Stlink-v3 does not support USB 1.1 (wrong packet size)

If connected via USB 1.1 the maximum packet size should be 64. However the stlink-v3 sets the maximum packet size to 512.From dmesg: usb 2-1.3: config 1 interface 0 altsetting 0 endpoint 0x81 has invalid maxpacket 512, setting to 64

We tested DfuSe Demo v3.06, but it cannot find our STM32F04 (nothing can be fund). We checked the driver, USB serial device COM12 can be seen. However, STM32 ST-linke can work. Its driver is STMMicroelectronic STLink virtual COM port COM8.
