ich habe es ja schon verschoben :)


>> eis # cat /usr/lib/udev/rules.d/85-usb.rules
>> SUBSYSTEMS=="usb", ATTRS{idProduct}=="6001", ATTRS{idVendor}=="0403",
>> ATTRS{serial}=="A800dw2t", SYMLINK+="plus-test"

trotzdem bleibt ein Phänomen - evtl. gibt es dazu ja auch noch eine Idee :)

nach Neustart:
eis # ls -l /dev | grep hdreader
lrwxrwxrwx 1 root root           7 Jan 12 18:58 hdreader -> ttyUSB0

dann Gerät gezogen und wieder angestöpselt hat auch neue ttyUSB Nummer 
bekommen:

eis # dmesg | grep tty
[    6.216825] usb 1-4: FTDI USB Serial Device converter now attached to 
ttyUSB0
[    8.598071] ftdi_sio ttyUSB0: use of SPD flags is deprecated
[   10.916666] ftdi_sio ttyUSB0: use of SPD flags is deprecated
[ 1147.657649] ftdi_sio ttyUSB0: error from flowcontrol urb
[ 1147.657930] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now 
disconnected from ttyUSB0
[ 1150.740831] usb 1-4: FTDI USB Serial Device converter now attached to 
ttyUSB1

danach wird das Gerät über die USB Bus Nummer (bus/usb/001/004) 
angebunden und funktioniert nicht:

eis # ls -l /dev | grep hdreader
lrwxrwxrwx 1 root root          15 Jan 12 19:17 hdreader -> bus/usb/001/004

erst wenn ich dann "eis # udevadm test /dev/ttyUSB1" (kompletter Auszug 
unten in der Antowrt) ausführe ändert sich das auf den nun korrekten 
device-namen:

eis # ls -l /dev | grep hdreader
lrwxrwxrwx 1 root root           7 Jan 12 19:24 hdreader -> ttyUSB1


verstehe ich nicht (?!)

Viele Grüße
Fabian
