Dizüstü bilgisayarımda aynı seri USB adaptörünü kullanıyorum (Ubuntu 9.10). Adaptörler Sabrent tarafından üretilmiştir ve aşağıdaki gibi gösterildiği gibi bir Prolific PL2303 IC etrafında üretilmiştir lsusb
:
Bus 001 Device 008: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Bus 001 Device 007: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Bus 001 Device 006: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Tarafından görüntülenen özniteliklerin hiçbiri udevadm
belirli bir adaptöre özgü görünmüyor:

Adaptörlerin tümü tek bir USB hub'ına takılı. Bağdaştırıcılar arasında ayrım yapamadığım için, bağdaştırıcının göbeğindeki hangi fiziksel bağlantı noktasına takılı olduğuna bağlı olarak her bağdaştırıcının adını düzelten bir udev kuralı yazmam mümkün mü?
