Bug Description
Summary:
Upon attaching a VLI hub device, Ubuntu 20.04 will send a SPI vendor command to the VLI hub. This is unwanted behavior that will alter our firmware in unexpected and dangerous ways --outside of normal firmware update protocol. Previous versions of Ubuntu were only allowed permission to send standard commands, not vendor specific commands.
Further Information:
1. USB device used: U3 VLI Hub, ID:2109/0817
2. Ubuntu hardware: Across all standard motherboards running Ubuntu 20.04 OS.
3. What you expected to happen: No USB vendor command, 0xC0, issued.
4. What actually happened: Several USB vendor command issued.
5. If possible, steps to reproduce error: step 1 power-on Ubuntu 20.04 OS PC; step 2 plug-in VL817 hub.
