Some ECU programmers are sensitive to timing. Add usb.quirks.device0 = "0xVID:0xPID skip-reset" to the .vmx (replace VID/PID with your device IDs). This prevents VMware from resetting the USB device on connect.
While VMware is the best for USB device compatibility, here are two alternatives: winols 451 vmware
Vanilla WinOLS 451 on VMware can feel sluggish, especially when rotating 3D maps. Apply these tweaks: Some ECU programmers are sensitive to timing
Successful implementation of WinOLS 4.51 in a virtual environment requires careful resource allocation. Unlike standard office applications, ECU mapping involves database lookups, checksum calculations, and real-time data visualization, necessitating robust virtual hardware. While VMware is the best for USB device
Inside the VM:
