== How to get a proper lsusb ==
As [http://erste.de/UT61/index.html documented by Ralf Burger] the [[Multimeter_cables#UNI-T_UT-D04|UT-D04]] USBHID-to-serial cable (at least the one with WCH CH9325 chip) that comes with the UT61D multimeter has some issues on Linux. Apparently you need to [http://www.lesswatts.org/projects/devices-power-management/usb.php put it into a (auto)suspend first], before you can properly use it.
Here's a script (written by Ralf Burger) which you can run before using the chip and/or doing an lsusb:
<small>
$ '''cat suspend.HE2325U.sh'''
#!/bin/bash
for dat in /sys/bus/usb/devices/*; do
  if test -e $dat/manufacturer; then
    grep "WCH.CN" $dat/manufacturer > /dev/null && echo auto > ${dat}/power/level && echo 0 > ${dat}/power/autosuspend
  fi
done

This is the lsusb ouput on Linux:
