Hi,

we are trying to connect throw usb with other micro that not support more than two usb descriptors.

BGS5 generate two usb descriptor and works fine but EHS5 generates seven and this micro is not able to manage it.

Thanks

Hello,

I have verified that it is unfortunately not possible for EHS5 to reduce the number of USB descriptors. Maybe RS232 interface could be a solution instead.

Thanks,

the RS232 interfaces are already used for other purposes.

If there's any RS232 interface connecte to your processor you coud think about multiplexer. But if not you probably need some hardware change.

Hi,

We have a lot of modem working today so is not possible to do a hardware change.

Thanks.
