two ACM devices does not function together
I use hokuyo lidar and arduino for my application. Hokuyo is connected to laptop directly and it is connected as ACM port. Arduino board connected to the laptop is ACM1. Now, whenever I upload a new code in arduino using rosserial, while the lidar is also connected to the laptop, it shows following error.
avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer is not responding
If I remove either of the device from the laptop, then the other one works. Please do help !
