Hi, Here is some more info on this that might help someone. Note that I was previously using SUSE 9.3 and am now using SUSE 10.1. The Serial Port number was increased because I had a link to /dev/ttyUSB0 /dev # ls -als | grep USB 0 lrwxrwxrwx 1 root root 12 2006-11-28 10:44 pilot -> /dev/ttyUSB0 0 crw-rw---- 1 root uucp 188, 0 2006-11-27 16:12 ttyUSB0 When the USB Serial port cable is unplugged and re-inserted then it (usbfs) would create a new device /dev/ttyUSB1, however, if the USB Serial cable is removed then this new device disappears. Therefore, I guessed that /dev/ttyUSB0 is not being removed because it is in use, or appears to be because of the link. Removal of the link to /dev/ttyUSB0 fixed the problem. Note that to get Kpilot to work, it must be pointed directly to /dev/ttyUSB0. Now with kpilotdeamon running in the background the /dev/ttyUSB0 does not disappear. After, killing the kpilotdeamon the /dev/ttyUSB0 disappeared and then on reinserting the USB Serial Port device was mapped to /dev/ttyUSB0 again. So, the key here is that when a USB device is removed then the associated application or deamon must be stopped or atleast stop using the device, so that the usbfs can remove the device. In order for this to happen the application or deamon must be given a message from the usbfs that the device has been removed and therefore to release the device. Would it be possible to improve the system to make this more user friendly? Thanks, On Friday 03 March 2006 00:54, Bruce Samhaber wrote:

Hi,

I am using a USB to Serial port cable. Initially when I start the computer and linux then insert the USB Serial port cable the device is set as /dev/ttyUSB0. If the USB Serial Port cable is removed then reinserted it becomes /dev/ttyUSB1. Each time the USB Port cable is removed then reinserted the device name is increased by one.

It appears to me that upon removeal of the device that SUSE Plugger is no removeing the device from the device list.

Has anyone seen this problem? Does anyone have any suggestions to fix this?

Thanks,
