SeeedBus does not transmit bus messages

### Describe the bug
SeeedBus can be used with the logger and viewer scripts but data transmitted via it does not seem to actually reach the canbus.

### To Reproduce
I have both a Kvaser Leaf and a SeeedStudio adapter connected to the same bus which is connected to an motorcycle ECU.
If use can.logger to sniff the bus with seedstudio and transmit the commands below, the seedstudio adapters records the messages and the response. If I reverse things and log with kvaser and transmit with seeedstudio, nothing shows up in the logger at all.
```
import can
# with can.Bus(interface='kvaser', channel=0) as bus:
with can.Bus(interface='seeedstudio', channel='COM12') as bus:
msg = can.Message(arbitration_id=0x18da10f1, data=[0x02, 0x3e, 0x80, 0x55, 0x55, 0x55, 0x55, 0x55], is_extended_id=True, is_rx=False)
bus.send(msg)
recv_msg = bus.recv(timeout=1.0)

msg = can.Message(arbitration_id=0x18da10f1, data=[0x02, 0x3e, 0x00, 0x55, 0x55, 0x55, 0x55, 0x55], is_extended_id=True, is_rx=False)
bus.send(msg)
recv_msg = bus.recv(timeout=1.0)
```

### Expected behavior
```
> python -m can.logger -i seeedstudio -c COM12
Connected to SeeedBus: Serial interface: COM12
