gs_usb does not support set_bitrate() for some Candlelight devices

Describe the bug

Cannot set bitrate for some Candlelight devices. I'm using MKS CANable V2.0 Pro board with Candlelight firmware.

To Reproduce

Demonstrated here on an interactive session:

>>> import usb
>>> import can
>>> dev = usb.core.find(idVendor=0x1d50, idProduct=0x606f)
>>> bus = can.Bus(interface='gs_usb', channel=dev.product, bus=dev.bus, address=dev.address, bitrate=1000000)
>>> bus.gs_usb.set_bitrate(1000000)
False

Expected behavior

bus.gs_usb.set_bitrate(1000000) returns True.

Additional context

OS and version: Windows 10
Python version: 3.9.15
python-can version: main (@d40915ca)
python-can interface/s (if applicable):

The board works perfectly fine in Linux / SocketCAN, bitrate can be set through ip link command as is usual with native SocketCAN devices.
