Hi, I have a Brymen 869s + BU86x (bought together in jan-2017), that work reliably under Win 10 on two different computers (an aging self-built desktop built around an i7-2600K, and an ancient Acer Aspire 1810tz).
However, on two different Win11 laptops this combination will not run (with a one-time exception, below).
The main (test) Win11 laptop is a HP Elitebook G7- i5 with Win11 Pro. As alternative I tried my wife's Surface Pro 7.
The datacable shows up with VID 0820 and PID 0001 in Device Manager, and identifies under devices --> other devices as 'Superior DMM'.
Note: I see two device IDs:
USB\VID_0820&PID_0001&REV_8603
USB\VID_0820&PID_0001
In the Brymen Bs86x software (downloaded from the site, version 6.0.0.3s) I get error [E9015] USB Data Cable not found.
I have also tried Test Controller. It seems to find the cable but fails to communicate with it (Test Controller works on a Win10 computer with this hardware). From the debug mode:
;; HIDv0820p0001-81727: Found usb device: \\?\hid#vid_0820&pid_0001#6&27b953b7&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}
;; HIDv0820p0001-81727: Comm failed
;; HIDv0820p0001-81727: RxHID:
;; Stopping thread for: HIDv0820p0001-81727 - Brymen BM869s
Other things I tried:
- run as admin (I normally run in a user account)
- set compatibility mode (to Win7)
- switch off 'Allow the computer to switch off this device to save power'
One-time exception: Earlier tonight the Brymen software was able to connect one time in the Brymen Bs86x software. After I took out and reconnected the USB plug I was no longer able to connect, also not after a restart.
I've already gotten feedback on a Dutch forum that this combination works for other people under Win11.
I'm not much of a Windows troubleshooter, and out of options. Help very much appreciated.

Thanks for the link.
The plot thickens: With Sigrok (version 0.7.2) it works (both with and without admin rights).
Any thoughts?

Sounds like bad drivers. Try uninstalling from device manager, then reinsert to reinstall.

The drivers are the standard Windows drivers for HID devices. Screenshot attached, but I don't have high hopes this will solve the issue, especially since a second Win11 PC has the same issue.
I'll try anyway over the weekend.
