Fix: GrandVision 360 AIO GUI hang
Bug: GrandVision (87AD:70DB) was incorrectly classified as an HID/LED device, causing 9 timeout cycles on GUI startup (each ~5 seconds). The GUI was extremely slow or appeared frozen.
Root cause: The device reports bInterfaceClass 255 (Vendor Specific), not HID. It uses a raw USB bulk protocol (USBLCDNew) that we haven't implemented yet.
Fix: Removed 87AD:70DB from the HID device list. The GUI will no longer hang on startup for users with this device.
Note: LCD frame sending for GrandVision devices is not yet supported — a new raw USB bulk protocol implementation is needed. This is on the roadmap.
