# Example: Send a 8-byte challenge, read 8-byte response CHALLENGE = b'\x01\x02\x03\x04\x05\x06\x07\x08' response = dev.ctrl_transfer( bmRequestType=0xA1, # Vendor, device-to-host bRequest=0x01, # Vendor-specific command wValue=0x0000, wIndex=0x0000, data_or_wLength=8, timeout=1000 )
Note: You must act quickly as devices often exit BROM mode if they don't receive a command within seconds. authbypasstoolv6 libusb best
