I hope you have a spreadsheet of all that. I'd smoke something pretty quick trying to remember which port has the power supply for X device.
No need. I have better than that: dev file aliases. So I have for example
/dev/crs1, the device/dev/crs1_pwr, the PSU for that device (if it's powered alone)/dev/crs1_snoop_rx, the serial cable that snoops on the device's Rx line/dev/crs1_snoop_tx, the serial cable that snoops on the device's Tx line/dev/crs1_jtag, the JTAG adapter that programs / debugs that device/dev/crs1_tilt_x, the X axis of the tilt table the device is mounted on/dev/crs1_tilt_y, the X axis of the tilt table the device is mounted onEach point to some nondescript
/dev/ttyUSB?or/dev/ttyACM?but the aliases have meaningful names, so I don't need to remember anything.That's the power of udev ๐ And also one of the many reasons why Linux is better than Windows.
Very nice!
