Title: ipac 4 not connecting on linux
Post by: r3adyplayer2 on June 23, 2020, 04:40:32 pm

I have been trying to connect an ipac4 to a raspberry pi 4 2gb running lakka. The ipac is seen in the usb device list displayed by lsusb.
Here is the output of lsusb -v -d d209:0430

The command usb-devices displays these errors

I've tried raspbian and retropie they both display the same errors. Is there anyway to fix this?

Is it listed under evtest ?

The linux distro I'm using doesn't support evtest. I emailed Andy from Ultimarc, the emails concluded that the board firmware is some how broken.
