Multimeters
UNI-T UT-D04
How to get a proper lsusb:
As documented by Ralf Burger the 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 put it into (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:
$ 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
lsusb:
This is the lsusb ouput on Linux:

lsusb of slightly different cables:
There is another cable version apparently which also has the USB VID/PID 1a86:e008 ("QinHeng Electronics HID-based serial adapater"), but with slightly different lsusb output. Both cables work fine with the same code, it's unclear what the differences are (or whether they relate to the chip/hardware or to some kind of firmware or ROM).
- bcdDevice 12.00 - iManufacturer 1 WCH.CN ^R + bcdDevice 11.00 + iManufacturer 1 WCH.CN ^Q
Here the USB VID/PID are the same, but some details are different, and it advertises itself as self-powered, which it isn't.
