Recommendation
________________________________________________________________________
To consistently assign a device name to a devc-serusb device:
1. the devices should remain static, avoid removing them
2. specify busno, devno, did, vid and unit option at the command line, this information is provided by the '# usb -vvv' utility.
Example using three devc-serusb devices:
devc-serusb -d busno=3,devno=1,did=0x2303,vid=0x067b,unit=1
waitfor /dev/serusb1 5
devc-serusb -d busno=3,devno=2,did=0x2303,vid=0x067b,unit=2
waitfor /dev/serusb2 5
devc-serusb -d busno=2,devno=1,did=0x2303,vid=0x067b,unit=3
waitfor /dev/serusb3 5
