VN5640 Driver Not Loaded when Connected to USB3.0 Renesas Controller µPD72020X
VN5640 driver is not correctly loaded if
- a VN5640 is connected to a USB 3.0 host port which has a Renesas controller µPD72020X and
- a driver update is done.
This problem is caused by an error of the corresponding Renesas USB 3.0 host controller (latest driver version: V22.214.171.124).
Older Renesas driver versions tend to have the same problem.
Connect the VN5640 with an USB 2.0 cable to the Reneases USB 3.0 host controller port for updating the driver. Afterwards the VN5640 can then be connected with an USB 3.0 cable and used without limitations.
Use another USB 3.0 host controller (e.g. Intel or another Renesas controller)
