Can't find iCE FTDI USB device

[rnpatra]

When I am running in ubuntu 20.04 $ 'iceprog /obbbb.bin' getting following error.
init..
Can't find iCE FTDI USB device (vendor_id 0x0403, device_id 0x6010 or 0x6014).
ABORT.

Could you please help to fix the issue?

I had a similar problem in Ubuntu 22.04 LTS. When executing iceprog from a root shell (e.g. using sudo su) it worked with an Lattice iCE40-HX8K board.
