Dear Broadcom,

I use VMWare 26H1 in windows 10 22H2 with last windows update.

Use tp-link RT3070 usb wifi adapter windows compatible driver v5.1.22.

Then use tp-link MT7610U usb wifi adapter driver v5.1.28.

Connect 2 same model RT3070 or MT7610U usb wifi adapter to vmware 26H1 no problem.

But connect RT3070 & MT7610U not same model chipset usb wifi adapter to vmware 26H1 will blue screen.

Who know to fix this problem?

Request you to recreate the issue and share usbarb log files following below steps:-

1) In .vmx, add:
    log.fileLevel = "debug"

2) In C:\ProgramData\VMware\VMware USB Arbitration Service\config.ini (create it if the file doesn't exist), also add:
log.fileLevel = "debug"
log.logMinLevel = 140
loglevel.user.usb = 10

3) Note that you need to restart the usbarb service from service control panel after adding the option(Or for simplicity, just restart the windows machine).

4) Reproduce the issue and locate the usbarb log files in this location-- "C:\Windows\Temp\vmware-SYSTEM-xxxx"

Cute CasperPlease confirm on the steps which led to the BSOD? Plug two devices on the host, and passthrough them one by one to the VM? Or passthrough in to the VM in a very short time window?
