# Version: 1.1.0
|
||||
# - fix "PCAN-USB Chip" into "PCAN-Chip USB" in comment
|
||||
# - handle not yet known (future?) PEAK USB adapters
|
||||
# - add command line options -v, -u and -p
|
||||
#
|
||||
# Version: 1.2.0
|
||||
# - use lspci -n to fix PCAN-PCI card non-detection
|
||||
# - pass device name as a awk variable instead of reading it from input stream
|
||||
