Hello,

As this ticket has been discussed internally , this is just to add the information as reference

As you might know, we have 2 kind of driver releases:

• Specific FP68 (Feature Pack 68) releases like the one you were using
• MGPL driver : Generic FP92 releases, which include less features, but still fit to many customer needs.

Could you please try compiling the driver ?

Regards,
