USB Serial driver

DGona · ‎07-10-2018

Hi,

Trying to get a USB serial device to work on the intel aero. When I plug it in I see the device is recognized but not serial port is enumerated. Am i correct is assuming no usb serial drivers are compiled into the intel aero yocto kernel? I can't see any under /lib/modules//kernel/drivers/usb/serial

Trying to install ubuntu to get around this if what i understand is correct

Thanks

Dion

Hello dgonano,

Thank you for your interest in the Intel Aero Compute Board.

Could you please let me know which USB serial device are you trying to use and the output of aero-get-version.py ?

Also, if it's possible can you share more details about what are you trying to do with the USB serial device?

Thank you in advance,

Eliza

I can see the USB device obviously, but I can't see the serial port, I'm assuming the aero doesn't have the driver

Hello dgonano,

It is possible that the driver is not included in the Yocto image.

Could you please try to add the driver or try to use the usb/serial device with Aero running Ubuntu and see if the driver is included?

Looking forward to your response.

Regards,

Casandra

Confirming no USB serial drivers are included in the yocto image. This is unbelievable, very useful for embedded linux development.

Ubuntu included them and working fine using the generic kernel
