September 17, 20232 yr So I have a r730xd and I needed to add a couple USB ports so I grabbed PCIe To USB Card. I've got 2 USB to serial adapters attached to it and I just need to ask the stupid question. How do I find what tag they are associated with as they go to my two MD1200s for fan control. I had this working on my previous setup so I know the cables are good. I'm just wondering if theres a driver or something I need to install or how do I find the tags. On the last one it was set to /dev/ttyUSB1. Appreciate it guys and I hope you can help me.

Does this show anything? root@computenode:~# ls -l /dev/serial/by-id total 0 lrwxrwxrwx 1 root root 13 Sep 16 20:40 usb-0658_0200-if00 -> ../../ttyACM0 lrwxrwxrwx 1 root root 13 Sep 17 08:06 usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_XXXXXXXX-if00 -> ../../ttyACM1

September 17, 20232 yr Community Expert Just now, TheIlluminate said: if you mean ls -l /dev/usb/by-id. same thing. no command lsusb
September 17, 20232 yr Community Expert Which os vers are you running? I would expect the usb serial adpaters to show in lsusb. Are you able to try on a port not on pci card to see if they show?
September 17, 20232 yr Author I think its that one. On a side note how do i translate info from that in to figuring out what goes here: /dev/ttyS1

September 17, 20232 yr Author Honestly didn't even think to check for that...well crap. Sorry for the stupid question and thanks. You wouldn't happen to know a PCI to USB card that actually works would you?
