Re: [Gambas-user] Gambas2 USB detect !!??
drive. I haven't hooked any USB drives up to my Ubuntu server since I upgraded so I don't know if every distro has logs that look like that, or just Mandriva. Rob Good idea - /var/log/messages should be present on every linux looking in there can provide interesting infos... (be base for usefull GUI apps). May be coupled with comparing current time / log time in order to look only for current events... The problem ist - as normal user you are not allowed to read it... regards Emil -- ___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user

You (or better the administrator) can create a named pipe (with mknod) and direct parts of the log infos additionally to this named pipe. So the syslog.conf needs to be edited and a line like kern.info | YourNamedPipe may be added, which say, the all the log messeages from the kernel shout additional go throug the named pipe. Of course the syslog-daemen needs to be restartet or instructed to reread its config file.

USB driver letter ??? That does not exist on Linux... Anyway, this is not possible in Gambas 2 directly. AFAIK, when you plug a device, the kernel warns the HAL daemon which then sends a signal on the DBUS system bus. This signal then can be catched by any application that ask for it on the DBUS system bus. You cannot do that in Gambas without support for DBUS. Maybe there is another way with a command-line tool, but I don't know.

Linux doesn't have drive letters, but you should be able to get the device name (e.g. /dev/sde) in a couple of different ways. The correct way to do it is to set your program up as a hotplug agent for USB drives using udev (probably putting a file in /etc/udev/rules.d). But doing that may screw up your users' normal hotplug functionality (i.e. KDE or GNOME asking the user what they want to do with the drive.) Google for udev hotplug for more information on this, because I've never done it myself. Also, on older systems the devfs system was used rather than udev and you'd need to deal with /etc/hotplug/usb.usermap (I think.) Another way, less intrusive but by no means foolproof, is to have a process running in your Gambas program, tail -f /var/log/messages or tail -f /var/log/syslog. Here is what appeared in /var/log/messages last night on one of my Mandriva boxes when I attached my Archos hard disk jukebox: Jan 1 20:46:59 raindog2 kernel: usb 5-5: new high speed USB device using ehci_hcd and address 7 Jan 1 20:46:59 raindog2 kernel: usb 5-5: configuration #1 chosen from 1 choice Jan 1 20:46:59 raindog2 kernel: scsi7 : SCSI emulation for USB Mass Storage devices Jan 1 20:47:04 raindog2 kernel: Vendor: ArchosModel: PC Hard Drive Rev: 0316 Jan 1 20:47:04 raindog2 kernel: Type: Direct-Access ANSI SCSI revision: 02 Jan 1 20:47:04 raindog2 kernel: SCSI device sdh: 312175080 512-byte hdwr sectors (159834 MB) Jan 1 20:47:04 raindog2 kernel: sdh: Write Protect is off Jan 1 20:47:04 raindog2 kernel: sdh: assuming drive cache: write through Jan 1 20:47:04 raindog2 kernel: SCSI device sdh: 312175080 512-byte hdwr sectors (159834 MB) Jan 1 20:47:04 raindog2 kernel: sdh: Write Protect is off Jan 1 20:47:04 raindog2 kernel: sdh: assuming drive cache: write through Jan 1 20:47:04 raindog2 kernel: sdh: sdh1 Jan 1 20:47:04 raindog2 kernel: sd 7:0:0:0: Attached scsi removable disk sdh If you look for the words Attached scsi removable disk in the output of that tail -f, the next word in that line should be the device name of the drive.
