USB kabel pl2303 k NOKII a kernel 2.6.12-1.1378_FC3smp - odpojovani

[Zdeněk Habala]

Zdravim,
mam PC s RH Fedora Core 3, kernel 2.6.12-1.1378_FC3smp. K USB pripojen kabel
pro Nokii 6020 (kabel je s chipem pl2303). V messages mam cca jednou za
hodinu takovyto vypis:

Nov 20 21:06:42 localhost kernel: hub 2-0:1.0: port 2 disabled by hub
(EMI?), re-enabling...
Nov 20 21:06:42 localhost kernel: usb 2-2: USB disconnect, address 13
Nov 20 21:06:42 localhost kernel: PL-2303 ttyUSB1: PL-2303 converter now
disconnected from ttyUSB1
Nov 20 21:06:42 localhost kernel: pl2303 2-2:1.0: device disconnected
Nov 20 21:06:42 localhost kernel: usb 2-2: new full speed USB device using
uhci_hcd and address 14
Nov 20 21:06:42 localhost kernel: pl2303 2-2:1.0: PL-2303 converter detected
Nov 20 21:06:42 localhost kernel: usb 2-2: PL-2303 converter now attached to
ttyUSB1


Jakoby se kabel odpojil a zase pripojil. Problem je v tom, ze on pri tom
prepojovani meni porty, jednou je na ttyUSB0, jednou na ttyUSB1 a to zcela
nahodne. Nevi nekdo, v cem by mohl byt problem ?
