content: Executive summary:Brymen 869s and the BU-86X interface** on Windows with the supplied software:no go.** on Windows with Test Controller: works.** on Linux with Test Controller:no go.Details below.I just got my Brymen 869s and the BU-86X interface. I also installed the included (seems antique) software on Windows 11.Tried to link to the DMM but I am getting a "USB adapter cable not found" error even though the DMM appears in the devices list as Superior DMM.Then I installed Test Controller in the same Windows 11 machine and it had no problem finding and connecting to the DMM.Now I try on my main Linux machine, a POP OS (based on Ubuntu) with Test Controller but it fails here and I am not sure why.Here is the log:Code:;; jSerialComm version: 2.10.3;; Start thread for: HIDv0820p0001 - Brymen BM869s;; HIDv0820p0001: Found HID: 046D C332 30 36 36 31 33 36 35 38 33 39 33 33;; HIDv0820p0001: Found HID: 046D C332 30 36 36 31 33 36 35 38 33 39 33 33;; HIDv0820p0001: Found HID: 065A 0001 48 30 30 31;; HIDv0820p0001: Found HID: 0820 0001 11 3F 02;; HIDv0820p0001: Found usb device: /dev/hidraw8;; HIDv0820p0001: Rx: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00;; Stopping thread for: HIDv0820p0001 - Brymen BM869s;; Use "Load devices" page for selecting devices to load. Most devices will only load if they are connected and ready.As you can see it starts a thread for: HIDv0820p0001 - Brymen BM869sand then stops the thread for: HIDv0820p0001 - Brymen BM869sMy Java version is java "17.0.1 2021-10-19 LTS"Is it a permission issue, something else? Any suggestions?

content: Good Morning Le_avion, My BN869S has been connected to my laptop for a couple years now and has worked from the get-go with the BU-86X interface. My laptop is using Windows 10. So maybe your issues have to do with the differencein the versions of Windows.

content: I have longer time not used the interface and the (indeed antique looking) software. For testing, I plugged in the USB adapter, started the software, linked the meter, and it works perfect under Windows 11 24H2.I also never had Problems with Windows 7 and 10 in the past.

content: Have a look athttps://www.eevblog.com/forum/projects/brymen-bc-86p-usb-adapter-firmware-with-usbtmc-scpi/The latest release of the BM869s doesn't work out of the box with BU-86X adapter.Various work around are present in that post:- simple sheet of paper between the adapter and the DMM- replacing a resistor on the adapter- replacing a resistor on the DMM- replacing the firmware on the adapterI guess you can start from the simplest one and then make a choiceLet us know the outcome.Thank you.PS I found Pulseview from Sigrok project the easiest way to log data from the BM869s.Unfortunately I am on a travel and don't have the command line ready at the moment.

content: Thank you for your reply.I not sure it is the same issue because I found that the adapter and DMM combination works fine under Windows 11 with Test Controller but the same combination fails under Linux. That's why I was wondering if it is a permission issue but I didn't find any error messages in the Linux logs.
