani]

using the following command solved the issue
make PCC=NO PCI=NO DNG=NO ISA=NO PAR=NO
